SnapCrab for Windows is a powerful tool for taking screen captures with tons of options to customize.
If you do a lot of web tutorials or reviews (like we do), then a screen capture program is a must. By default, Windows requires you to hit print screen and paste the image into an editor like Microsoft Paint or Adobe Photoshop. Programs like SnapCrab and Snagit provide a more elegant solution with powerful capturing tools.
SnapCrab for Windows has the ability to snap the entire screen, a single program, or a single window. It also allows you to take captures with transparent or colored backgrounds. SnapCrab for Windows includes many different customization options, like defining your own hot keys and modifying how the program takes snapshots. Another feature we really enjoyed was SnapCrab for Windows' ability to give us HTML color codes of anything on the screen.
Unfortunately, SnapCrab for Windows doesn't include an editor so the captures you take will have to be thrown into a secondary app for modification. However, sharing captures is easy as it integrates with Facebook, Twitter, and Evernote for quick sharing within the app.
While SnapCrab for Windows is not nearly as easy to use as Snagit, it is certainly the right price (free!) and offers a much more elegant screen capturing experience than Window's default method.
