History of

The word photography derives from the Greek words phōs (genitive: phōtós) light, and gráphein, to write. The word was coined by Sir in 1839.

A obscura box used for drawing images

Photography is the result of combining several different technical discoveries. Long before the first were made, Chinese philosopher Mo Ti and Greek mathematicians Aristotle and Euclid described a in the 5th and 4th centuries BC.[1][2] In the 6th century CE, Byzantine mathematician Anthemius of Tralles used a type of in his experiments[3] Ibn al-Haytham (Alhazen) (965±1040) studied the camera obscura and pinhole camera,[2][4] Albertus Magnus (1193/1206-1280) discovered silver nitrate, and Georges Fabricius (1516±1571) discovered silver chloride. Daniel Barbaro described a diaphragm in 1568. Wilhelm Homberg described how light darkened some chemicals (photochemical effect) in 1694. The novel Giphantie (by the French Tiphaigne de la Roche, 1729±1774) described what can be interpreted as photography.

Early History: Development of chemical photography

[edit] Monochrome process

Nicéphore Niépce's earliest surviving of a scene from nature, circa 1826, "View from the Window at Le Gras," Saint-Loup-de-Varennes (France).

"Boulevard du Temple", taken by in late 1838 or early 1839, was the first-ever photograph of a person. It is an image of a busy street, but because time was over ten minutes, the city traffic was moving too much to appear. The exception is a man in the bottom left corner, who stood still getting his boots polished long enough to show up in the picture.

Robert Cornelius, self-portrait, Oct. or Nov. 1839, approximate quarter plate . The back reads, "The first light picture ever taken." This self-portrait is the first photographic portrait image of a human ever produced.

The first permanent photograph (later accidentally destroyed) was an image produced in 1826 [5] by the French inventor Joseph Nicéphore Niépce. His photographs were produced on a polished pewter plate covered with a petroleum derivative called bitumen of Judea. Bitumen hardens with exposure to light. The unhardened material may then be washed away and the metal plate polished, rendering a image which then may be coated with ink and impressed upon paper, producing a print. Niépce then began experimenting with iron compounds based on a Johann Heinrich Schultz discovery in 1724 that an iron and chalk mixture darkens when exposed to light.

In partnership, Niépce (in Chalon-sur-Saône) and Louis Daguerre (in ) refined the existing silver process.[6] In 1833 Niépce died of a stroke, leaving his notes to Daguerre. While he had no scientific background, Daguerre made two pivotal contributions to the process. He discovered that exposing the silver first to iodine vapour before exposure to light, and then to mercury fumes after the photograph was taken, could form a latent image. the plate in a salt bath then fixes the image. On January 7, 1839 Daguerre announced that he had invented a process using silver on a copper plate called the daguerreotype.[7] The French government bought the patent and immediately made it public domain.

In 1832, French-Brazilian painter and inventor Hercules Florence had already created a very similar process, naming it Photographie.

After reading about Daguerre's invention, Fox Talbot worked on perfecting his own process; in 1839 he acquired a key improvement, an effective fixer, from John Herschel, the astronomer, who had previously showed that hyposulfite of soda (also known as hypo, or now sodium thiosulfate) would dissolve silver salts. Later that year, Herschel made the first glass n egative.

By 1840, Talbot had invented the calotype process. He coated paper sheets with silver chloride to create an intermediate negative image. Unlike a daguerreotype, a calotype negative could be used to reproduce positive prints, like most chemical films do today. Talbot patented [8] this process, which greatly limited its adoption. He spent the rest of his life in lawsuits defending the patent until he gave up on photography. Later George Eastman refined Talbot's process, which is the basic technology used by chemical film today. Hippolyte Bayard had also developed a method of photography but delayed announcing it, and so was not recognized as its inventor.

In 1839, John Herschel made the first glass negative, but his process was difficult to reproduce. Slovene Janez Puhar invented a process for making photographs on glass in 1841; it was recognized on June 17, 1852 in Paris by the Académie Nationale Agricole, Manufacturière et Commerciale. [9] In 1847, Niépce St. Victor published his invention of a process for making glass plates with an albumen emulsion; the Langenheim brothers of Philadelphia and John Whipple of Boston also invented workable negative-on-glass processes in the mid 1840s.[10]

In 1851 Frederick Scott Archer invented the collodion process.[citation needed] Photographer and children's author used this process.[citation needed]

Roger Fenton's assistant seated on Fenton's photographic van, Crimea, 1855.

