tekmaster Registered: May '03	Date Posted: 3/8/05 5:54pm Subject: 3 Strip Technicolor, cooler than a Jimmy Dean in a freezer
	Ok, I was checkin out the technicolor demo techniques shown on www.aviatorvfx.com. For all of you that don't know, that's the visual effects site breifly going over technique used in the Winter blockbuster, The Aviator. ANYWHO, I was wondering if any of yalls would know how to acheive the effect in Photoshop? I know the math behind it, I just can't for the life of me figure out how to use the math and acheive product in photoshop. Here is the equations for the color channels in order to a acheive a 3 strip technicolor look: Red: Red - ((Green + Blue) / 2) Green: Green - ((Red + Blue) / 2) Blue: Blue - ((Red + Green) / 2) -----signature----- Things That Suck: 1.

	The Aviator wasn't even close to a blockbuster. That Aviator site is neat though. And Figger, go to that site he "linked" to. The one I just said was neat. -----signature----- The Mighty Blueonic One of the Neverending and Excruciatingly Painful Padawanship A-H-B-Y ~~! !~~ it is the duty of a patriot to defend his country from its goverment

	Red: Stop trying to be funny. Not working again. Anyway, hey, they did it in AE at first. Neat. I'm unsure of how to do this with the math provided, but the pictures of the process speak volumes--I've got a method on the tip of my tongue (..fingers? Brain?), but I'm not able to articulate it just yet. -----signature----- I'm so adjective, I verb nouns. RIP George Carlin!

	I think I got it. I'm using Photoshop for the proof of concept, because I don't have AE on this computer. It was done splitting the channels into three JPG's, but if you can't do that automatically in AE, there'd be ways to fake it. So start with that, take your clip and get the red, green, and blue channels on different layers. Now, for each respective layer, the red channel, the green and the blue, up the shadows in color balance for that color, and down the highlights for the two complementing colors. You should have one where everything that is red, is dark red, and the rest is light red. One where everything that is green, is dark green, and the rest is light green. Andone where everything that is blue, is dark blue, and everything else is light blue. Set the two top layers to lighten. Bam. Now, for added punch, make a new comp, put the first comp in it, and up the saturation a little. -----signature----- Defunct.

	Just tried my method with those three B&W stills on the site, the tiny ones in the bottom row middle picture. I got an accurately colored image out of three pictures with no pre-existing color information, so I know I'm on the right track. -----signature----- Defunct.

	The right way to do the math in Photoshop is to use the Calculations command under the Image menu. This will let you add, subtract, and average the channels. I'm not certain that your calculations are correct, though. I got better results with: R = 2R - (G+B)/2 G = 2G - (R+B)/2 B = 2B - (R+G)/2 This is your calculation with the original image added (linear dodged) onto it. Here is my original: And here is the Technicolor version I produced: For some reason, though, when I did this to the example from the Aviator web site, I got a brighter image than they did. Perhaps it's a gamma issue in their web images. But in any case, use the Calculations command, combined with Linear Dodge (to add RGB values) to implement your equations.

	How exactly do you do that in the calculations window? -----signature----- "We Will Spread Rational Inquiry By The Sword!" I may be wrong but I am NEVER in doubt.

	Oh yeah, I remember what you're talking about. That was a cool scene, visually, and I was a little curious. BTW: "Winter" and "blockbuster" usually don't fit together well. =) -----signature----- Fanfilmers shoot first and talk copyright later. http://www.vimeo.com/vaportrail/videos http://thespenceleyspoileriffic.blogspot.com/

	Still trying to figure out how to do that in calculations... -----signature----- "We Will Spread Rational Inquiry By The Sword!" I may be wrong but I am NEVER in doubt.

	To compute (G+B)/2, select the Green channel in "Source 1" and select the Blue channel in "Source 2". In the Blending pulldown, select Add. Set the offset to 0 and the Scale to 2. Select "New Channel" in Result. This tells Photoshop to add the blue channel of Source 2 to the green channel of Source 1, then scale the result by 2 (i.e. divide the result of G+B by 2) and put the result in a new channel. Rename the new channel to something meaningful (I called mine "(G+B)/2". Now to compute R-(G+B)/2, set the Blending pulldown to "Subtract" and put the Red channel in Source 2 and the "(G+B)/2" channel in Source 1. Set the Scale value to 1 (since we don't want to divide the result this time). Now you'll have a new channel that has R-(G+B)/2 as its value. I went through the same process to compute channels for G-(R+B)/2 and B-(R+G)/2. Then I split the channels and merged the three channels I created into a new image. This image obviously wasn't a Technicolor version of the original image; it looked a lot like a matte that needed to be added to the original image. So I pasted the original image over it and set the blending mode to "Linear Dodge" to add the RGB values of the original image to the RGB values of my image. This resulted in the Technicolor version I posted above. For more details about doing calculations, see the section "About the Add and Subtract blending modes" in the Photoshop help.
