The old folders require a presence of mind:
1) Open, and advance the film with the wind knob.
2) cock the shutter,
3) estimate the focus distance.
4) estimate exposure to set aperture and
5) set speed.
After exposure advance film if you don't want to risk a double exposure.
Remember that a half press will lock out the release on cameras that use this method to prevent double exposures.
I have a bunch of the old folders with 120 film.
To prevent double exposures and to prevent the bellows from sucking the film away from the focus plane,
After every shot that I know will not be a double exposure, I advance the film just beyond where I can see the number in the window. NOT to the next number, just beyond the number that I just shot.
Doing this, by looking at the window, I KNOW I shot the last frame and I must advance to the next number.
By advancing the film to the next number AFTER extending the bellows, I prevent the vacuum sucking the film off the focus plane.
If I look at the window, and it's on a number, I can take the shot. If it's blank, I need to advance.
If you WANT a double exposure, you can trip the shutter, even with a double lock, with a cable on some, and by manually tripping the shutter release on the lens on all of the ones I have.
The trick is to ALWAYS advance off the number after EVERY shot.
Mine are 6x9 and 6x4.5, my 6x6 cameras are Yashica TLRs which require a different technique.
