hi,
can you explain color mapping-Intensity exponential?
When can I use it?..interiors…exteriors?
thanx
Fabrizio
Well, you can use Exponential color mapping when you generally want a more warm atmosphere in your image. But again, it depends on other settings also. 
thanx
Well, the “Intensity exponential” mode is very similar to HSV exponential in that it preserves the ratio between the red/green/blue components of colors; the difference is that it doesn’t do the RGB → HSV → RGB conversion (which may lose some precision) but produces the result directly.
Best regards,
