Hi Rico, I've been shooting with the X-Pro1 (and a variety of x mount lenses - prime and zoom) since it first came out. I'm a documentary photographer and most of my work is shot with the intention to convert to b/w, although I do color work also. I shoot everything RAW simply because I think - maybe mistakenly? - that it's better to work with as much data as possible when bending and twisting pixels. I am confused about what DR actually means for me. I have mine set to 100 and have never thought to change it (I shoot shutter and aperture manually and auto ISO ). So I guess my questions are: 1) Am I missing out on something by not adjusting the DR? 2) What will adjusting the DR do for me given that I shoot RAW and manual? Thanks.
