![]() ![]() When you upload a photograph to Flickr, some of that Exif data is automatically recognized by Flickr - you'll see it when you look at your photograph under a link called "more properties" which will be right under the "Taken with a." information. Sometimes information about the lens and shutter speed and other exposure conditions is stored, and whether or not the flash was fired. ![]() The mode your camera was in is usually stored (such as 'auto' or 'sports' or 'macro'), and the width and height of the photograph in pixels is there too. Well, for starters, the camera brand and model is usually stored, as well as the time and date the photograph was taken. Metadata in an image file is often stored in a format called "Exif," which is an acronym for "Exchangeable image file format." What kind of data is stored in Exif? We call data that is about data, 'metadata'. But buried within the image file is information about the photograph. Most of it is indeed picture data - pixels, colors, and that sort of thing. When you see a photographic image on your computer's screen, not all of the data contained in the image file is visible. ![]()
