Paint.net

Paint.net is free photo and image operation application for the Windows platform. Every characteristic of Paint.net, including the user interface, was designed to be right away intuitive and easy to learn without assistance.

Some characteristics Include:

1.     Extraordinary effects tools include: distortion, noise blurring, sharpening, red-eye removal as well as embossing.

2.     3D Rotate/Zoom effects make it very easy to add perspective and tilting.

3.      Picture manipulation tools include: saturation, curves, brightness, contrast, hue, and levels. You can also convert an image to black and white, or sepia.

To navigate multiple images simply, Paint.net uses a tabbed document boundary. The tabs show a live thumbnail of the image in place of a text description.
