you dont need it...in fact it gives you a clue to what the plugin does anyway on that page

Here we load the first image with Load RED to became a Red channel, Image 2 as a GREEN channel and image 3 as a BLUE channel and press Make.

in fact what its actually doing is taking the Red R channel from image 1, the Green G channel from image 2, the Blue B channel from image 3, copying them one by one and pasting them into their respective channels in a new document.

Look at the attachment, I made this from the 3 images they have on that page which is the same as the plugin's result. This contains the R from image 1, G from 2, B from 3.

you dont have to copy my technique the same way, you could swap the channels you pick and place around for different colours...

god, why would you want to emulate such an ugly effect? i guess it could be useful for making normal maps from photos though with a few modifications.

you know, hate to dig up an old thread,...but stupid me, i cant quite figure it out...i get lost when moving the channels from the 3 images, how is that done?

the closest i can get is copying each channel as an alpha, then changing it to a spot color..which sorta works but really sucks

i just see some neat possabilities for this doing still compositions...and my bros taking a photoshop class this year in HS, they have a weird art teacher that would freak if he just spit out some pictures with that effect

thanks in advance

EDIT: well, i still cant figure it out...however, i made a total mistake, and after some tweaking, i think its an awesome mistake:

no real 2D/3D use, just looks cool lol more onea your abstract art things..which i know isnt seen around here much..

No madskills? ;)

get you channels palette up...

open up image 1

make an new RGB document the same size.

go back to image 1...select the R channel in the palette...select all, then copy

now go to the new document...select the R channel in the palette, select all and paste.

you have to have channels selected in order to paste into them otherwise it makes a new layer.

repeat again just changing to image 2 and channel G, then image 3 and channel B

Looks like a rehash of Paul Harberli's Synthetic Lighting for Photography from 1992:

http://www.sgi.com/misc/grafica/synth/index.html

If you want to mimic it in PS:

Put a photo on a layer.
Put pure red on another layer.
Set the blend mode to multiply.
merge the 2 layers.

repeat with another photo and pure green. multiply and merge the 2 laters.

repeat with another photo and pure blue. multiply and merge the 2 layers.

You now have 3 layers. one red, one green, one blue.

merge them all with linear dodge (add) as your blend mode.

done.
