Getting to Know Bridge, Camera Raw, and Photoshop 05_774820 ch01.qxp 1/3/06 6:15 PM Page 9 1 Getting to Know Bridge, Camera Raw, and Photoshop In This Chapter ᮣ Shooting raw images ᮣ Getting images to your computer ᮣ Viewing, organizing, and opening images in Bridge ᮣ Processing images in Camera Raw ᮣ Adjusting images in Photoshop CS2 emember the days (just a few years ago!) when digital photography con- Rsisted of having fun shooting photos, transferring them to your com- puter, and enhancing them using Photoshop? The choices were simple: shoot in JPEG or TIFF format. JPEG format is pretty good, but TIFF was supposed to be better (even though the resulting image files were huge). Before long, we figured out that JPEG quality was pretty close to TIFF quality; for the most part, shooting images in TIFF really didn’t offer much advantage. Discerning digital photographers have always wanted a file format that works like a digital equivalent of a traditional negative — giving the photographer total control overCOPYRIGHTED processing the image data captured MATERIAL by a digital camera. (Sure, you could skip the tweaking and leave it all up to the camera’s internal processing soft- ware — but why settle for blah results?) In the past few years, new digital camera models have delivered just that — the raw image format. The software that gives you control of those raw images is called (logically enough) Camera Raw. 05_774820 ch01.qxp 1/3/06 6:15 PM Page 10 10 Part I: Getting Your Feet Wet Shooting in the Raw Well, no, you don’t have to walk around wearing only your camera when you take photographs. I’m referring to shooting photos in the raw format with your digital camera. Today’s digital SLR and advanced compact cameras (also called prosumer because their features are in-between “pro” and “con- sumer”) can capture images in raw format, leaving the enhancements up to the digital photographer. That unprocessed image file — a digital negative — provides more artistic control. An example is the image shown in Figure 1-1. Unprocessed raw image Processed in Camera Raw and Photoshop CS2 Figure 1-1: Raw format gives photographers more creative control in processing images. Why raw? As a photographer, I shoot in raw format because it gives me better creative control over the image data captured by my digital camera. Raw format gives me an image file created exactly as the digital camera’s sensor captured it. I can adjust white balance, tint, brightness/contrast, and hue/saturation exactly the way I want. I don’t have to settle for what my digital camera’s firmware (built-in internal software) does to the image. As an added bonus, shooting images in raw format gives me a huge advan- tage over JPEG: I can correct nearly any incorrect exposure or off-kilter white balance I may have made while shooting. Don’t get me wrong, getting the cor- rect exposure and white balance is still just good photographic practice and well worth the effort — you have less tweaking to do later — but sometimes, when you’re out in the field taking photos and (say) that bright green UFO lands right over there, you may have to shoot first and ask questions later. Also, getting an accurate reading of the exposure is tricky if you’re simply squinting at the images you’ve just taken (and their tiny histograms) on your digital camera’s LCD screen — especially if you’re shooting outdoors on a 05_774820 ch01.qxp 1/3/06 6:15 PM Page 11 Chapter 1: Getting to Know Bridge, Camera Raw, and Photoshop 11 bright, sunny day. When you download those images to your computer and view them in Photoshop, you may discover that your image is either under- or overexposed. (It happens!) Raw format lets you use the capabilities of Photoshop to compensate for under- or overexposed photos without degrad- ing the quality of the image. It’s a nice backup if you ever need it. Not all raw files are the same Contrary to popular belief, not all raw images are the same; after all not all images — and not all cameras — are the same. The actual image data col- lected by a digital camera’s image sensor can vary noticeably from one manu- facturer to another; the electronics are different from model to model. For that reason, camera manufacturers offer their own proprietary software to process the raw images produced by their cameras. If you purchase (for example) a Nikon digital camera such as the model shown in Figure 1-2, and that model offers the ability to capture raw images, you can process those raw files with a proprietary pro- gram, either Nikon Picture Project or Nikon Capture (advanced raw- conversion software available at an additional cost). If you also own a Canon digital camera that produces raw images, however, you won’t be able to use Nikon’s software to process them. For those images, you have to use Canon’s proprietary soft- Figure 1-2: Newer advanced digital cameras ware, Digital Photo Professional — can capture images in raw format. but you can’t process Nikon images using Canon’s software. And if (like the pros) you also have other cameras by other makers . you get the idea. So did Adobe. That’s why Camera Raw exists. I detail the advantages and disadvantages (yes, there are some) of shooting raw images in Chapter 2. Though different camera manufactures have their own versions of “the” raw format, Photoshop CS2 provides a standard platform you can use to process just about any raw image, regardless of all that proprietary fuss. As an added bonus, Camera Raw can handle the whole process of adjusting and editing your raw images (called workflow) with no need to add other software pro- grams. (Imagine that — something about photography has actually become simpler!) Adobe provides a list of the digital cameras with which Camera Raw is compatible at http://adobe.com. (For more about workflow concepts, spin through Part IV.) 05_774820 ch01.qxp 1/3/06 6:15 PM Page 12 12 Part I: Getting Your Feet Wet Transferring Image Files to Your Computer If you’re already well versed in transferring images to your computer, feel free to skip to the next section. (I won’t even be offended. Honest.) If you’re still wrestling with transferring images from your camera to your computer, you can use any of several methods, but these two are the most common: ߜ Connecting your digital camera directly to your computer. When you first get your digital camera home from the camera store, you have to unpack all those manuals, CDs, and cables that come in the box. The CDs include a software utility used to transfer images to your computer; one of the cables is for plugging your digital camera into your computer so you can transfer the images. (Refer to your camera’s owner’s manual to figure out which connection on the camera to plug the cable into. The other end of the cable connects to your computer’s FireWire or USB port.) ߜ Using a card reader. The fastest way to download images to Figure 1-3: Card readers are the fastest, safest your computer is to use a card way to download images to your computer. reader. Card readers (such as the one shown in Figure 1-3) are devices that plug into your computer’s USB port or (with some models) the faster FireWire port, providing an efficient way to transfer images — often from various cards with differ- ent formats such as Compact Flash, SD (secure digital), or memory stick. Using a card reader to download images to your computer also offers added security. With a direct connection, there’s often the worry that your digital camera’s battery might go dead while the image transfer is going on. A card reader can be especially reassuring if you have a large batch of images to transfer, and want it to happen correctly the first time. To download images to your computer, follow these steps: 1. Determine where you want the downloaded images to go on your computer. If you’re a Windows user, the easiest place to put your downloaded images is in the My Pictures folder (opened by choosing My Computer➪ My Pictures). You can also create a new folder to hold your images. (More information on image management and creating image folders can be found in Chapter 4.) On a Mac running OS X, the Pictures folder is a convenient location for downloading your images to. 05_774820 ch01.qxp 1/3/06 6:15 PM Page 13 Chapter 1: Getting to Know Bridge, Camera Raw, and Photoshop 13 2. Plug your digital camera into the computer, using the supplied USB or FireWire cable. Before you connect, make sure your digital camera is turned off. If you are using a card reader, make sure it’s plugged into an available USB or FireWire port on you computer. 3. Turn on your digital camera or insert a card into your card reader. Turning on your digital camera will automatically start the downloading process on your computer. If you’re using a card reader, inserting a memory card into the card reader starts the downloading process automati- cally. Your computer recognizes the digital camera or card reader as an external device and displays the window shown in Figure 1-4. 4. Copy images to your computer. Choose to open your folder, Figure 1-4: After your computer automatically using Windows Explorer as recognizes your digital camera, you can shown in Figure 1-4.

