Reference info for blend modes

[Jerelo]

Can anyone point me to a reference for what various blend modes do? For example, what are the operations in executing an overlay blend? This might be something developers access from Apple, or as article about art studio, or even a science article. Hoping for specific technical descriptions of each blend mode, especially overlay.

Here's a description of blending modes from A Certain Other Painting Program. It's as clear a description of the various processes as it's possible to be and it STILL isn't very.

You might keep this open in your browser and toggle between the explanation and an open artstudio file, trying each mode and comparing the effect with the description until it clicks for you.

FWIW, some of the terms - e.g., Burn and Dodge - come from photography developing and printing and, since that Certain Other Program was originally intended for photographers and printing production people, they kept the names that the intended audience was familiar with. So you could probably look at a book on photography and darkroom techniques and see what they used to be about IRL.

Hope this helps.
