Metadata is a set of information that is written to the EXIF file header of every digital image.
How's that? Let's try again, in English: Digital cameras automatically record bits of data--camera model, exposure settings, lens focal length, etc., plus ordinary things like date and time--and save them with the image. It's the information that travels with every digital image you make.
You can read some of this information if you allow your mouse pointer to hover over the image file while in Windows Explorer. Or you can read most of it in Adobe Photoshop by selecting File Info from the File menu.
Until now, it's been difficult to review or revise this metadata. Thanks to a free Microsoft application called Photo Info, you can easily browse and edit the information. Right click an image and choose Photo Info from the menu. A tabbed box will appear.
You can add your name as author, automatically generate a Copyright notice, and perform various other functions. This is a must-have application for serious photographers who use the windows operating system--and it's free.
