I have 3 images all associated with each other. Image 'A' is made from images 'B' and 'C'. The three images were actually rendered in 3DS MAX as elements.
So in photoshop image 'B' multiply(blend mode) image 'C' = image 'A' then image 'A' divide(blend mode) image 'B' = image 'C'.
Is blend mode 'multiply' actually multiply? Which blend mode represents dividie?
Thanks in advance.

Maybe overlay or screen would be closer to what you want. If you would like to see how the blend modes work. Create a layer with black, 50% grey, and white on it. Duplicate the layer and invert it. This will flip the colors the opposite direction. Now with the top layer selected try the multiple, overlay and screen modes. While your at it go through the rest. On a PC when one blend mode has been selected you can use the up and down arrow keys to scroll through the modes.

Since these objects were rendered in a 3d program, each object may have its own alpha. This can usually be accomplished by hiding the remaining objects from the camera. Once rendered use a format that supports the alpha channel. Then the objects should beable to overlay each other without the use of the blend modes.

To understand the math involved better, you might want to try your experiments using images that are in LAB mode rather than RGB.

Thanks Silkrooster. The little experiment helped a lot understanding what is going on.
Michael, unfortunately LAB's not a format available in 3DS MAX. But I was able to figure things out.
Thanks both of you for the help.
