I am a retired Army Lieutenant Colonel, and Vietnam combat veteran. Here is a sample of some of my photographs. I currently am using a Nikon D750. Prior to digital SLR's, I used medium format cameras and I had my own color darkroom. When digital cameras first came out I never thought they would reach the equivalent of film. Now with SD cards of 64 gigs, it's a huge savings from film! Keep pressing that shutter gang.
