That's cool, but you only get grayscale output.

Split Channels is one of those features I seem to have forgotten about! I can see that it could be useful for B&W conversions but wish it did not automatically close down the original before leaving just the R G & B channels

Re: Turning RGB channels into layers

Purest way to do it is just to load the channels as selections, fill the layers with the primaries. And then fill 'Behind' on each layer with black. Blended with Screen for RGB. CMYK works with Multiply, because its an 'additive' space, with white (representing paper) as the base.

I've always thought this would be a great teaching tool to explain how the colour models work. Certainly for demonstrating ink plates in CMYK, sliding them into place with snap to edges on.
