<p>Yes,<br> it'a an older Pro back. I have a Pro S body and film back, this older one was picked up off ebay. <br> It is the side near the hinge. I'll take a close look at the seal. <br> But, when I did the internal light check, I found light leaking out from that gap between the metal plate and that roller - odd. Was wondering if an adjustment, or something, was needed. </p>

<p>I have an older RB67 film back that has a vertical light leak. I redid all the seals with the Asahi kit but still have the leak.<br> <img src="/photo/17818324" alt="" /><br> http://www.photo.net/photo/17818324<br> The shot was a long exposure (3 - 4 minutes) with a welder's glass over the lens. The light leak is always in the same position, and shows even if I have a very quick exposure (even 1/1400). <br> The leak is from the older film back, not in the camera body - I've checked the bellows and they are sound. When I shoot with the newer film back I do not get the light leak. <br> A poster on another site said to put a small LED flashlight in the filmback in a dark room. Brilliant idea. I did this and saw a thin line of light in the area circled in yellow. (when the dark slide was in place there was no light visible anywhere from the film back. <br> <img src="/photo/17818325" alt="" /><br> http://www.photo.net/photo/17818325<br> And opening the film back shows the area in better detail -<br> <img src="/photo/17818326" alt="" /><br> http://www.photo.net/photo/17818326<br> The light shows through at the gap between the film plate and that large roller on the right. There is no foam or light dampening there - very confused as how light can leak through here. </p> <p>Any suggestions on how to fix this?</p> <p>Peter</p> <p> </p>
