I went and shot my second roll yesterday. I ran into an issue, seemed to be in portrait, where sometimes after I took a shot it wouldn't let me advance the film. I gave the troublesome pin another lighterfluid treatment and ran it through a roll of backing paper...flawless in landscape...jammed once in portrait. When I looked at the images from yesterday four didn't get exposed at all (probably the result of the portrait jam), four were perfect and I had two double exposures (again, the jam). They're drying now...I think the second treatment helped a lot...I'm considering doing a third since the pin action improved noticeably each time. Thoughts?
