Metadata is the term that describes information that is embedded inside of your images. When you take a photograph with your digital camera, that camera imprints in a little secret file information about the exposure and when it was taken and all kinds of good stuff. Currently, I'm in the Adobe Bridge and I have an image selected of a meal that I cooked. Yes, I can cook, I guess, kind of. But if I want to see information about this particular file, I can look over here in the Metadata Panel and just get some basic information, such as the size as far as pixel dimension and the space as far as color. So I have RGB here as far as red, green and blue. And what I can also do is go to a focused view in the Bridge under the Window Menu, under Workspaces, called Metadata Focus. This will allow me to see the metadata of the file I have selected and the other files in this particular folder and I can see that this is the name of the image that the camera put there, the date I took the photograph, if and when I modified it, the document type, which is a JPEG and the camera settings and once again, the color space. So that only a little bit of metadata information and I know you're probably thinking there can't be more. Yes, there can be. What we can do now is right click on this photograph or any photograph you happen to have open and choose File, Info. A gigantic sheet slides down and you can see that you can put a whole bunch of information that will be saved with the file. So you can put the document title, the author, the author title, a description, the description writer, keywords, copyright status, which is pretty important. You want to copyright your work, especially now with this whole Orphan Acts thing going on in Congress. So check the Internet out about that information if you want to find out what they're planning to do about copyrighted work. Let's see. I'll give you a brief summary. If they can't find you as the author, then they're going to try to put it into the public domain or have it floating around there so anybody can grab it. So definitely copyright your work. Also you can check out the Library of Congress. Just do a search for copyright forms and go on the Internet or call Washington DC and get the number for the Library of Congress. Copyrighting your work; very, very, very, very important. You can also find other information here: Illustrator, Adobe stock photos, contact information, camera data, camera data 2, categories, history. There's just so much stuff here but once again, this is all actually embedded inside the file, which is good. You can pull it up at all times. So what is the real practical purpose of metadata? Well, in the case of keywords, you can use these to help you find a file quickly. So you can put Family Vacation or Baltimore or New York City or whatever and then do a search based on those parameters. So that's what metadata is. Once again, files that are actually embedded with this information that can tell you all kinds of information from the author of the photograph to the camera to the camera information.