  • Hardware and Software for Panoramic Photography
    ROVANIEMI UNIVERSITY OF APPLIED SCIENCES SCHOOL OF TECHNOLOGY Degree Programme in Information Technology Thesis HARDWARE AND SOFTWARE FOR PANORAMIC PHOTOGRAPHY Julia Benzar 2012 Supervisor: Veikko Keränen Approved _______2012__________ The thesis can be borrowed. School of Technology Abstract of Thesis Degree Programme in Information Technology _____________________________________________________________ Author Julia Benzar Year 2012 Subject of thesis Hardware and Software for Panoramic Photography Number of pages 48 In this thesis, panoramic photography was chosen as the topic of study. The primary goal of the investigation was to understand the phenomenon of pa- noramic photography and the secondary goal was to establish guidelines for its workflow. The aim was to reveal what hardware and what software is re- quired for panoramic photographs. The methodology was to explore the existing material on the topics of hard- ware and software that is implemented for producing panoramic images. La- ter, the best available hardware and different software was chosen to take the images and to test the process of stitching the images together. The ex- periment material was the result of the practical work, such the overall pro- cess and experience, gained from the process, the practical usage of hard- ware and software, as well as the images taken for stitching panorama. The main research material was the final result of stitching panoramas. The main results of the practical project work were conclusion statements of what is the best hardware and software among the options tested. The re- sults of the work can also suggest a workflow for creating panoramic images using the described hardware and software. The choice of hardware and software was limited, so there is place for further experiments.

  • Understanding Image Formats and When to Use Them
    Understanding Image Formats And When to Use Them Are you familiar with the extensions after your images? There are so many image formats that it’s so easy to get confused! File extensions like .jpeg, .bmp, .gif, and more can be seen after an image’s file name. Most of us disregard it, thinking there is no significance regarding these image formats. These are all different and not cross‐ compatible. These image formats have their own pros and cons. They were created for specific, yet different purposes. What’s the difference, and when is each format appropriate to use? Every graphic you see online is an image file. Most everything you see printed on paper, plastic or a t‐shirt came from an image file. These files come in a variety of formats, and each is optimized for a specific use. Using the right type for the right job means your design will come out picture perfect and just how you intended. The wrong format could mean a bad print or a poor web image, a giant download or a missing graphic in an email Most image files fit into one of two general categories—raster files and vector files—and each category has its own specific uses. This breakdown isn’t perfect. For example, certain formats can actually contain elements of both types. But this is a good place to start when thinking about which format to use for your projects. Raster Images Raster images are made up of a set grid of dots called pixels where each pixel is assigned a color.

