One set of pictures has a fly. The other no fly. Each is composed of six exposures. But I made a mistake with the one with the fly and it seems that two of the images must have been in the wrong place because the end result is not sharp. However, in between exposures the fly lifted its front legs off the flower and started cleaning them. So it looks like he has eight legs. Insects only have 6 legs. In one exposure the legs were down in another they were being rubbed together. When stacked it looks like it has eight legs. The other picture made up of five properly spaced exposures is sharp all the way through. But I thought it would be interesting to show the one with the fly -- even though it ain't so hot.
I need some sort of device for evenly turning the lens focus ring in exact predetermined increments. Some kind of a miniature ratchet that can be set to advance the focus in, say, one millimetre (focus) steps. For the microscopes this is not a problem because the focus knobs are graduated in micrometres. Don Jack Davis wrote: > Don, > I only see one image with a fly.