Herbert Bowyer Berkeley experimented with his own version of collodian emulsions after Samman introduced the idea of adding dithionite to the pyrogallol developer.[citation needed] Berkeley discovered that with his own addition of sulfite, to absorb the sulfur dioxide given off by the chemical dithionite in the developer, that dithionite was not required in the developing process. In 1881 he published his discovery. Berkeley's formula contained pyrogallol, sulfite and citric acid. Ammonia was added just before use to make the formula alkaline. The new formula was sold by the Platinotype Company in London as Sulpho-Pyrogallol Developer.[11]

Nineteenth-century experimentation with photographic processes frequently became proprietary. The German- born, New Orleans photographer Theodore Lilienthal successfully sought legal redress in an 1881 infringement case involving his "Lambert Process" in the Eastern District of Louisiana.

[edit] Popularization

General view of The Crystal Palace at Sydenham by Philip Henry Delamotte

The daguerreotype proved popular in responding to the demand for portraiture emerging from the middle classes during the Industrial Revolution.[citation needed] This demand, that could not be met in volume and in cost by oil painting, added to the push for the development of photography.

In 1847, Count Sergei Lvovich Levitsky designed a bellows camera which significantly improved the process of focusing. This adaptation influenced the design of cameras for decades and is still found in use today in some professional cameras.[citation needed] While in Paris, Levitsky would become the first to introduce interchangeable decorative backgrounds in his photos, as well as the retouching of negatives to reduce or eliminate technical deficiencies.[citation needed] Levitsky was also the first photographer to portray a photo of a person in different poses and even in different clothes (for example, the subject plays the piano and listens to himself). [citation needed] and Philip Henry Delamotte helped popularize the new way of recording events, the first by his Crimean war pictures, the second by his record of the disassembly and reconstruction of The Crystal Palace in London. Other mid-nineteenth-century established the medium as a more precise means than engraving or lithography of making a record of landscapes and architecture: for example, Robert Macpherson's broad range of photographs of Rome, the interior of the Vatican, and the surrounding countryside became a sophisticated tourist's visual record of his own travels.

By 1849, images captured by Levitsky on a mission to the Caucasus, were exhibited by the famous Parisian optician Chevalier at the Paris Exposition of the Second Republic as an advertisement of their lenses. These photos would receive the Exposition's gold medal; the first time a prize of its kind had ever been awarded to a photograph.[citation needed]

That same year in 1849 in his St. Petersburg, Russia studio Levitsky would first propose the idea to artificially light subjects in a studio setting using electric lighting along with daylight. He would say of its use, "as far as I know this application of electric light has never been tried; it is something new, which will be accepted by photographers because of its and practicality". [citation needed]

In 1851, at an exhibition in Paris, Levitsky would win the first ever gold medal awarded for a portrait photograph.[citation needed]

In America, by 1851 a broadside by daguerreotypist Augustus Washington were advertising prices ranging from 50 cents to $10.[12] However, were fragile and difficult to copy. Photographers encouraged chemists to refine the process of making many copies cheaply, which eventually led them back to Talbot's process.

Ultimately, the modern photographic process came about from a series of refinements and improvements in the first 20 years. In 1884 George Eastman, of Rochester, New York, developed dry gel on paper, or film, to replace the so that a photographer no longer needed to carry boxes of plates and toxic chemicals around. In July 1888 Eastman's Kodak camera went on the market with the slogan "You press the button, we do the rest". Now anyone could take a photograph and leave the complex parts of the process to others, and photography became available for the mass-market in 1901 with the introduction of the Kodak Brownie.

In the twentieth century, photography developed rapidly as a commercial service. End-user supplies of photographic equipment accounted for only about 20 percent of industry revenue. For the modern enthusiast photographer processing film, little has changed since the introduction of the 35mm film in 1925.[citation needed]

The first digitally scanned photograph was produced in 1957. The digital scanning process was invented by Russell A. Kirsch, a computer pioneer at the National Institute of Standards and Technology. He developed the system capable of feeding a camera's images into a computer. His first fed image was that of his son, Walden Kirsch. The photo was set at 176x176 . [13]

[edit] process

First color image, photograph by James Clerk Maxwell, 1861.

