what do you think they do?
hint.
look at the channels as you change the check boxes.
I don’t need sarcasm here, please–I can certainly see that my image disappears from each color channel as I click it–but that doesn’t really answer my question.
Catherine, honestly, he’s not being sarcastic at all. He’s asking you to try to figure it out by looking… on the assumption that you can and will figure it out. In my case, he’s been right far more often than not… his questions make me look harder.
I should also add that I NEVER noticed these options in the dialog until you mentioned them here!
Hey Mike! What do they do?
like I know?
hmm..
and yes, Doug is right, it’s not meant to be sarcastic.
Think of it as a way to channel mask.
think!
play with the damn thing.
you tell me what it does.
I don’t think the question is "what," but "why"?
I would have never discovered this little hidden "goodie" either except for this thread, but for the life of me I am not seeing any reasons why I would ever use this option. I guess I will just have to "play with the damn thing" a bit more…
Okay–I do have an idea now–since it seems to actually "hide" the checked channel of the layer that is residing in the Layer Set, might it be used as a type of masking option? Hey Chris Cox–where are you when we need you?–and why is there NO information anywhere at all in the Photoshop documentation????
I use it to create editable color tinting effects.
I use it for key lining and object in the black channel.
I use it for complex illustrations whereas the need for "advanced blending" is required and I don’t need to use a layer mask.
It’s a production tool as well as an art tool.
It’s up to you to figure out what to do with it.
They are for controlling channel specific blending (blend only R, blend R and B, etc.)
This should be in the manual.
(Catherine – you know, I _do_ have to sleep sometime!)
