marcus carlsson Posted June 4, 2006 Share Posted June 4, 2006 Hi, My A12 started to leak light for a couple of weeks ago. <br> I bought a light trap package from the bay and I have changed the light trap. <br>However I still have light leak and it's in the same place as before, so I find it hard to belive that the trap was wrong (eventhough the trap was really broken so it needed a fix anyway, <br><br> But I wonder if anyone of you have had this problem and how should I find it? <br>NB. I don't get the leakage in every frame, but say 5 frames out of 12 (in an irregular pattern). <br><br> As you see the leakage is all the way out and comes from the side where you has the light trap. <br> / Marcus <br><br> <img src="http://lellou.com/photonet/leakage.jpg" /> Link to comment Share on other sites More sharing options...
grinder Posted June 4, 2006 Share Posted June 4, 2006 Looks like a processing mark as if the film was creased. Link to comment Share on other sites More sharing options...
marcus carlsson Posted June 4, 2006 Author Share Posted June 4, 2006 Donald, Since my last roll had 8 bad images (in a row, starting with number 3, so the last image didn't had any) I don't think it's the Jobo's fault. I'm started to think that I may have a light leak where you put the inner part togeather with the outer one. I'm sorry that I don't have an image right now, but I wonder if one should change the light trap there too. / Marcus Link to comment Share on other sites More sharing options...
hasselblad technician Posted June 4, 2006 Share Posted June 4, 2006 This light leak could be caused by the light trap shield (the part that holds the light trap in place) if it has a crimp or a dent in it. You should check the shield to make sure that it is perfectly flat, with no cracks or imperfections.

marcus carlsson Posted June 5, 2006 Author Share Posted June 5, 2006 David: I will check this later today, but my main question about this is that the film has a mark all the way out on the very end of the film. And what I think, is that the outer end shouldn't be affected by this problem, or am I wrong? / Marcus Link to comment Share on other sites More sharing options...
q.g._de_bakker Posted June 5, 2006 Share Posted June 5, 2006 Marcus,<br><br>You're right. The edge of the film is covered, and can not be hit by light seeping through the dark slide slot.<br>That, and the fact you already changed the seal, suggest you need to look elsewhere to find the fault.

stefan heymann Posted June 8, 2006 Share Posted June 8, 2006 The "usual" light leak can be seen on the opposite side (the one with the "V" marks): the light that comes through the light seal slot gets reflected and diffused on the film. The light seal itself is above the film surface so this is not light coming through the slider slot. If it is light, however, it comes from the same side as the slider slot. *But* shouldn't it come in a right angle then? Marcus, did you take a close look at the film? Is there really no mechanical damage to the film like a bend? Link to comment Share on other sites More sharing options...
