"PercepTool" adjusts the look of images so as to mimic the human brain's own processes, based on an idea prompted by Polaroid's Dr. Edwin H. Land. Released for both Windows and Mac OS X systems, Perceptool works in concert with either Adobe Photoshop CS3 or CS4.
Today, a new version of PercepTool has been released which brings a significant improvement in processing speed. We understand that PercepTool v1.5.5 offers speeds about eight times faster than the previous release. It is also said to correct a downloading problem on Windows Vista machines.
As with the previous version, the PercepTool plugin's script can operate in 32-bit mode only in Photoshop CS4 Extended due to limited support for 32-bit mode layers in the standard version. Users of Photoshop CS4 Standard can use the script in 8-bit or 16-bit modes, and can use 32-bit mode by applying the plugin alone, without using the script.
A few examples of the results to be obtained from the initial release of PercepTool can be seen below, and a 30-day trial version is available for download if you'd like to try the plugin for yourself. The cost to purchase is approximately $90, on either the Mac or Windows platforms.
