Export separate video channels R, G, B, etc

I’m glad you found something that works for you. I’m surprised that 126 does what you want as it’s sort of a random number 🙂 Also I wouldn’t expect that to turn any channels ‘off’

I’d be curious to hear more about the process you’re using.

Fat-fingered… actually 128, half of 256. I found it was needed to eliminate any luminance component.

the Background: Several years ago, I attended a seminar by Dan Margulis where he taught a process he called picture postcard workflow, centered around using Photoshop to greatly improve any still photo. Dan is one of the few pre-press experts, wrote the Professional Photoshop series of books and also a weighty tome on Lab color, considered by many to be the definitive work on Lab. Since that time, I’ve attended Dan’s other seminars and worked my way through his training series on the NAPP website.

One of the techniques he developed uses blending of channels from other color spaces to improve photo contrast and color. Using that technique, I was able to work minor miracles on a still-frame from footage provided for a current job. I could script the process to work through a frame at a time in Photoshop, but there is a lot of footage. So, right now I have been experimenting with ways to extend the tools to use with video. If I have any significant breakthroughs, I’ll provide updates here on the COW.

Interesting. Well if you’d like any help finding alternate methods to achieve a similar result feel free to post back. I’d like to see the miraculous still frame before/after 🙂
