Voila is a slick screenshot tool with a powerful ability to capture just about anything on your screen. Its slick interface has been considerably improved in recent versions, with features added such as blurring, iSight integration, Flickr support and screencast editing.
Voila can capture any shape, such as Circular, Polygonal, Triangular, or Freehand objects. You've also got standard capture tool options, such as Menu Capture, Fullscreen Capture, Object Capture, Rectangular Capture and a Timed Capture as well. A lot of effort has gone into integrating Voila with other image applications and sites and so you can send and open files from iPhoto and Flickr. Voila is also integrated with Mail if you want to send your screen grabs immediately.
Voila features all the standard options you expect from a screen capture tool, including annotation tools that allow you to add text, arrows, lines, crop and even add watermarks. There are a few filters too, including blurred, torn and framed edges. Exporting from Voila can be done to PNG, JPEG, TIFF, PDF, GIF and BMP formats.
The overall accessibility of Voila is what impresses the most. Easily accessible from either the menu bar or Dock, your hand never needs to leave the mouse to reveal it. Added to the fact that recent captures are easily visible along the bottom of the interface, you're never left searching your hard drive for captures.
The most recent useful addition to Voila is the ability to trim screencasts using QuickTime. The editing features could do with a little extending but it's sufficient for basic cutting.
If you've got a steady hand, Voila allows you to grab objects that would otherwise be limited to the square or rigid capture parameters of most general screen capture apps. An excellent screen capture application that's come a long way in a short time.
