I'm glad to see that this thread has been resurrected after a period of quiescence. The stories are interesting. I am a retired pathologist whose photography is now entirely for pleasure. I first started photography in earnest in 1968 when I was a general medical officer in Viet Nam with the Marines. Nikon equipment overseas was cheap; I bought the Nikon Photomic FTN for $100 and a number of lenses. I photographed military operations, mostly on Kodachrome 64. On completing military service I was in an internal medicine residency for 2 years and took pictures of patient lesions.
I then went into pathology at a large university hospital in Chicago. We had an unused dark room with a Polaroid MP4 copy unit with 4*5 inch large format camera, a Polaroid back where I could take 4*5 images with film that produced a negative as well as a print. We had a light head and I could also use the unit as an enlarger. There was also a large drum print drier. For 35 mm I could attach my Nikon. I used these to document a friend's PhD thesis as well as other research work. For photomicroscopy, I had access to a Zeiss Universal Photomicroscope with a full range of bright field apochromatic objectives, phase objectives, and dark field capability. I took thousands of photomicroscope images over 8 years.
For photographing gross specimens we used a custom built stand with an illuminated blue background beneath the glass specimen support. For illumination we had quartz iodine bulbs filtered to daylight with dichroic filters as well as crossed polarized filters to eliminate reflections. Again, thousands of images over an 8 year period. I also did electron microscopy where the images were captured on large format monochrome negative film which were placed in hangers and developed in solution tanks. It was a photographic nirvana.
This photography was technical with little room for artistic development. Since retirement, I have been trying to learn composition and other artistic skills. My photography now is at the local zoos, landscape shooting, and shooting at the wonderful Chicago Botanical Garden. I have also gotten into macro with focus stacking. I went partially digital in 1987, scanning transparency film with a 4000 ppi dedicated scanner, processing the scanned images in photoshop and having the scanned images printed commercially or later printing on inkjet printers. My first digital camera was the D70 which I bought in 2004. Since then my work has been entirely digital. Because of my scientific background, I have always been interested in the technical aspects of photography.
Cheers,
Bill
