View Full Version : Light leaks on Polaroid 8x10 holders -- help!
I have six fairly new Polaroid 8x10 holders but they all seem to leak light. Using a flashlight into bellows I can see the light leaking out of the slit where the film is held (the slit holding the darkslide is light-tight).
I can even load a holder, shine a flashlight along the side, and fog the film that way.
The holders are in pristine shape and I can't see a thing wrong.. any ideas?

While there might be a gap when the holder is empty, if you have film in the holder the path for light ot get in should be blocked. A silly question, but you ARE using Polaroid materials in the Polaroid holder aren't you?

Which type of holder are you using, Mark?
On my 81-06 holders, there are light traps along both sides, and felt traps at the bottom and dark-slide ends. I'm not sure how the older 81-05 holders are constructed.
You might check the long side to see if there is any warpage which might defeat the light traps along that edge.
Yes, I am loading the holder with Polaroid film before doing these tests. Like I said, a properly loaded holder + flashlight fogs the film. When I load it into my camera, pull out the slide (until the blue line), and shine a flashlight into the bellows I still see light leakage through where the film is.
Ralph, these are the new holders and appear to be free of warpage..
:confused:

Mark, am I correct in assuming the leak is coming from the long side that opens? Or, is the leak at the bottom (the end opposite from the dark slide)?
The leak is coming from the side of the holder where you insert the darkslide. If you look at the holder slideways, there are actually two slits -- one for the darkslide and one for the film. The light is leaking in the film one, even when loaded.
