Techsmith SnagIt is a very easy and comprehensive tool to capture anything you see on the screen. You can then amend and combine the taken screen shots. The best part of this application is the option to directly share the screenshots with your friends, buddies, family members via email, IM, etc. In old days, first we used to take the screenshot, save it, edit it and then share it. SnagIt made it easier by simply taking a screenshot, edit it and sharing it.
