Our release of the ColorPerfect plug-in for Adobe Photoshop rendered GamSat 1.0 mostly obsolete
GamSat 1.0 is a plug-in for Adobe Photoshop that was used to change the Gamma, saturation and / or hue of an image. Our release of the ColorPerfect plug-in for Adobe Photoshop as the successor of our original ColorNeg and ColorPos plug-ins rendered GamSat mostly obsolete, too. GamSat is still available as an unlimited 30 day trial version and can be permanently activated with any ColorPerfect license key.
Supported versions of Adobe Photoshop, PhotoLine and Adobe Photoshop Elements for PC & Mac
On Windows PCs one or both of the 32 and 64 bit plug-in versions of ColorPerfect can be used with Adobe Photoshop 7 through CS6 as well as Adobe Photoshop CC, CC 2014, CC 2015 and CC 2017. PhotoLine can also be used as a host. It is fully supported from its release 16 onwards. The third host you may use is Adobe Photoshop Elements (PSE) in its versions 2 through 15. For installation instructions detailing what to install where please refer to ColorPerfect's PC ReadMe file. Note that 64 bit hosts exclusively work with Colorperfect and not with our legacy plug-ins.
On Intel Macs using Mac OS X one or both of the 32 and 64 bit plug-in versions of ColorPerfect can be used with Adobe Photoshop CS3 through CS6 as well as Adobe Photoshop CC through CC 2017. PhotoLine can also be used as a host. It is fully supported from its release 16 onwards. The third host you may use is Adobe Photoshop Elements (PSE) in its versions 6 through 15. For installation instructions detailing what to install where please refer to ColorPerfect's Intel Mac ReadMe file. Note that 64 bit hosts exclusively work with Colorperfect and not with our legacy plug-ins.
On actual legacy PowerPC Mac hardware Adobe Photoshop 7, CS, CS2, CS3 and CS4, PhotoLine 15 through 17.10 and Adobe Photoshop Elements 2 through 6 are supported for both ColorPerfect and our legacy plug-ins. For installation instructions detailing what to install where please refer to ColorPerfect's PPC Mac ReadMe file.
ColorPerfect, ColorNeg, ColorPos and GamSat can all be unlocked with the same license key
Prior to the release of ColorPerfect we provided three separate plug-ins for Adobe Photoshop: ColorNeg, ColorPos and GamSat. These were replaced by ColorPerfect in 2010. We still offer the old plug-ins along with their original PDF manuals for download. The articles we previously published on GamSat were transformed into a subsection of the ColorPos category of this web site.
The same license key can be used to unlock our international English plug-ins ColorPerfect, ColorNeg, ColorPos and GamSat for the chosen operating system. A license costs $67.00. If you are located within the European Union that is a net price and the VAT rate applicable for your purchase will be added to that during checkout. To use the plug-ins both under Windows and under Mac OS X separate licenses are required. The license keys of the German versions are not compatible. The links to the secure shop of our distribution partner can be found below the downloads in the right hand side column of this web site.
Grid in the demo plug-in versions
This web site offers fully functional demo versions of the international English plug-ins. The demo plug-in versions of ColorPerfect, ColorNeg and ColorPos generate a grid in the final image. The grid is subtle enough that the results can be evaluated and will go away once you enter your license key which can be purchased via a secure web page as detailed above.
Old plug-ins, PDF manuals and ColorPerfect's built-in help system
Instead of a printable manual ColorPerfect currently features a built-in help system. Users who are familiar with the original ColorNeg or ColorPos plug-in will quickly get acquainted with ColorPerfect. Mastering ColorPerfect by means of the old manuals will likely be more confusing than helpful, so we ask new users to resort to the plug-in's help system right away. To do so please follow the instructions in ColorPerfect's ReadMe.txt file, load the linear scan of a negative or a Tiff file created by MakeTiff from a digital RAW photo in Photoshop, start the plug-in and immediately click on the Help button. Follow the order suggested to read the help texts where applicable.
