Can anybody tell me if there is any way to operate the Yashica Mat LM shutter with the back open?
I just got a shutter speed tester and have been checking my large format shutters but can't figure out if there is any way to check my Yashica.
Thanks Dan - I just got the camera and still learning about it. I didn't realize I needed the top spool in place as well but it looks like we're good to go now.
