gregory_imler Posted February 23, 2017 Share Posted February 23, 2017 Hi all, was curious if anyone has ever seen a similar occurrence as the one in these images taken with FP100c on a Polaroid Land Camera. It's a modification that removed the original 114mm lens with a Tominon 127 f4.7 with the Copal press shutter. This circle of light only occurs in the last couple of images in the pack, and I don't see any light leaks otherwise. Is this possibly an issue with how the film was loaded? Thanks in advance!

john_shriver Posted February 24, 2017 Share Posted February 24, 2017 Looks like you have a pinhole light leak that only "fires" when hit by the sun. Link to comment Share on other sites More sharing options...

I'll try some shots with sun or direct reflection in them and see if that aggravates the issue. Looking back at the rest of this pack, no other shots dealt with that sitaution so I'll experimen.

gregory_imler Posted February 25, 2017 Author Share Posted February 25, 2017 Used a small key chain light last night that I was able to put just inside the camera body with the bellows extended out fully. After a few minutes to adjust to the darkness, I did end up seeing at least three pinhole leaks at some of the corner points in the bellows. Something about how crisp the circle was made me think it was something else other than a light leak. Thanks for the insight! Link to comment Share on other sites More sharing options...
glen_h Posted February 27, 2017 Share Posted February 27, 2017 An inadvertent pinhole camera. The popular problems with pack film are due to dirty rollers, or not pulling smooth enough, which have known patterns. -- glen Link to comment Share on other sites More sharing options...
rodeo_joe1 Posted March 1, 2017 Share Posted March 1, 2017 Looks more like that press shutter was tripped with the lens folded back against the film to me. A pinhole would create a much smaller image of the sun and in the form of a smeared trail. 1 Link to comment Share on other sites More sharing options...
glen_h Posted March 12, 2017 Share Posted March 12, 2017 Tripping the shutter while folded could make an interesting pattern, though I would have thought the circle would be more centered. The Polaroid pack cameras that I know of, with electronic shutters, don't power the shutter when folded back. Helps save the battery, and also reduce accidental exposure. (I believe that the shutter doesn't open, as the electromagnet to hold it isn't powered.) I was trying to test the battery without opening the camera all the way, but the test doesn't work. But if you replace the shutter, that protection goes away. -- glen Link to comment Share on other sites More sharing options...
