I'm not sure what kind of maple tree we have here. In normal light, the mature leaves are a dark red-brown. The leaves seen here are new growth and are a bit lighter in color and thinner. They have a waxy surface, too, that disappears later in the season.
One discovery I made while framing this image (and of course a bunch of others I discarded) is that each bud on the tree, when it burst open, first released four leaves, followed by two additional leaves. My math is still good...that's six leaves per bud. I found that interesting. We've lived here over ten years and I've never noticed that before. Cameras help us discover, don't you think?