Although was explored throughout the 19th century, initial experiments in color resulted in projected temporary images, rather than permanent color images. Moreover until the 1870s the emulsions available were not sensitive to red or green light.

The first color photo, an additive projected image of a tartan ribbon, was taken in 1861 by the Scottish physicist James Clerk Maxwell.[14] Several patentable methods for producing images (by either additive or subtractive methods, see below) were devised from 1862 on by two French inventors (working independently), Louis Ducos du Hauron and Charles Cros.[15] Practical methods to sensitize silver halide film to green and then orange light were discovered in 1873 and 1884 by Hermann W. Vogel, but full sensitivity to red light was not achieved until the early years of the 20th century.

The first fully practical color plate, Autochrome, did not reach the market until 1907. It was based on a screen - plate method, the screen (of filters) being made using dyed dots of potato starch. The screen lets filtered red, green or blue light through each grain to a photographic emulsion in contact with it. The plate is then developed to a negative, and reversed to a positive, which when viewed through the screen restores approximating the original.

Other systems of color photography included that used by Sergei Mikhailovich Prokudin-Gorskii, which involved three separate monochrome exposures ('separation negatives') of a still scene through red, green, and blue filters. These required a special machine to display, but the results are impressive even by modern standards. His collection of glass plates was purchased from his heirs by the Library of Congress in 1948, and is now available in digital images.

[edit] Development of

Main article: Digital photography A Canon PowerShot A95

The charge-coupled device (CCD) is the most important invention for digital photography[citation needed]. It was invented in 1969 by Willard Boyle and George E. Smith at AT&T Bell Labs. The lab was working on the Picturephone and on the development of semiconductor bubble memory. Merging these two initiatives, Boyle and Smith conceived of the design of what they termed 'Charge "Bubble" Devices'. The essence of the design was the ability to transfer charge along the surface of a semiconductor.

y 1973 - Fairchild Semiconductor releases the first large image forming CCD chip; 100 rows and 100 columns[citation needed]. y 1975 - Bryce Bayer of Kodak develops the Bayer filter mosaic pattern for CCD color image sensors y 1986 - Kodak scientists develop the world's first megapixel sensor.

The web has been a popular medium for storing and sharing photos ever since the first photograph was published on the web by Tim Berners-Lee in 1992 (an image of the CERN house band Les Horribles Cernettes). Today popular sites such as Flickr, Picasa and PhotoBucket are used by millions of people to share their pictures

Trends in digital photography: The good commentary

A photographic landmark of sorts took place at the end of 2010. Dwayne's Photo accepted the last roll of Kodachrome slide film for processing. Kodachrome was long a favorite of many professionals and advanced amateurs but required a unique and complex development process; Dwayne's was the last lab to provide this service.

Digital has replaced film for most, pros and amateurs alike. And it's not standing still. The current trends are mostly positive--which isn't to say there aren't a few product and technology areas that couldn't stand improvement.

Here I look at the good. A future post will look at the not so good.

Nondestructive image editing programs like Adobe's Lightroom are one of the more positive trends we've seen in digital photography over the past few years.

(Credit: Gordon Haff)

The megapixel wars subside. For a time, camera makers vigorously proclaimed how their camera sensors had more megapixels than the competition. This made some sense in the early days of digital photography when cameras really didn't have enough sensor sites to deliver the resolution needed for making even modest-sized prints at high quality. However, for most purposes, more pixels don't much improve image quality past a certain point and crowding more pixels into a given area means that individual pixels have to be smaller. The relationship between resolution, size, noise, and dynamic range is far more complex than simple sound bites can capture. Smaller pixels don't always mean more noise--which is a particular problem when sensitivity is cranked up to shoot in dim light. But there are tradeoffs and those were hard for camera designers to make optimally so long as the camera's megapixel count was front and center in every advertisement.

