[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]Thanks, Bob. I don't know exactly how the M8 and my Oly 4/3 compare with respect to exposure compensation, but, after reading comments from other M8 users about using -2/3, I set that same adjustment on my E-510 and it works out pretty close. I make final adjustments in the RAW converter. Jim Nichols Tullahoma, TN USA ----- Original Message ----- From: "Robert D.
