Weight of Water

Back from my quick trip to Yosemite with the kids, Phyllis reminded me that I don’t need to go anywhere to take pictures. Sometimes one’s own backyard is more magical than any destination. Thanks, Phyllis!

This photo shows a translucent Dahlia petal with water drops resting on the petal and refecting a peony bush in California’s moderate autumn. The petal was blowing slightly in the wind. In order to get the depth of field I needed at a fast enough shutter speed to stop the motion (1/40 of a second), I boosted my sensitivity setting to ISO 640. Raise high the ISO, photographers!

In post-processing, I edited out noise from higher-than-my-normal ISO selectively. I didn’t do anything about noise in the petal or water drop areas, because diminishing the noise would have softened these elements, and I wanted them to stay crisp.

You’ll notice that I used quite a combination of macro equipment for this extreme close-up (see below). The Nikon 6T is a + 2.9 diopter close-up filter, and the 5T is a +1.5 filter. Since stacking these filters is additive, I get +4.4 diopters magnification using this pair, and relatively good optical quality in the bargain.

[200mm f/4 macro lens (300mm in 35mm equivalent terms), 36mm extension tube, Nikon 6T and Nikon 5T close-up filters stacked, 1/40 of a second at f/36 and ISO 640, tripod mounted.]
