First, here is a shot of the rill, looking east toward the morning light.
Attempting to capture both the leaves and the reflections in the water was quite difficult from the point of view of depth of field. Although the leaves and the reflections of trees would appear to be at the same distance from the camera, from the point of view of optics, the reflections are effectively as far away as the actual trees, that is to say, at a much greater distance. So even taking shots with very narrow apertures (running from f/16 to f/40), left the reflections well out of focus. And if I focused, instead, on the reflections, the leaves were badly out of focus, which was much worse from an esthetic point of view.
This first shot shows the general pattern of leaves that I had spotted. The reflections of trees were largely lost among the leaves. I underexposed this as well as the other leaf shots to darken the water, and that brought out a different pattern that I had not noted before. Some sort of surface tension process was occurring, creating a series of concentric lines around the edges of the leaves. These I enhanced a bit in post processing.
In the following shots I focused on smaller groupings of leaves which showed a bit better the surface tension effect.
Finally I got a shot that included both the surface tension effect and some recognizable (sort of) reflections from the trees. This was taken at an extremely narrow aperture of f/40. Even so, the tree reflections are very much out of focus.

Interesting! Not being a photographer I wouldn't have noticed (or thought to try to capture!) the effect of movement around the leaves. It looks as though they're trembling!
ReplyDeleteMary Anne, Although it looks like the lines represent movement, I think they are the result of surface tension and are not actually moving. Just a guess.
