Photoshop has a whole bunch of different blend modes but knowing what they all do… Well, even many of the most advanced Photoshop users don’t know what they all do. That not knowing could be holding you back, though. And this video is a perfect example as to why.
I’ve been using Photoshop since about Version 3.0 (yes, I’m that old), but I don’t recall ever once using the “Divide” blending mode. After watching this video from Unmesh at PiXimperfect, though, I wish I’d started looking into it years ago. Unmesh starts by showing how it works in a practical sense, and then explains the underlying maths behind it to help you understand how it does what it does.
