“The Joy of Editing” is a YouTube channel run by Dave Kelly, and he recently uploaded a video featuring luminosity masks and the TK7 Go module. He explains the basic features of how to use it, and photographers familiar with the panel may already know some of what he demonstrates. However, he does make especially good use of the module’s Zone masks in this video. Zone masks were completely changed in the Go module compared to the Zone masks in the RapidMask module, and they’re possibly underutilized. Dave uses them as layer masks on Curves adjustment layers, but I also find them useful for burning and dodging after loading them as a selection. If you’ve not experimented the Zone masks in the Go module, hopefully seeing what Dave does in this video will provide some incentive and confidence to give them a try.
