The Sony A100 DSLR with Minolta 100mm f/2.8 macro lens is mounted on the copy stand.
Note this photo does show the camera at the correct height, it does not show the lens at its correct focus distance of 1:1.5 on the macro scale. (This magnification is required to fill the frame of the smaller APS-C frame of the DSLR with a full frame 35mm slide.
After setting macro lens to 1:1.5, the camera is focused by moving the rack up/down on the copy stand.
Manual focus and manual exposure of 1/160 at approx f/13, ISO 100 with anti shake off is typically used.
A remote cable release or the 2 s self timer should be used to eliminate any vibration.
