I just finished reading
"Real World Adobe Camera Raw With Photoshop CS3" and even though I work in Raw about 8+ hours a day, and I had read the last book (with CS2) about a hundred times, I did come away with some new things learned which will certainly help me get even more out of RAW!
Question: according to the book you should check under the Camera Calibration tile to see if your camera has a newer profile. I checked a file shot by my Canon 1DS Mark II and there were two options. 2.4 and 4.4. Mine was by default 2.4. So I changed it to 4.4. So, if I am understanding the book right, this is an improved profile for this camera?
