02 Sep 11. With my graduate work in Biomedical Science /Engineering centering around vascular physiology, and in particular the flow of blood to the brain under high g (accelerative) profiles, I found that my interest on how certain plants move fluids around began to really concentrate on how trees do it, especially very tall ones. While I've never found a formal answer, I have some ideas as to how it might be accomplished. The engineering design allowing for such a feat has to evoke definite appreciation for the intelligence behind it. Of course, there is more than just one way in which a plant acquires the water it needs, and sometimes, if you have a critical eye, you can easily spot at least one of them. The "summer" rains about which I've complained a time or two this year offered opportunity for me to capture a least one obvious way, but one that is probably overlooked because it requires that you be either out in the rain or outside shortly thereafter. This shot was taken in between "rain showers" of the type that might remind you of standing under a shower running full bore, and which were prone to smash the plants flat which they did on more than one occasion. The light level was very low, the wind was blowing, and it was one of those shots you attempt to get of a moving subject with reasonable detail. To get sufficient speed for a marginally sharp image it was a compromise all the way with shutter speed, aperture, and ISO. The other option was flash but the results I was getting with flash tended to destroy the "focus" of the image. ISO 400; 1/160 sec @ f / 8.
