Latte' at the corner espresso bar...
day dreaming....

admin stuff I understand....lol Kidding...

BTW I want to learn more about this LAB L channel copy process. I tried it last night and I think I only have about half the story. I seem to be missing the point...

Sigh...

Greg,

Here is an action which you start from an rgb image.  It create a duplicate image and set up the layers for you in Lab mode. 

The action is called ColourByTones and uses FlatCurve - ignore the rest of the stuff

The action only does the L channel duplicate at the moment, but remember you can use any channel as the seed, and to blow your mind you can select different 'masks' to seed each of the 3 lab channels - that's why I've split up the action, to experiment.

Have fun and tell us what you think

I shall give this a test fly...

I knew you'd distill this down to an action....I kind of thought it was a lot of steps for anyone to try to remember it all.

If you could then tell me how to use CM instead of PS's curves - that would be great, but I can not work out how it could be done.

[Greg Groess]

could you eliminate the curves layer since you are going to do curves on the layer below it??

Seems to me the need for the curve layer is a PS problem....
take a run at it..I'm going to as well

Greg, did you ever try the action I put up here: http://www.hcs.harvard.edu/~jrus/colortheory/Jacob's-Ladder.atn

[Greg Groess]

I am still struggling with this.  I have to go back and re-read the original posting...I just seem to be messing the image up worse that it was...

I can see the subtle adjust ability here and I want to understand more about this.  I'm going to read up again....
Thanks for the nudge...

Time to go to school

Here is my stab at it, the first one I adjusted in RGB and the second in LAB. If anyone is still checking this thread, let me know what you think.

OOPS, I didn't add the images...

Oh I'm checking...
I'll have more to say later on...

Brookrouge,

Take your first image back into CM in Lab and try to boost the color a bit...
See what happens to it...It looks pretty good so far..there is more in there as you have seen.

Just found this nice picture. Tried to apply my standard workflow. First corrections in Lightroom, setting neutral, inceasing exposure, contrast, saturation, clarity and some sharpen. Exported to PSE and made some final adjustments in PSE/CM first adjusting colours and neutral in RGB. Then to Lab mode and  fine adjusted BW and increased saturation. Very fast worflow but do not like that I sharpen before going to PSE/CM.

PS There is a blue haze in the background which I tried to limit with a mask and decease blue. DS

I was able to remove the blue hue without using a mask, I'll keep working on it when I have time. Thanks for the feedback.