It was noteworthy therefore when, in late 2009, Canon revealed that its new Canon Powershot G11 model would actually have a lower megapixel count than its predecessor. This event played a big part in reducing the emphasis placed on megapixels. (At least in cameras; the megapixels war rages on with mobile phones.) And this, in turn, is one of the factors that has allowed for cameras with fast and low -noise sensors that can take quality pictures in very little light.

The photo editing revolution. nostalgia I might have for black-and-white work, digital editing has a lot of good things going for it. But relatively new image -editing programs, most notably Adobe Lightroom and Apple , truly transform organizing and touching up large catalogs of photos.

A program like Photoshop works by changing the values of the pixels making up an image and then saving the changed image to disk. This type of editing provides a very high level of control but it also means that each edited version of a photo needs to be saved as a separate file. In addition, while such programs have various tools to automate a set of changes to a group of photos, these tools aren't especially intuitive or easy to use. This shouldn't be especially surprising; Photoshop was developed primarily for graphics professionals who might typically spend several hours getting a single image just-so.

Lightroom and Aperture take a completely different approach. They are "nondestructive." This means that editing actions are saved separately from the photo; they're only applied directly to a photo's pixels if the photo is exported--for example, to upload to a photo-sharing site.

You do give up much of the ability to make changes to just part of a photo rather than to the photo as a whole. For that fine-grained level of control, you still need to use a traditional editing program. However, I seldom find myself needing to do so. These programs really do deliver a revolutionary experience. If you're a halfway serious photographer, you really owe it to yourself to at least give a free trial a whirl. (Aperture retails for $199 and Lightroom for $299.)

High-end point-and-shoots. In the twilight of film as a mass-market medium, one of the annoying product holes--to me at least--was the space that used to be filled by mid-priced rangefinder cameras like the Canon QL17. These were fairly compact and had lots of manual control. However, as autofocus, zoom lenses, and other modern conveniences became ubiquitous, the camera market largely bifurcated into small point-and- shoots primarily designed for unsophisticated users to take snapshots and much bulkier SLRs offering the full range of control.

Those of us who wanted something that was both physically small and offered a reasonable degree of control over aperture, speed, and so forth were pretty much stuck with buying used cameras. To be sure, this wasn't a bad option with film cameras except that some of the more interesting camera models were also highly prized collectibles, and therefore expensive.

A number of camera models fill this space quite well in the digital realm. The Canon Powershot Gx line was arguably first but Nikon (with the Coolpix P7000) and Panasonic (with the Lumix LX5) now have competitive products with similar capabilities. They're pocketable (with a big pocket) but they offer a high level of manual control. Their sensors are small and they're still a bit sluggish if you're used to a digital SLR, but each model iteration gets a bit better.

People with different needs doubtless find other trends interesting. For example, a lot of videographers love that video has come to full-frame dSLRs because of the quality and depth-of-field control they provide. And we're seeing early examples of enhancing dynamic range in-camera by taking multiple exposures and automatically correcting exposures for known lens distortions. There's a lot happening

Types of Photography

Fashion Photography: This genre of photography is one of the most lucrative kinds. Photographs are one of the most effective ways of communication in the world of fashion. Here, photography is used to bring attention to the clothes and the accessories. Models are exclusively selected to showcase products in the best way possible. Fashion photographers today create the particular look, either in natural environment or one that is created in the studio. Often, these fashionable photographs find their way in the leading fashion magazines. These magazines cater to the niche crowd that loves to know the best in clothing and other fashion accessories.

Glamor Photography: Glamor photography is also about fashionable visuals, however with a touch of difference. Glamor photography highlights the model in a different light rather than laying emphasis on the clothing or accessories. Often, nude images are also a part of glamor photography. These can be found on the covers of magazines like µPlayboy¶.

Advertising Photography: Advertising photography is all about creating the right environment to highlight the product to be advertised in the best way possible. The photographers generally come up with ideas or visuals or at times, design houses also brief photographers with the concept required in order to obtain the specific results. These photographs are always planned in co-ordination with the advertising firm.

Still Life Photography: is all about capturing objects on camera that are deliberately grouped together to create a particular composition. This form of art requires the photographer to have an excellent sense of composition and lighting. A photographer in this case can create different textures and use objects that add interest to an otherwise normal composition.

