The Vredeborch Felica looks like a box camera, but it has a full compliment of controls. I decided to give them some exercise by loading the little camera with some Tri-X. A 400 speed film is a bit of a stretch for a simple camera with a 1/50 top shutter speed, but I thought the use of the built-in yellow filter would get me close enough to the right exposure on a slightly hazy day. I think that was a correct assumption; the shots I got were within the film's wide latitude. Still, I think I prefer my previous results with 100 speed film.
