Sorry, I thought since I wasn't claiming it to be mine and it is watermarked, it may be ok. I have replaced it with the link.
Cool!
I figured it had to do with toning for specific colors but anytime I do that, it just changes those color channels themselves (e.g. red shirt gets lighter or darker in the conversion etc.). This seems as though multiple layers are added over the standard converted image to add some yellow and possibly green tint. It is very cool and I love whenever I see a conversion like this. Just have no clue how it's done.
When people shot with Black and White film they typically used filters to "tweak" the color channels.
With digital, if you shoot Raw, you are free to tweak the color channels to taste. If you set your camera to shoot B&W jpegs, well, you want to tweak the channels in the camera.
Either way, I'd say it can be a long process of trying, failing, trying, get some success, learning from it all, and trying some more!!