Wedding Photography: Wedding photography is a specialized field of this art form, which is dedicated to snapping the most memorable moments in various creative ways. A photographer can take his/her own approach towards this subject. While some prefer the traditional µposed¶ ways, there are others who base their photographs purely on the actual moment. Photographers can also make these pictures fashionable with particular themes if agreeable with the client. There are many cases where such glamorous wedding photographs are captured especially in the studio. Today, many people are willing to explore new ideas, which open up many new creative avenues for experts in wedding photography.

Fine Art Photography: Fine art photography is all about visuals that resemble a work of art. These are highly creative images that have an abstract appeal. Therefore, these photographs can be equivalent to an artist¶s expression on canvas. This genre of photography is not restricted for commercial purposes but could be used for creative pursuits as well. A fine art photographer should have the ability to look beyond the obvious settings.

Nature Photography: Nature photographers are very much sought-after by media houses. Works of these creative geniuses can be seen in magazines like µNational Geographic¶. Nature photography encompasses various other types of photography, such as-

Landscape Photography: These photographs mainly highlight the natural beauty of any place. It includes areas of wilderness, deserts, mountains or even waterfalls.

Wildlife Photography: Photographers that specialize in wildlife photography spend many hours in the wilderness to capture some of the most amazing shots of animals against a natural backdrop. A photographer in this case, would need to be an ardent animal lover and know his way around in the wild.

Underwater Photography: Underwater photography is an interesting art form that explores a whole new world beneath the deep blue seas. It¶s an extremely challenging task because a photographer should be equipped with all the knowledge about swimming and scuba diving to capture the best images while swimming in the blue waters!

Seascape Photography: Capturing nature in her many moods would be interesting for all lovers of the environment. A photographer who is dedicated completely to seascape photography should always lie in wait for the beauty of the sea to unfold. Here the concentration is mainly on capturing various moods of the ocean, at different times of the day or even seasons!

Cloudscape Photography: This genre of photography is completely dedicated to capturing various images of the cloud formations. Black and white photography in particular can be creatively used for this branch of photography.

Travel Photography: Travel photography involves capturing images of a particular landscape or even people from different countries. A photographer who is dedicated to this type of photography captures various traditions and customs of a place.

Architectural Photography: Architectural photography, as the name suggests, is all about the capturing images of different styles o f architecture in different lights. This type of photography would require the photographers to be an expert in the technical, as well as the visual department.

Portrait Photography: Portrait photography is all about capturing the mood of a person with an emphasis on the face and expression of a person. This style of photography need not only be about professional models, it can encompass any kind of a person. Family portrait photographs are very much in demand but this does not mean it¶s all about a basic snapshot. There are many creative ways a photographer can use to make a portrait photograph look equally stunning!

Photojournalism: Photojournalism is all about telling a story about a particular event or incident through a single photograph. This genre of photography is used mainly by publications to represent the latest news. In this case, the photographer¶s visuals and the writer¶s story should compliment each other. For example, if a writer is making a specific mention of a particular location in the story, the photographer can find innovative ways to capture the same on camera. Photojournalism can be further classified into ±

Documentary photography: Here, the photographer has to present an image that best represents the incident being spoken of in true form. In this case, press photographers usually submit their images to the concerned publication but in recent times, press photographers from all over the world often display these at exhibitions as well.

Street Photography: This is all about capturing candid images of public places or even people in their natural element. A photographer in this case requires the knack to mingle between people and capture the best frames without being conscious of people around. Henri Cartier-Bresson used the technique of wrapping the camera inside his handkerchief. Of course, one also has to consider the legal issues, as there are many places where this type of photography is prohibited for security reasons.

Celebrity Photography: Celebrity photography is all about capturing celebrities from various fields. Various media houses use such photographs - from publications (magazines, newspapers) to the online media. In this case there are various ways of approaching this subject. In the first instance, celebrities are shot with meticulous planning in a studio or at an outdoor location where the styling is well planned for; this includes the clothes, make up and the accessories. Apart from this, photographers who specialize in celebrity photography also need to capture them at various functions or press conferences. Where as, there is a third type of celebrity photography known as the paparazzi. This is about capturing celebrities on camera without their consent. These photographs are exclusive and often fetch the premium price for all photographers.

