Or you can do some Channel Mixing right now. Mix the blue into the red. Remember, these are fir trees of a sort that they are logging. So going to be a white pine, with perhaps a little yellowish tint to them. But it is a challenging one and a lot of fun.
Thanks for advice daygraphics

Too sharp for my liking on that one :S

I used High Pass Overlays as you say. What a high pass filter does is extract only the high frequency information of the picture. That means that everything will remain a neutral grey except for border areas where contrast is maximum.

On the other hand, smooth gradients of light and color belong to the low frequency side of the spectrum.

There's a threshold slider to decide how much do you consider high freq. So adjusting this into a new layer (in PS: Filter >> Other >> High Pass) and blending with "soft light' or whatever method you feel like is a great way of emphasizing your bordes without affecting the color. Even more, you can then blur a little evenly coloured areas on your picture layer (or a copy of it) and smooth out grainy colors without affecting your borders!!

Finally, being able to mask this effect out very easily is a great way to gain some depth (by masking with a circular gradient). Plus, it is nondestructive as it is always applied on the high pass layer, not the picture.

I used it for my entry here:

Nice info @justanartist. You can also find our 4 sawyers at Lake Onega (Vytegra) from 1909, and the rest of Prokudin-Gorskii's collection, digitalized at the online Library of Congress.

Re: Aug-Sep 2014 Merge Channels Contest

Ok... seeing some other interesting and gallant attempts at this. It gets harder the more you get into it. You start to realize that - or at least I did - that a first attempt wasn't bad, but also not so good. I am fine-tuning and narrowing in on colors I think are believable, and likely. Here is just a small-scale version of where I am heading. Also, a full size frame of the boss' head!

Re: Aug-Sep 2014 Contest Discussion

I am actually in a RESTORE mode right now. In addition to finding and settling in on your way to merge the color channels, and fine-tuning them - optimizing color, I am focusing in on the RESTORE section of the challenge. I am pretty happy with my color these days (may still do bit more), but I am really trying hard to eliminate all the scratches, color aberrations and negative fade that has occurred in the original.

Pretty cool Vincent. I like it. You know when you Save for Web - it converts your file to an sRGB format by default. You may want to Convert to Profile (sRGB) before saving to Save for Web - and that may save you on some of the visual differences you are seeing.

Talking Re: Aug-Sep 2014 Merge Channels Contest

RichieMB... nice play. Good merge. You are probably like a lot of us. Came in pretty good, but there are areas that you see can be improved. Also, like a lot of us here, finding time (between real work) to fine tune and adjust further is almost as much of a challenge, as the challenge contest itself. But "I" am hooked. I keep working it, and keep making improvements (IMHO) to my first show. Going to reveal my high res link at contest deadline. Just a couple of snapshots of my newest, most recent status...
