The Altissas are
beautiful cameras. Made by Eho-Altissa in Dresden, Germany. My Altissa
- Box Nr. 200 (1936 II) hails from around 1936. 
The Altissas take 120 film, which is hard to believe. They are barely wide enough to take medium format film. The shutter speed is marked 1/25 and the lens is an f8 Rodentock Periscop Altissar. Forget the sunny-sixteen rule with this camera.

I used a #25 filter
for these shots. I couldn't find my ND filter and it was a
sunny-sixteen day.
The exposed roll was loose and fat. A sure sign of film flatness problems. I'll try to tighten it up in the future.
