Russian Jack Springs Park in Anchorage, Alaska starts to get green in late April. Golfers start using the park’s greens at about the same time even if there is snow on the ground. The local scenery was still looking drab this spring so I concentrated on macro photography. Close up photography has to be sharp to be effective. Movement in macro photography is accentuated so even insignificant camera vibrations or slight subject motion can produce soft images.
The used my Nikon D600 and 105mm f/2.8 micro lens with a tripod to take these close ups. The lens produces very narrow depths of field. For example, the Tree Stump-1 image was shot at with a f/3.5 aperture. The sharp in-focus range was probably around 1/10 of an inch. The Tree Stump-2 photo was shot at f/14 and had a sharp image depth of around ½ inch. The green leaf images required numerous shots to acquire sharp focus as it was windy and I had to wait until there was no subject motion. I used homemade clamps to secure the stems of the leaves, but even small subject movement is detectable at close ranges. I also used white reflectors to add brightness to the leaves so faster shutter speeds could be used. Acquiring sharp macro images takes time and good technique. Close ups may look sharp on the screen until you enlarge to image to a 2:1 or 3:1 ratio. At these zoom levels you see detailed noise levels and chromatic aberrations. Lack of sharpness is not really that apparent in web images, but with large prints imperfections can be obvious.
