I like early morning and early evening, a couple of hours after sunrise and a couple of hours before sunset. However, if I only shot at those times and only when the sun was out, and the wind calm and the temp nice, I would expose about 5 sheets of film a year.
I envy those who can spend a lot of time shooting in areas where the weather is always good or at least predictable on a consistent basis. On the great plains things vary day to day and season to season. I have learned to shoot in any light ant any time of day, and how to take advantage of that condition with choice of film and development.
