Source> your image
Then tweak the sliders
Trying to sum it all up
Here I am, on a relatively quiet Sunday morning, trying to understand.
Several of you just - which were Stroker's words? - tweaked and messed with Curves and Hue/Sat, and by magic, a decent image appears. Too difficult for me. I get the impression I really have a colour sight problem. After an hour or less, it is all one big mess and I get the feeling I cannot distinguish red from blue anymore.
[A side note: My keyboard (electronic musical instrument) has the possibility for tuning. I can easily hear the difference between 440.3Hz and 440.0Hz. Now that's a difference quite a bit less than 1/1000. Not so with my eyes ]
So as opposed to the tweakers and messers, whose level I will never reach I try to understand the ones of you who have done really strange things.
"The blue channel was the one with the problem"
What problem? How to adjust? (Duv says he raised Blue)
"Extract Hue to colour..." "Extract saturation to Red..." "Extract luminosity..."
Real dumb question here: What do you mean by that?
Did you do a manual Auto Levels really? Like byRo in the next post?
I duplicated your method and got the same result, so I passed test #1
How did you notice that the colour problem was different between highlight and shadow? This is something that would be very useful to learn.
I liked the trick of "reusing" the Channel mixer with Luminosity blend. Cool. And thanks for reminding about the reduced Opacity setting. I use it a lot, but tend to forget (for some unfathomable reason!) that I can use it all the time for any layer.
I think calibration is very easy??? Just check "Advanced", which isn't advanced at all.
In desperation this morning I tried CMYK too. Dead end for me. But I "stole" your eyes desat trick
venivedi (almost vici )
Just a comment: "daily work"? Home at 01:22? I don't call that "daily"
Comparing the various attempts here; I see that the ones I like best, all have in common that some attempt has been made to take care of the blown Red channel, either as a direct frontal attack, or more indirectly. That includes venividi, byRo, nkollias and myself. In all the other images, there is a washed-out quality (quality???) to the image, although the colours may be superior to mine. I think from this I can deduce that no channel should be allowed to be blown, ever. At least in facial shots.
Also there is the trick to copy the L channel from Lab. I have done that in the past, but forgotten about it One should probably retouche a bit every day, if it hadn't been for my daytime job. Time to retire...
7500K is too high I think. Depending on whom you ask, daylight is somewhere between 5600K and 6500K. I don't know why the other choices are available at all.
Rest of the gang
You didn't do anything I didn't already know, except you did it better than I
Unfortunately, that doesn't help me much! Practice practice practice
BTW, are you all aware that you can use the arrow keys in Curves to adjust the point? Sure beats the mouse.
Made a hue/saturation adj layer .set master saturation at-23and hueat-2,red saturation at-5, and yellow at-5. then I made a levels adj layer and because I couldn’t see anything in the picture that I thought should be white I used the black eye dropper on her pupils to set the black point. Then on the red channel I mover the black input levels slider to 21. Then duplicated the background layer twice and on the first copy adjusted the saturation to extreme red applied a layer makes and painted back in the lips with a 60% brush and then adjusted the layer opacity until I got the “right” look. Same process for the second layer only used green for the eyes

The hues have been "extracted" to colour.
Saturation has been "extracted". One side is greyscale and the other is just in the R channel. Pros and cons to both ways.
This is Photoshop's flavor of Saturation.
This is Photoshop's flavor of Luminosity.
*See link to other thread for my PC/Win plugs for help with this. If not PC/Win, I can show stock tool ways of doing all of that.
Tear apart, fix the individual pieces, then put back together.
Since Sat and Lum are Photoshop's flavors, can be put back together right in the Layers palette with Blending modes and can be tweaked with your favorite adjustment layers.
This past week or so, I've been doing some very interesting stuff.
I understand colour cast much better and have come up with some very promising plans of attack.
I get all goose pimply thinking about it.
Hello, Rexx. I'm back home 10 minutes early than usual.
denschneider, I like your work because she looks warm and friendly.
Interesting stuff you've attached, Stroker. Thanks for sharing.