  • The Musk Duck Photography Special
    The Musk Duck Photography Special Compiled by Ian Ashton November 2020 Chaffinch 1977 UK England, Mamiya SLR and 135mm prime lens with extension tubes. Ian Ashton Here we are in November 2020 and most of Birdlife Ballarat’s planned syllabus meetings and outings have been cancelled including this year’s photography competition due to the Pandemic. I was to give a talk back in June, it was titled, ‘How times have changed’, an old-fashioned slide show. So, in place of that and to acknowledge that some of our members are not just bird watchers, this Musk Duck photography special was conceived. Birdlife Ballarat does not have a dedicated photography group, but many members do own cameras. It may be that in these uncertain times some members have contemplated buying a camera or upgrading their equipment or their knowledge. I thought it would be good to share some ideas and techniques. Left, my very first SLR was a Mamiya 500 like this one. The 500 related to the shutter speed, 1,500th of a second. My present camera can take photos at 1,4000th Of a second. Times and technology have changed. MD Photo Special Birdwatching and bird photography do not always sit well together, but of course most birdwatchers enjoy seeing photographs of birds. At one end we have the birdwatcher and at the other end the photographer and between these two ends there are as many combinations of the two as you can imagine. The best bird photographers know their subject and can have immense amounts of knowledge and patience to achieve the outcome they are aiming for.

  • Which Image Format
    CASE STUDY Which Image Format PNG PNG (Portable Network Graphics), an extensible file format for the lossless, portable, well-compressed storage of raster images. PNG provides a patent-free replacement for GIF and can also replace many common uses of TIFF. Indexed-color, gray scale, and true color images are supported, plus an optional alpha channel. Sample depths range from 1 to 16 bits. However, the format is not widely supported in common image programs. AVI AVI stands for Audio Video Interleave and is currently the most common file format for storing audio/video data on the PC. AVI’s are 8-bit per image plane. This file format conforms to the Microsoft Windows Resource Interchange File Format (RIFF) specification, which makes it convenient for sharing the image sequence between computers. AVI files (which typically end in the .avi extension) require a specific player that supports. RAW A RAW image format contains minimally processed data from the image sensor. RAW literally means unprocessed or uncooked. RAW images must be processed and converted to RGB format if it is a color image. Photron however, does not limit RAW as a unprocessed image. The “Bayer” check box must be selected to save the RAW image as an unprocessed image. RAW images have 8-bits per image plane. RAWW A RAWW image format contains minimally processed data from the image sensor. RAWW images must be processed and converted to RGB format if it is a color image. Photron however, does not limit RAWW as a unprocessed image. The “Bayer” check box must be selected to save the RAWW image as an unprocessed image.

  • A Review of Oculoplastic Photography: a Guide for Clinician Photographers
    Open Access Review Article DOI: 10.7759/cureus.733 A Review Of Oculoplastic Photography: A Guide For Clinician Photographers Chin T. Ong 1 , Jun Fai Yap 2 , Yong Zheng Wai 2 , Qi Xiong Ng 2 1. Ophthalmology, Beacon International Specialist Hospital 2. Ophthalmology, University of Malaya Corresponding author: Chin T. Ong, [email protected] Abstract Clinical photography in the field of oculoplastic surgery has many applications. It is possible for clinicians to obtain standardized clinical photographs without a studio. A clinician photographer has the advantage of knowing exactly what to photograph as well as having immediate access to the images. In order to maintain standardization in the photographs, the photographic settings should remain constant. This article covers essential photographic equipment, camera settings, patient pose, and digital asset management. Categories: Medical Education, Ophthalmology Keywords: clinical photography, standardization, oculoplastic surgery Introduction And Background Clinical photographs are useful for clinical records, research, audit, education, and in supporting medico- legal cases [1-3]. Standardized clinical photographs are often taken by medical photographers using professional grade photographic equipment in dedicated studios. However, it is possible for clinicians to obtain high quality clinical photographs using simpler photographic equipment outside a studio [4]. There are many benefits if a clinician takes patient photographs. The clinician photographer knows without instructions exactly which area of the body to photograph. The photographic session can take place during the patient consultation with no further delays for the patient [1]. The images are instantly available to the clinician and can be shown to the patient during the consultation process. Standardization The most important concept in oculoplastic photography is standardization [1, 4-5].
