II = aRGB color space and best used if your going to PP the shot.
The color space is considerably larger so colors are more
faithfully retained...but looks horrable for web sharing.....so
always remember to convert to sRGB before posting on the web or it
will look VERY flat and lifeless....but the value of colors
retained is worth the conversion step (which takes only a few
seconds)
III = Boosted reds and greens usually for landscape work you dont
(again) plan much editing in. Skin tones will usually look horrable.
I shoot mostly landscape work so I shoot RAW+jpg in Mode III so my
small .jpg files will come out showing what I want....but my RAW
converter converts to ProPhotoRGB (an even larger color space so my
colors stay intact till I convert my finished product to sRGB for
web sharing...or whatever the lab needs for printing).
Color space managment seems like voodo till you get what is happening.
If you have any other questions....ask away.
