NOTE: The TK7 plugin for Photoshop is no longer available now that the TK9 plugin for Photoshop has been released. Please visit the TK9 plugin page for the latest info on this newer version. You can purchase the TK9 plugin and instructional videos on the Panels & Videos page
The TK7 panel is the newest release of the comprehensive panel for making luminosity masks and running Photoshop. It's now had two major updates. One in September 2019 and again in July 2020. Like its predecessor, the TK7 panel is modular, so users can configure it in whatever manner works best in their workspace. The Combo/Cx module even has two different arrangements to allow a new compact layout if that's desired. (Sean Bagshaw has a video at the bottom of this page that shows how to do this.) TK panels are used worldwide and come pre-programmed with six common languages: English, Spanish, German, French, Italian, and Chinese. Users can choose the language they prefer. The TK7 panel works equally well on Mac and Windows computers and installs in Photoshop CC 2014 through Photoshop 2020.
The main feature of the TK7 panel is its ability to make pixel-based masks, like luminosity masks. But luminosity masks are really just the beginning. TK7 also makes masks based on color channels, hue (Infinity Color masks), saturation, vibrance, and even the user's own alpha channels. The latest update has the new "Go" module for doing this. It's demonstrated in the video below. The Go module displays masks at near real-time speeds, and it has a dedicated 16-bit workflow to ensure the best possible masks from creation through deployment.
