I just want to really thank whom ever recommended the "Real World Camera Raw with Adobe Photoshop CS".

I've been shooting DSLR for about a year and a half now and I thought I knew RAW. What I didn't realize is the difference of how digital cameras capture light compared to how we see it and even how negative film sees light. I've always have the approach of under exposing if anything if I'm not sure. I learned that isn't such a good idea as it was with shooting negative film. According to this book, half of the information captured is in the lightest stop...half, that's amazing (and bad at the same time, lol). And that you can actually recover what you think might be clipped (dependent on camera model). I did some testing and I found that I could actually recover some 255,255,255 clipped parts of the photo and make out some detail as long as it wasn't too bad. It's works best when at least one of the channels isn't clipped but there still seems to be a little bit of head room if it isn't.

This is all possible because you can actually tweak these values BEFORE the conversion to RGB Gamma like as if you shot JPEG and not RAW. This book also gets allot into automating your workflow for those not too sure about the over head of shooting RAW.

quick sample:

[IMAGE TOO SMALL, NOT RENDERED INLINE]

Anyway, thanks again for a pointer to a great book about camera raw.
