When photographing trees, my eye is caught from a distance, by some interesting feature. Maybe the tree is an outstanding specimen in its own right, maybe it is struggling against the landscape. Sometimes it's one of many and there is nothing especially unique, except the way a certain branch hangs down. After seeing a tree I want to photograph, I will walk right up to it if terrain allows, otherwise I will walk around so I can see if the thing that caught my attention looks better from a different view. Once I have selected the direction, then I look at the surrounding trees and landscape for contrasts or repetitions. I'll back away while looking in the finder until it looks better or worse and then correct. Then I'll work on the composition of the photograph. What's your approach?
