Misaligning color channels on purpose

Hi

I've noticed that quite a few fashion editorials use "misaligned color channels" (for lack of a better description) as an effect.

The attached image is not the best use of it that I've seen - but you should get the effect..

But how did they do it? Using "Split Channels" from the channels menu doesn't seem to get me there...

That's simple :-).
Just unlock your background layer by double clicking on it, go to the channels menu and choose the channel you want to move around.
Next use "Select"-"Select All" (or simply [Ctrl]+[A]) and use your move tool ([V]) to move the channel around.

Yes, as Der has pointed out. In this case the Blue channel has been moved to the right.

Am I allowed to say that I think it looks horrible? I hope it doesn't become the new "selective desaturation".

Never did it but saw it in a video about channels and masks hosted by Derek. I think the guy copied each channel in the layers pallette an set each of those layers to screen and moved each one a bit to some place. That should help. Will take a look. Mmmhhh... copying the channels doesn't work, but I'm sure he did it that way. Howevr, if you nudge th channels incrementally, you will achieve that effect.

Copying each channel into a new layer should work, if it doesn't you're probably on an adjustment layer and can avoid the non-copying by [Shift]+[Ctrl]+[C] after selecting all.
And please don't forget to set every channel to "Screen" mode and put a black layer beyond all these as some trainer on TT did.

Tried this, but the result came out much brighter than the original(?)

Shouln't be brighter. The guy Deke don't know how did this trick in a DVD tutorial called Channels and Masks, by Lynda.com. Youtube the name of the DVD, I think it's there. Probably setting in the PS Prefferences that the channels should be shown in color, and that way copying and pasting in order to get the effect. I've seen how to do that, but cannot remember the steps.

Re: Misaligning color channels on purpose

The layers should be (looking in the layer's palette)

1. Red (Screen)
2. Green (Screen)
3. Blue (Screen)
4. Black (Normal).

That shouldn't result in any brighter result, if it still does, post a screenshot of your layer's palette please :-).

Edit:
Duh, stupid me!
In order to get the layers to just affect the channels you want them to affect, double click on the layer to get into the advanced blending options and uncheck every channel you don't want to affect.

Re: Misaligning color channels on purpose

I have seen Deke do it a long time ago too, but I didn't remember, so I thought I'd give it a go. I suspect the reason for the image being too bright is that I somehow made the channels C, M, Y and lack the black channel.
