Precisely.

I understand that and the channel mixer makes all of this easier. Yet, if I want to blend other channels (L* etc..) the antiquated method will still do it.

On a seperate note; the method explanation I originally postes sounds misleading:

"he blended 25% of the cyan channel into the magenta channel. Interestingly enough, he used the magenta channel to mask itself out by checking Mask and Invert."

In fact, the result is 25% of the cyan channel into the magenta, yellow and black channel (he blends into the cmyk composite).

How one would achieve that with the channel mixer?

Thanks

That's trivial with channel mixer. Just set them appropriately. Whatever you do, it has to be equivalent to some sequence of mixing operations, and you can work through it in a minute or two.

The thing about blending the L channel is the worst idea anyone has ever posted on here, because it doesn't follow a scale similar to any other channel, so it makes no (mathematical) sense to take a linear combination of it and something else.

Blah blah blah blah blah. Pursue these geeky nits if you must.

I'm. Not. Interested.

Exactly. Doing actual work is far more entertaining. What is the point of experimenting with something that can't possibly be of any use?

Re: Interchannel Color Correction

I think he would be happier with an actual image processing toolkit rather than photoshop. That would allow him to specify adjustments in a much more principled manner, and they do in fact support the same color spaces. It still doesn't help if the adjustment isn't sensible.
