20/20 Color MD is a Photoshop Plugin that is designed for photographers,
artists and graphic designers who want great looking images, but would
rather not sit in front of a computer all day.

New 20/20 Version 2.0

If you liked the original 20/20 Color MD, you are going to absolutely love
version 2. Last year, when we started working on a new release, we rethought
everything, redesigned everything, and then rewrote 20/20 from the ground
up. We are confident that 20/20 will instantly become your favorite
Photoshop production tool.

New features include 16 bit compatibility; an all new 6-step Wizard with
user defined control on every step; new vastly improved Snapshot function;
and new color correction algorithms. Plus, there are a host of new tools,
new interface shortcuts, and much more. But, with all these added features,
we worked just as hard to make 20/20 Color MD easier, faster, and more
enjoyable.

Now Photoshop CS3 Compatible
