The Battle of the Screen Capture Programs
I spent a little time exploring two screen-capture software packages and found out that on the surface, they're a lot alike. Both programs offer the garden variety of formats for saving screen captures (BMP, GIF, JPEG, TIFF, and TGA), and in both cases special tools for optimizing output are available. For example, when saving an image as a bitmap (BMP) using either program you can select a bit depth anywhere between one and 32.
