I discussed the concept of Infinity Masks and the Zone-PickerTM in a blog post in October 2015. Shortly afterwards I began collaborating on a project that uses a Photoshop plug-in dedicated to implementing this concept more fully. The plug-in provides a unique method of making masks. It uses its own equations, instead of Photoshop calculations, to determine which tones are included in a mask. By changing the variables in the equations the resultant mask can be infinitely defined and adjusted.
The way to use this plug-in is the TK Infinity Mask panel shown below. The buttons and sliders on this panel change the variables in the plug-in's equations and the mask is quickly updated so the user sees the results. The plug-in/panel can make masks based on image luminosity, or it can use data from the red, green or blue channels as the starting point. It can even make saturation and vibrance masks by extracting this information from the image's pixels.
Decision making for the panel is completely mask-based. The user views the actual mask that is being created and changes it as they manipulate the controls on the panel. It's normally a very fast process once the necessary merge-visible layer has been created. Seeing the mask and being able to directly adjust it provides a more real-time experience. Once satisfied, output buttons at the bottom provide options for using the mask to continue developing the image. Complete information about the panel is in the Instructions PDF . There is also a video at the bottom of this page by Sean Bagshaw that provides an overview of the panel.
While not identical since they are constructed by a different method within the plug-in, Infinity Masks share the same characteristics and work the same as luminosity masks:
A couple of other important things to know about the TK Infinity Mask panel:
Where to Get It
The TK Infinity Mask panel is available on the Panels & Videos page. It is one component of the two-panel package that includes the CC version of the TK Actions V4 panel . Sean Bagshaw has recorded four videos on how to install and use the panel, and these are also included in the download. (NOTE: Previous CC customers will be provided options to update their package to add the TK Infinity Mask panel in the near future. Watch your email.)
I've also worked with André Distel to prepare a German version of the Infinity Mask panel. It's available on André's Website .
The speed at which the masks are generated and the flexibility in creating them will make the TK Infinity Mask panel valuable in many masking situations. I hope you'll give it a try. Please feel free to contact me if you have any questions.
