I have been fooling with this for a few years. I didn't want the compositions to be exactly the same or to shoot from the exact same spot. I wanted each image to work on its own as well as in the set.
I took the fall color shot last week.
Now I can go shoot somewhere else!
FWIW 3 of them were shot with my Canon 5D and the summer sunrise was shot with the Olympus 420 and kit lens.
