Thanks Rowland and KD! I appreciate the kind comments!
Rowland - I am using Unity as my gain setting....139 i believe is the actual number. I found that this gave me results i am happy with. I find that 300s brings out enough detail in what i'm shooting without blowing out the highlights (for 90% of objects anyway). If i were to image something a little fainter i may change up the settings but i'm happy with my results at Unity Gain.
I havn't dipped my toes into LRGB imaging yet but i would assume, like you, i would keep my camera settings the same for an easier a calibration library!
