Ed and Murray. Thanks a bunch for your comments. It makes me think I actually know what I am talking about. I am still very new in LAB although I have got this book which probably puts me ahead of a number of people in regards to understanding it and knowing what it is capable of. I am by no means very good at curves myself but knew them alright and am learning them fairly quickly since I really don't have any other choice with this colorspace. In response to writing up a tut on LAB, I wouldn't know the first thing to write about and, as I previously said, my understanding of it is lacking to the extent that I don't know if anything that I could write about would be of value. The reason I wished I would see more lab is because I needed as much help as anyone else. It is quite a deep subject. Simply seeing other people's questions and how they are answered by others is helpful as I'm sure you know.
With that having been said, I wouldn't mind and would even enjoy writing a tut if any of you thought that there was something that was both fairly basic and worthwhile for the people here. Writing a tut would help me as much or more than it would help the person who read the topic for the first time without any real knowledge of LAB. Personally, I think it would be great fun. It would force me to master a certain area of LAB to the extent that I could write a tut and that would only help me. Basically, I can write about anything in the first 5-7 chapters of Margulis' book but probably couldn't go much farther, at least at this point. That's just now though. It will improve quickly I think because I am nose deep in this thing.
The bottom line is that if you guys have an idea about something you think would be worthwhile as a tut then let me know and I'll give it a run. The first thing that comes to my mind is fixing colorcast without screwing the rest of the image in the color of the cast but as you can tell, I think there is a never ending list of things that makes it more valuable than the other colorcasts and are fairly easy to grasp.
