Default Colors by the numbers and more ...

Hello my friend!

You're welcome - however I'd say the benefit of learning is on my part. :)

My screenshots are there now too.

About my workshop:
I spent some time investigating the original jpeg - by numbers, eyes and even brain mind you ;).
I poked around with rgb, cmyk and lab (every picture has 10 channels, right ?) and some combinations of them to get a feeling for the feasible.

About your comments:
1. "major color cast": Doesn't it have a major one ?? Try to reproduce the changes in screenshot 1 - I think it has.

2. "workshop intent": I surely confused my intent with yours :)
But don't mistake it - as soon as it is published it's out of your control and since you allowed workshop posts ... here we go.

3. "mistakes": I measured the points as follows:
1: a=-2 b=1, r=249 g=252 b=249 (cap: slight green)
2: a=13 b=13, r=96 g=64 b=52 (right hand: red)
3: a=11 b=15, r=130 g=99 b=81 (left hand: yellowish red)
4: a=17 b=9, r=114 g=75 b=73 (right thumb: red)

You can count the shadows as the price of the different moves all the more that imho they don't really contain significant subject related infos. Concerning the background the only usefull info there seems to be some colors (the white of the shirt, etc.).

So yes it is based on "by the numbers" and is more than that... (ouch this is toward self-praise now).

Thank you for the good learn so far.
I keep on rtfm-ing :))

See you soon.
Atti
