Many microscopists have at least one microphotograph in their slide collection.
I have just the one. However despite there being an excellent book on the greatest producer of them, J B Dancer, I cannot find mine listed. The actual microphotograph is 1.9mm by 1.7mm on the microscope slide. I took it using the Zeiss Universal and a x2.5 Plan objective onto Fuji Velvia. The slide itself has the usual J B Dancer label, but without his name or initials.
