Hi Guillermo, Thank you for your reply. Obviously, I miscalculated the math for my exposures (*sigh*). However, just to clarify..on the calculations given below, wouldn't it be f16 @ 1/100 secs and not 1/25 sec? I apologize if I am incorrect, but I'm trying to understand the basis for the

Bill, Here is a brief analysis I've done: Assuming bright open sky conditions, shooting snowy scenes call for about +2 stops from whatever the meter indicates for the snow. Using sunny/16, your exposure should be f/16 @ 1/25 secs. There are about 10 stops separating f/16 from f/500,
