This miniature is about 1 inch (25mm) tall

The lens I took the shot with is a 35mm f/1.2 projector lens from the Soviet Union

The focus was incredibly hard to nail due to the lens having no aperture control so the depth of field was so small that in this image of you look closely you’ll see his ear is more in focus than his face.

If there’s any more questions I’ll happily answer them.
