Channels combine additively, while layers combine subtractively (in normal mode). Is this true?
I appreciate that channels and layers have different intents and applications. However as part of trying to understand the differences between channels and layers, I attempted to simulate channels, and their functions, in Photoshop Elements, by using layers. Not sensible, I realize but I’m a curious sort of person. Anyway, for a given image, it is easy to create layers in PSE that look just like the R, G and B channels in PS.
But when trying to combine the R, G and B layers in PSE (using "normal"mode) it clearly doesn’t "work". My tentative conclusion is that channels (in PS) combine additively while layers (in PSE) combine subtractively.
Am I right or just confused? Any words or links to educate me or clarify my thinking will be appreciated.
