TNT Screen Capture is a good capture application, with all the necessary tools to capture, edit and save your screenshots. Even though the interface seems a bit stuffy, you quickly get used to the placement of each toolbar: the top one is for actions, right for editing and left for capture options.
TNT allows you to capture a free or fixed region and can create thumbnails. We like the dozen or so effects you can add to your screenshots and, although the editing tools are pretty basic, they'll get the job done.
The 3D perspective is more of a gadget than anything.
TNT Screen Capture has everything you need to take a picture of your screen and edit it.
It provides lots of helps and tips are easily available, which help you understand the crowded interface a bit more. Although the program could have been designed a bit better, it does what you'd expect of it.
