Blend Mode Math, CHOPs etc.

A while back Doug asked on the Adobe forums about deeper info on the blend modes found in Photoshop, including the new ones found in v7.

Although this link does not cover Photoshop, many blend modes are explained in further detail. It also has a primer on the basics of imaging too. Although a Deneba Canvas tutorial, it is applicable to many other image editors:

More on channel mixer, calculations and apply image can be found at this link (scroll down a bit):

The 'bible' on this topic is an old book called 'Photoshop Channel CHOPs'. The old Kai's Power Tips on CHOP's can also be considered to be ground breaking as well when it comes to inter-channel math.

Can anyone else add good links or further sources of deeper info on the blending modes, including the new ones of v7.

Stephen, thanks for the chops link -- I've owned "Channel Chops" for a couple of years, and am just getting to where I'm understanding a good deal of it. This link is an easier read.

Here's one link that could help:Ben Willmore - Blending modes

and a link to an Adobe pdf on the subject:
Adobe -- become a layer blending expert

Hi CJ, and thanks for the addition to this thread.

To keep the ball rolling, here is a complex layer blending mode 'actorial' which seems to work as intended with Photoshop 6 but does not seem to work right in v7 (but I could be doing something wrong).

This is not my action, just an Adobe Exchange d/load I did becuase I did not know what an actorial was...(think of a tutorial combined into an action).

Stephen,

I also downloaded that action, and I'm using Photoshop 7. No luck here either. Thanks for the other links.
