Re: Amazing skin, only degrunge?

How do your color moves relate to print?
What workflow do you use to ensure colors and contrast
are within bounds/gamut. (talk about profiles, using RIPs,
UCR/GCR, calibration across devices, the whole can of
worms..)



I'm sure more questions will arise but that should get things
started no? [/QUOTE]

Hi Captain:

Sorry for my ignorance but, can you tell to me de meaning of UCR/GCR?

Thanks a lot.

UCR: undercolor removal
GCR: gray component replacement

Re: Retouching topics of interest

Thank the stars, a thread about something other that skin! In some situations the best (or as good as best) way to achieve certain massive shifts in color is in fact with Channel Mixer. Knowing where you are headed comes with knowing a bit about color theory, so its a dark art, but there comes a point where everyone needs the channel mixer.

Re: Retouching topics of interest

Guys, just wanted to say i'm really glad to read your posts again. I have to say I got tired of these "Demystification of Mr or Mrs..." and it was months and months before something constructive were posted.
Thanks for coming back!

I know it's a giant can of worms, but can you elaborate on how you
use the channel mixer this way?
What do you consider a massive shift in color?
Are you talking about basically re-coloring?

Can you give an example of a situation where you will use color theory
to dictate where you're headed, and how you get there?
I know that ain't easy, but i'm sure people will appreciate anymore
you can add.

Re: Retouching topics of interest

JavierT ~ I appreciate the kind words, but i was kinda having fun playing 'interviewer'
so would rather keep firing out questions if that's okay.

Me harping on about some curves/gradient maps/etc prob won't lend much to the
discussion at this stage.

It would also be very easy to point out things i did that would be better
achieved with other methods. I was quite lazy with the D&B too. :P

To satisfy your curiousity though, i have put up the psd file for you to download.
I may have been lazy and not named layers so if so, i apologize but you should
be able to 'deconstruct' what i did from that.

PSD for Javier Pic

Agree completely. Massive moves, or severe repair work on a damaged plate. But if a standard move is called for (say, increase magenta in the mid-tones) the Channel Mixer is so wrong in so many ways... Unfortunately, I still see it used this way by people who are supposed to be professionals.
