I did not begin making science photographs until possibly 1976. When I was taking a histology class at Bradley University, I had to draw my observations from the class and - like most - my illustrative skills were somewhat primitive. But I managed.
Since that time I have become significantly better at my photography using a microscope. Below is a photograph made in Stockholm October 2012 of camel skin showing the hair follicles as well as sebaceous glands.
Recently I was exposed to Dr Ramon Cajal, a neurologist who practiced in the late 1880's. He was truly a gifted artist.
This next drawing is even more impressive.
