Got to talking with the flist and we're all 'Buh? DX' over the Channel Mixer. I use it a little tiny bit. By which I mean 'for every black and white but nothing else because if I try to use it for anything else my eyes go like this O_@ and I back away slowly'. Anyway.
Micro-tutorial! Total prep time? Honest to god 20 minutes. I USED A PICTURE I JUST HAPPENED TO HAVE UP. It's late, I'm going goofy.
Step one;
all the coloring. Start with a colored image, for reals.
Step two;
Go to Channels (Window > Channels). You'll need to have a non-adjustment layer selected for this to work for some weird-ass reason.
see how 'Layer 2' is selected? Yeah, like that.
Step three
Click the different channels to see what they look like. Typically (for me, at least) Red will be super washed-out, blue will be grainy and mega dark, and green will be very close to perfect. Didn't work out like that with this one but it's an odd image, as you can see.
And this is where I've tricked you like one of those evil-ass tutorials I had to do for those freaking Microsoft software classes I took. It's not exactly nessesary to do this but it's nice to see what you've got to work with.
Step four;
Click the RGB channel. Personally? Haven't figured out how to do anything with one of the other channels selected (you can use Printscreen though. That's something).
Anyway. Open the Channel Mixer (you know where to find it). I tried to get a cap of it but photoshop's being a bitch. Moving on...
Here's the Channel Mixer. All up and stuff.
Change the Output channel to the color that you liked best. For this I'm going to go with red. Now click the monochrome checkbox.
Everything goes black.
Well. Grey. S'okay.
Play around with the sliders until you get something fun.
I didn't deviate too much with this one but sometimes I end up all over the place. Experimentation is key. I've had images where it didn't look like any of the channels were going to work and the solution was some freak combination of the four.
It's a thirty minute tutorial. What do you want from me?
Ya know I'm kiddin' right? :3
Something didn't make sense? Ask me to clarify :)
