Digital Still Camera Image File Format Standard
Digital Still Camera Image File Format Standard (Exchangeable image file format for Digital Still Cameras: Exif) Version 2.1 June 12, 1998 Japan Electronic Industry Development Association (JEIDA) This standard makes no warranty, express or implied, with respect to the use of any intellectual property, such as patents, copyrights and trademarks, belonging to any corporation or individual. Nor does this standard make any warranty regarding system reliability or product liability. Windows™ is a registered trademark of Microsoft Corporation in the United States and elsewhere. FlashPix™ is a registered trademark of Eastman Kodak Company. Revision History This "Digital Still Camera Image File Format Standard" is issued as a standard for the image file format (Exif: Exchangeable image file format) used in digital still cameras and related systems. It was first published in October 1996 as Version 1.0i. Then in May 1997, Version 1.1ii was issued, adding specifications for optional attribute information as well as stipulations relating to format implementation, in addition to the mandatory specifications of Version 1.0. The desire for a uniform file format standard for the image data stored by digital still cameras has increased as these cameras have grown in popularity. At the same time, with the broadening application of this technology, a similar desire has arisen for uniformity of the attribute information that can be recorded in a file. The Version 2.0iii makes improvements to the Exif format for greater ease of use, while allowing for backward compatibility with products of manufacturers currently implementing Exif Version 1.x or considering its future implementation. -
What Resolution Should Your Images Be?
What Resolution Should Your Images Be? The best way to determine the optimum resolution is to think about the final use of your images. For publication you’ll need the highest resolution, for desktop printing lower, and for web or classroom use, lower still. The following table is a general guide; detailed explanations follow. Use Pixel Size Resolution Preferred Approx. File File Format Size Projected in class About 1024 pixels wide 102 DPI JPEG 300–600 K for a horizontal image; or 768 pixels high for a vertical one Web site About 400–600 pixels 72 DPI JPEG 20–200 K wide for a large image; 100–200 for a thumbnail image Printed in a book Multiply intended print 300 DPI EPS or TIFF 6–10 MB or art magazine size by resolution; e.g. an image to be printed as 6” W x 4” H would be 1800 x 1200 pixels. Printed on a Multiply intended print 200 DPI EPS or TIFF 2-3 MB laserwriter size by resolution; e.g. an image to be printed as 6” W x 4” H would be 1200 x 800 pixels. Digital Camera Photos Digital cameras have a range of preset resolutions which vary from camera to camera. Designation Resolution Max. Image size at Printable size on 300 DPI a color printer 4 Megapixels 2272 x 1704 pixels 7.5” x 5.7” 12” x 9” 3 Megapixels 2048 x 1536 pixels 6.8” x 5” 11” x 8.5” 2 Megapixels 1600 x 1200 pixels 5.3” x 4” 6” x 4” 1 Megapixel 1024 x 768 pixels 3.5” x 2.5” 5” x 3 If you can, you generally want to shoot larger than you need, then sharpen the image and reduce its size in Photoshop. -
Invention of Digital Photograph
Invention of Digital photograph Digital photography uses cameras containing arrays of electronic photodetectors to capture images focused by a lens, as opposed to an exposure on photographic film. The captured images are digitized and stored as a computer file ready for further digital processing, viewing, electronic publishing, or digital printing. Until the advent of such technology, photographs were made by exposing light sensitive photographic film and paper, which was processed in liquid chemical solutions to develop and stabilize the image. Digital photographs are typically created solely by computer-based photoelectric and mechanical techniques, without wet bath chemical processing. The first consumer digital cameras were marketed in the late 1990s.[1] Professionals gravitated to digital slowly, and were won over when their professional work required using digital files to fulfill the demands of employers and/or clients, for faster turn- around than conventional methods would allow.[2] Starting around 2000, digital cameras were incorporated in cell phones and in the following years, cell phone cameras became widespread, particularly due to their connectivity to social media websites and email. Since 2010, the digital point-and-shoot and DSLR formats have also seen competition from the mirrorless digital camera format, which typically provides better image quality than the point-and-shoot or cell phone formats but comes in a smaller size and shape than the typical DSLR. Many mirrorless cameras accept interchangeable lenses and have advanced features through an electronic viewfinder, which replaces the through-the-lens finder image of the SLR format. While digital photography has only relatively recently become mainstream, the late 20th century saw many small developments leading to its creation. -

The proposed pixel design effectively increases the FWC without inducing overflow of photo-generated charge in a limited pixel area. An MOS capacitor is integrated in a pixel and accumulated charges in a photodiode are transferred to the in-pixel capacitor multiple times depending on the maximum incident light intensity. In addition, the modulation transfer function (MTF) and radiation damage effect on the pixel, which are especially important for space applications, are studied and analyzed through fabrication of the CIS. The CIS was fabricated using a 0.11 µm 1-poly 4-metal CIS process to demonstrate the proposed techniques and pixel design. A measured FWC of 103,448 electrons and MTF improvement of 300% are achieved with 6.5 µm pixel pitch. Keywords: CMOS image sensors; wide dynamic range; multiple charge transfer; space applications; radiation damage effects 1. Introduction Imaging devices are essential components in the space environment for a range of applications including earth observation, star trackers on satellites, lander and rover cameras [1]. -

Getting the Right Gear
Chapter 1 Getting the Right Gear In This Chapter ▶ Picking the right camera for the job ▶ Complementing your camera with accessories ports and action photography is like most things in Slife — if you want to be the best at it, you need to have the best gear. Luckily for you, lots of options are available when determining the best gear based on your level of experi- ence and expertise. In this chapter, I help you determine what you’re going to need — including what type of camera and any necessary accessories — based on what you plan on photographing and how comfortable you are behind the lens. The Internet contains a wealth of information, but nothing beats asking other photographers what they’re using. You can share in their camera jubilation or avoid the same pitfalls that they fell into by purchasing that “bargain” point-and-shoot camera that didn’t turn out to be such a bargain after all. ChoosingCOPYRIGHTED the Best Camera MATERIAL for the Job at Hand Whether you’ll be taking photographs at your daughter’s soccer game or trying to make a career out of sports photography, having the right camera for the situation will make all the difference. In the past, very few affordable cameras could capture action as well as the pro’s gear.

More About Digital Cameras Image Characteristics Several Important
More about Digital Cameras Image Characteristics Several important characteristics of digital images include: Physical Size How big is the image that has been captured, as measured in inches or pixels? File Size How large is the computer file that makes up the image, as measured in kilobytes or megabytes? Pixels All digital images taken with a digital camera are made up of pixels (short for picture elements). A pixel is the smallest part (sometimes called a point or a dot) of a digital image and the total number of pixels make up the image and help determine its size and its resolution, or how much information is included in the image when we view it. Generally speaking, the larger the number of pixels an image contains, the sharper it will appear, especially when it is enlarged, which is what happens when we want to print our photographs larger than will fit into small 3 1\2 X 5 inch or 5 X 7 inch frames. You will notice in the first picture below that the Grand Canyon is in sharp focus and there is a large amount of detail in the image. However, when the image is enlarged to an extreme level, the individual pixels that make up the image are visible--and the image is no longer clear and sharp. Megapixels The term megapixels means one million pixels. When we discuss how sharp a digital image is or how much resolution it has, we usually refer to the number of megapixels that make up the image. One of the biggest selling features of digital cameras is the number of megapixels it is capable of producing when a picture is taken. -
