I like LAB - used it tonight to correct an order for one of our pros. Will make a post in my blog about it soon.
And where is this blog?
Where do we stand with the synopses of the remaining chapters?
I just got the book for Christmas. So far I'm loving it, especially the second half of each chapter. I recently finished the Total Training for Photoshop CS (about 25 hours of video)l
Goodness you sat through 25 hours of video. Please enlighten us on the fun things you've learned.
I've used photoshop a bit in the past but never learned advanced things, I always used basic stuff. So there were some things that I knew in the training, but what was interesting was I was constantly learning new tricks and tips. Sometimes I fast forwarded through boring parts but overall I think the Total Training program is excellent. Overall I learned a lot of theory and practical uses, like the channels which I had never used before and the blend modes. I find now that learning new techniques is much easier now that I have a good foundation! For example I'm picking up l*a*b really quickly, and am getting good at extractions using channels (in lab mode).
I'm curious, how many of you use lab as your primary colorspace? I mean you save your 'master' PSD file in lab and only convert to RGB to save as JPEG? I use a lot of adjustment layers and switching back and forth between lab & jpeg isn't possible, so I'm curious how people handle this. It sounds better to just stay in lab.
I finally have my copy of Dan Margulis' new book, Photoshop LAB Color : The Canyon Conundrum and Other Adventures in the Most Powerful Colorspace. This book is a runaway bestseller and I know that at least some dgrinners have it.
What about organizing a reading group to help us all get through it? We can rea a chapter a week (or two weeks?) and share questions applications of the ideas to our own shots, &etc. I think we are more likely as a group to get through it with good understanding than as indivituals.
Who is up for this? Anyone?
At Rutt's request, I'll write up Chapter 14 in the next few weeks.
I have some really stupid questions, where can I ask them anonymously. Things I didn't understand in the first place and don't understand now.
For instance: the numbers...............I have no idea how anyone sees this zero number thing.
At the bottom left??? I have learned to use those numbers in my own way, but I am fudging. I have a lot of stupid things like that that I don't know.
I noticed on Rutt's explanation on my challenge thread, I thought, "uh, I don't want Rutt ever to know this, and I am sure I did something close to what he is talking about, but I have no idea "what he is talking about".
That kind of thing. Where can one be stupid and not be told to do homework and stuff. I remember David, way back at the beginning asking about why his numbers didn't match Rutt's, and I did not understand the answer, so "search" would not be an option now, I still would not understand.
I, uh, did my dog photos, which I am sure you all rushed to see here
were done almost entirely in LAB (blk and white started in LAB), without this stuff that I don't understand at all.
So, I can get by, fast and dirty, knowing little, but I feel a bit stupid.
I found this forum, yesterday...
Hmm... I have not had any problem understanding the LAB book. But know am I at chapter #14 and its a bit hard to understand. I hope that the dgrin Lab-topic will add the 14th topic soon.
Hmm... If I have a picture, let say of a landscape with a blue sky, and the sky is a bit dull and need to be bluer. WHY use the Red channel? Maybe Im a bit lost in RGB color space. But the compliment color for Red is not Blue - right? Well, im sure I understand if I read the chapter again and again.
Timely question. I'm working on the chapter 14 writeup for posting on dgrin now.
Great, and thank you. I must say this is the best way to read a book on! If someone is not understanding something - just post the question in a forum and you will get an answer within an hour, mostly.
I hope it will be more book topics like this one. Maybe when Dan's Professional book arrives. ;-) Must say, I realy love LAB. Only thing I miss in it is the neautral pipet in the curves/levels. But its in ACR anyway.

The red channel is good for contrast for blue skys with white clouds because the blue sky has very little red and the white clouds need a lot of it in order to be bright white. The blue sky often is a bit cyan and so may have a little green. But it cyan is the opponent of red, so you won't find any red there. Only at sunset, sunrise, in rainbows, &etc.
Green is good for contrast in faces because faces are basically red. Sometimes the blue channel has stuff you want, but usually you can just take the green for a good B&W of a face. Why green and not blue? Maybe someone else knows.
