Crazy Homeless Guy Posted February 11, 2011 Share Posted February 11, 2011 (edited) Has anyone here ever work in Lab color space in Photoshop? If so, ...how did you feel about it? ...what were the advantages you found? http://en.wikipedia.org/wiki/Lab_color_space Edited February 11, 2011 by Crazy Homeless Guy Link to comment Share on other sites More sharing options...
Administrators Jeff Mottle Posted February 11, 2011 Administrators Share Posted February 11, 2011 Here's a great book: http://www.amazon.com/Photoshop-LAB-Color-Adventures-Colorspace/dp/0321356780 LAB color space is not a very intuitive color space, but you can do some cool stuff in there if you know what you're doing.

Crazy Homeless Guy Posted February 11, 2011 Author Share Posted February 11, 2011 (edited) That book has some great reviews. I fall into the category of only vaguely knowing what Lab is, but never actually tried to use it on anything. Then I watched this video.. http://vimeo.com/6015498 Which helped, though I am sure there is a lot more. I am starting to venture deeper into more specific adjustment curves, but find it difficult to get the subtle changes I want with a complex RGB curve (~5.) After that the slightest wrong movement seems like it throws the whole thing off. I think I am trying to ask it to do to much. I am still a bit timid about adjusting the individual RGB channels. From what I can tell, learning to do curve color toning in Lab color space may be easier than mastering separate curve adjustments for the RGB channels. In Lab I would be able to do the lightness and color separately, therefor giving me more control of the subtly of color detail. It looks as though it will also be greatly beneficial in controlling blow out when doing curves for tone and contrast.

Administrators Jeff Mottle Posted February 11, 2011 Administrators Share Posted February 11, 2011 If you want to master curves, you should seriously check out the Photoshop Advanced class that we recorded a few weeks ago in Boston at Neoscape (Lon Grohs - Instructor). I sat through all 18 hours and he is a curves guru. The recordings will be online for sale in a few weeks. Sorry shameless plug, but he's got mad skillz.

cupsster Posted February 11, 2011 Share Posted February 11, 2011 I know one person which is doing postwork with LAB and my eyeballs were spinning when I saw that.. LAB is worth to check and gold to master.. It's on my long-term skills TO-KNOW list Link to comment Share on other sites More sharing options...
Craig Ramsay Posted February 11, 2011 Share Posted February 11, 2011 I switch my images to lab when I'm doing sharpening so that I can sharpen just the brightness channel, but that about it. Link to comment Share on other sites More sharing options...
mattclinch Posted February 11, 2011 Share Posted February 11, 2011 was aware of it, but only just tried it out. brilliant for colour correction. Link to comment Share on other sites More sharing options...
Stephen Thomas Posted February 12, 2011 Share Posted February 12, 2011 I've just dabbled in it myself. Using levels or contrast adjustment on the 'a' and 'b' channels to make colours pop without introducing noise like an RGB saturation boost would do.

My immediate curiosity goes to the balance of focus in regards to 'rendering color correction' vs' photography color correction?' I have had the pleasure to hear Lon speak before, and he posses a good deal of interest in both ends.
