I just received another roll of Velvia 50 back from the lab, and I am beginning to notice a trend. Out of 5 or 6 rolls that I have shot since August, I have noticed that in a three shot, 1/3 stop bracket series, that I tend to the prefer the 1/3 over-exposed image. It seems to be slightly brighter, with more detail visible. How many here shoot Velvia 50 @ ISO 40? I'm not sure that I am ready to change to ISO 40, but I am thinking about it.
Oh, and that EOS-1V evaluative meter seems to be pretty accurate. Not one poorly exposed slide in the roll.
