One of my favorite characters in fantasy literature, J.R.R. Tolkein’s Smeagol, would have appreciated the nice, plump and juicy slab of fish I brought back from the store. The fish meat rested on skin on the back, and the skin and scales glistened with a rainbow of pastel colors in the light. I knew I had to photograph the fish scales up close and personal.
I used my 85mm tilt-shift macro with a 36mm extension tube at an effective aperture of f/51 and an exposure sequence at ISO 100 from 1/8 of a second to 8 seconds. This is extreme close-up photography, with a magnification ratio of about 15:1, meaning you are viewing the fish scales fifteen times actual life size. Magnified this way, the fish scales look almost soft, and could be barnacles, or schools of fish themselves.
Smeagol a/k/a Gollum would probably not have approved of my light source: directed sunlight (Gollum preferred dark caves, and the sun hurt his eyes). He also might have thought that the way it was prepared (by smoking) “ruined” my nice, plump and juicy raw slab of salmon. But I, to use Gollum’s vocabulary, thought my nice piece of smoked fish was “tasty” indeed—when I ate it after photographing it!
