I had just acquired a lightly used Minolta 600 f4, and went to a nearby provincial park with it mounted on a Maxxum 9xi and a heavy tripod. I was using Fuji Velvia 50 slide film.
Wanting to do some test shots, I set up on a river bank and focussed on some interesting plant life on the opposite bank in the warm early morning light.
With that, this doe and fawn walked into the picture as if on cue. You don't get that kind of luck very often!
