I have just got an Iskra folder and put a roll of film through it (not yet developed). It was a rare camera in that the film counter is still working.
After I finished the roll and removed the film, the shutter is still cocked. How do I now fire the shutter without a film in (a pic of what to press would be helpful)? I hear that it's possible and I don't want to leave the shutter under tension until I use another roll.
