There are a very few days in spring, when the trees are just beginning to leaf out, that the forest has a texture mixed between the hard branches of winter and the thick obscure leafs of summer. This texture reminds me somewhat of a Jackson Pollack painting.
This page has a number of crops made from one successful image made on Easter holiday weekend. Over a hundred pictures were captured, but we've learned from this attempt and we have some ideas on how to be more succcessful if the weather (and the speed of leaf growth) permit us to try again next weekend.
Actually this forest has a good mix of tree species, not just alder. It also has birch, beech, maple, cottonwood and many others.
