I've been trying to get the William Eggleston (dye transfer print / technicolor look) in my spare time for the last few weeks and can't seem to crack it.
I found a 40 second Technicolor tutorial online (by the people who did "The Aviator) but it's a bit on the vague side... & there's one step I don't understand... at second 9 they illustrate extracting a black & white image from the separate RGB channels (they call it "red matte filter", "green matte filter" and "blue matte filter". This doesn't appear to be the same as selecting the individual RGB Channels in photoshop... it's almost as if the images are inverted (they're only showing part of the image contrast).
Can anyone shed some light on this? I'd really like to be able to achieve this look via this technique in Photoshop.
Any insight or advice would be greatly appreciated.
