I live in Durango, Colorado, paradise, where the skies are blue most of the year. We experience lots of sunny days out here, “Bluebird”days. The cerulean blue sky is great for aspen photography, especially with the golden aspen leaves against the sky. But my tastes run more towards the big scenic landscapes. When I moved here in 1995 the sky was the reason I stayed. The feeling of expansiveness is everywhere and expands my life, my heart and my photography too. When a storm rolls in, especially during our monsoon season in the summer, I often head up into the mountains to photography scenes with great skies. Even when photographing wildflowers, I try to include a cloudy sky for drama at the top of the scene. A graduated neutral density filter comes in handy to hold back the detail in the brightest highlights in the clouds.
Try this exercise, set up a landscape scene with sky, middle ground and foreground. Pay attention to your composition, check to see that you have done your best to NOT make the scene 50% sky and 50% land. Go back to this scene often and photograph it under lots of different weather conditions. When I photograph grand landscape as well as most other subjects I use the AV mode so I control depth of field. When the closest subject is closer than 10 feet that’s the time to use really small apertures like 22-25-29-32. Otherwise a sweet spot on your lens is probably closer to f16.