Sports Photography: This genre of photography is dedicated completely to capturing the best images in action, for any kind of sports. A photographer in this case should have the knack to capture stunning images on camera with great speed. There are many photographers who have dedicated themselves completely to this segment. These photographs are mainly used by publishing houses and other branches of media.

Nude Photography: Nude photography is about the depiction of the human body in nude form. These photographs are not meant for but purely for the study of the human body. Here, the face is not always the focal point and the compositions are stylized with experimentation in terms of light and backdrops.

War Photography: is about capturing photographs that depict the situations at war in terms of the people or the particular situation. Here, the photographers are always at risk and often the target of the warring groups.

Candid Photography: Henri Cartier-Bresson is one of the first names that crops up in one¶s mind when it comes to candid photography. This can be said to be one of the purest forms of photography, which does not include any staged situations. Candid photography is all about being spontaneous!

Fire Photography: This form of photography would require the photographer to be equipped with protective clothing. The photographer in this case, clicks photographs of operations. This type of photography is useful for investigations.

Forensic Photography: Also known as crime scene photography, here the job of the photographer is mainly to capture images for an accurate representation of the scene of crime. Here, a photographer will have to cover all the possible angles of the particular scene for investigation purposes. These images could be about any scene of crime or even accidents.

Secret Photography: Here, it is the primary aim of the photographer to capture images of people without their knowledge. Professional photographers mainly use this type of photography for investigative purposes and unethical publication of the same can result in various legal issues. Here, the photographer can also conceal himself/herself from the concerned party including the camera being used.

Macro Photography: This style of photography is completely about close-up images of the particular subject. This style is used particularly to capture details of organisms or nature that may not be visible to the naked eye.

Aerial Photography: A photographer in this case, needs to be an expert at capturing images from an elevated position. There are various techniques used to obtain these images; a photographer can click these images from a helicopter or an aircraft and more recently, kites are also being used wherein the camera is attached to the kite to click photographs when the kite is in the air.

Headshot Photography: This type of photography focuses mainly on the person¶s face (mug shots) but is different from portrait photography. The images in this case are plainer in nature as the client would need to use these images purely for work purposes.

Food Photography: Food photography is mainly in demand due to the rising needs from the advertising industry and publishing houses. It is the photographer¶s skill that is required to make the group of objects look very i nteresting and appealing to the viewer.

Astrophotography: Photographers in this case focus completely on capturing images from space. This could range from the planets to the stars or any other interesting formations. It is very difficult to capture a clear image of any incident in the starry skies owing to many technical problems a photographer may face. However, with the advent of new technology in this field, many innovative options are being added to make this type of photography easier for avid photographers dedicated to this field.

Child Photography : In this case, the photographer should definitely have a knack to handle children to capture their best moods and moments! These types of photographs are used for advertising purposes or even for personal reasons.

Black and White Photography: With the advent of color photography, black and white photography would have been passé. However, this is a medium that offers vast options for photographers. The timeless appeal of black and white photography can be used for any topic. Photographers in this case would need to use lighting and textures apart from composition and latest techniques to be rewarded with beautiful visuals.

Digital Photography: Digital photography is all about photographers opting for the digital cameras over the traditional ways to click images that are faster to transmit. However, there are many photographers who still prefer to use film to digital cameras for better clarity and representation of light and dark.

Night Photography: Photographers in this case completely specialize in night scenes. Due to the problem of minimum light, new techniques are being incorporated. A photographer can use artificial light or even a long exposure to capture clear and precise images.

These various types of photography clearly give an indication of the blossoming of this art form. Technology has made it possible to go beyond the obvious frames. Today, photography is about the combination of the expertise of the photographer as well as techniques. But in the true sense, an excellent photographer would only need creativity and strong powers of observation to be able to capture visuals that are truly beyond the ordinary

Difference Between SLR and DSLR

Pictures are an integral part in keeping memories. Before the days of digital photography, there was film. Although film has started to disappear from the general public view in the last few years, it¶s where we begin our discussion.

SLR or Single Lens Reflex camera are a class of cameras that allowed for much better photographs due to an innovative solution to an old problem. Most cameras have two light paths from the target, one leading to the lens itself while the other to the viewfinder. This leads to the final photo being slightly different from what you saw on the viewfinder. SLR cameras fixed this by using a certain mechanism that lets you see through the lens. After you push the button to take the picture, the mechanism then moves to let the light hit the film behind it. Most SLR¶s are used in professional photography, where the need for utmost quality is very high. It would not be surprising that most of the advanced features also appear on SLRs and not on the common camera.

