At the end of the day in my office, I was about to swat a sleepy November wasp on the window-shutter when a small spider, a quarter of the size of the wasp, ran up to it and threw a single line of silk over it. I thought the wasp would break away instantly, but it was not able to. I quickly got the 100mm macro and 1200 ringflash (with adaptor for the Sony A100 mount, and no possibility of TTL) and got some shots at the correct exposure, f32. I knew these would not be sharp. The 100mm loses sharpness rapidly as you stop down further than f11 at 1:1, and at f32, hardly any detail is present. I was shooting raw .ARW files so I opened up to f18, which is acceptably sharp, and took some further shots as the spider expertly avoided the wasp's sting and kicking legs, and bit it (apparently on the eyes, which would be soft and unarmoured). The bite paralysed the wasp, which was then wrapped lightly in a few more strands of silk, and hauled over to the hinge of the shutters. Two hours later the spider was still feeding on a much reduced wasp. The raw image needed -1.25 exposure in Adobe Camera Raw 3.6, plus some post processing with unsharp masking and a vignette to hold the subject in. My master file has no vignette added, but does use negative vignette control in ACR to darken the edges (which the Macro Flash 1200 tends to overlighten). This is slightly cropped from the full image.
