Digital camera profiling is not a lot of hype. Many of us have sucessfully
profiled digital cameras. Unfortunately not all dcams work the same or have
similar software functionality which makes it difficult to get around the
unique idosyncracies with different camera designs. There are A LOT of
people who approach dcam profiling procedure in the wrong fashion. Please
seach past colorsync posts for tips on sucessful dcam profiling. I will tell
you this, the key to getting a good dcam profile is not to profile the
*environment* but rather the camera's color sensitivity.