At the early stages of photography, the LCD viewfinder grew in popularity. Since the LCD viewfinder usually takes its image on the , it should already be considered as an SLR; but it isn¶t. SLRs have begun to become a class of high end cameras with more advanced features, like manual controls, interchangeable lenses, among others. It was no longer just about the path of light.

DSLR or the Digital version of SLR is basically an SLR that has been converted from saving the image in film to saving an image in a memory card. It still shares a lot of the advanced features of the SLR along with a few more improvements that makes it a lot more superior.

The nature of memory cards and the high capacities that are available today means that a professional photographer would not need to change the storage medium as often. The use of very high quality sensors coupled with the capability to instantly review the image you took also gives modern day photographers an undeniable edge.

Despite being a few folds more expensive compared to their counterparts, the SLR and the DSLR were an indispensable tool in professional photography. Even hobbyists who have the money can enjoy and enhance their talents on photography. As most technologies evolve, so does the technology in photography. The DSLR is just the next evolutionary step from the SLR.

The first major difference between SLRs and digital compact cameras is what prevents most people from buying an SLR: price.

Even though digital SLR prices have come down each and every year, they are still significantly more expensive than their compact cousins.

Let me put it this way: an inexpensive digital SLR camera starts around $450 without a lens. Then you get to tack on an additional $100 for a kit lens or $500 for a high-quality zoom.

If you can't fathom spending $500 to $1,000 on a , then an SLR is definitely not right for you.

However, if you've been saving you pennies for months and are perfectly aware of how much these cameras cost, then let's take a closer look at some of the other differences between SLRs and digital compacts.

Size and Weight

Anyone who wants a camera that fits in their pocket can forget all about digital SLRs.

Size and weight is the second most obvious difference between SLR and compact digital cameras after price. Even a small-sized digital SLR camera is twice the size and bulk of a compact camera.

While there are many new digital SLR models that are more portable (and are easier to travel with) the addition of a lens to your camera ensures that you'll never be able to stow it away in your shirt pocket or purse.

If you'd like the higher image quality of a digital SLR but don't want a huge heavy camera, then consider a mirrorless DSLR - they're more the size of compacts but capture DSLR-like photos (and you can change lenses).

Professional Movies

Prior to 2008, digital SLRs with video did not exist.

Digital SLR cameras could only take stills, and many people were suprised that these big expensive cameras could not capture video clips like their tiny compact cousins. All that is now in the past: virtually all DSLRs released since 2008 include a High Definition (HD) video capture mode.

But the one thing that really sets DSLR video apart from compact video is the ability to change lenses.

Since you can change lenses on your DSLR, you can capture videos that look more like movies: extreme wide- angle shots, close-ups and backgrounds thrown nicely out of focus can all be achieved with a digital SLR.

This explains why many small independent film companies now use DSLRs as their camera of choice. Compared to the price of a high-end digital video camera, a DSLR is pretty cheap.

Manual Zoom

Compact digital cameras have electronic zooms: push a button (or lever) and the camera's lens zooms in and out.

Since all digital SLR lenses can be removed from the camera body, the zoom mechanisms are entirely manual: to change the view you have to twist a ring on the lens.

This manual zoom actually results in a faster zoom: you don't have to wait for the motors to move the lens in and out, you can twist the zoom ring as fast or slow as you like.

Zoom Range

Since we're on the topic of lenses, let's talk about another difference between SLR and compact digital cameras: zoom range.

There are many compact cameras on the market today with "mega-zooms". These cameras have 10x or 12x zooms and are capable of taking both wide angle and telephoto shots.

In order to cover a similar range with a digital SLR you have one of two options:

y Buy a mega-: these give you the same zoom power as a 10x zoom on a compact, but also cost about $600 USD y Buy two zoom lenses: with one wide-angle zoom and one telephoto you can cover a lot of range, but at a significant cost ($800 USD or more)

If tons of zoom range is important to you, the compact is clearly the more econ omical solution.
