Glowing red light leak

[shadowfox]

Hi all,

I finally nabbed a nice Electro 35 GS and is impressed by the results from it, but that's another story, right now I'd like to ask for help from the wealth of knowledge in this forum with this problem.

Check these pictures:

Looks like a massive light leak to me, it's consistently present in different intensity on 22 out of 24 frames of the test roll.

My first question is, why is it glowing red like that?
What can cause it? does anybody here have similar experience?

Many thanks!

The colour could be because light is coming through the base. If that is happening, it cannot be when the frame is in the gate, because the pressure plate will be behind it.

Does the back flex a bit on the cassette side? Might be an idea to insert a length of unexposed film, as long as will fit, into the camera in the dark, then keep the closed camera lens down in a well lit place for a few minutes. The processed strip should pin-point the leak. There should be a mark or marks to tell which end is R and which is L. Come to think of it, photo paper cut to size could also be used, emulsion to the back.

That looks like a light leak from the back of the camera to me too. Does it extend beyond the frame area and over to the sprocket holes? Does that camera have a felt/foam light seal at one or both ends of the back?

shadowfox, just noticed your post and i've just posted a similar one. my frames are not consistent though and leak extends beyond edge of frame.

oscroft: yes, the red (or cyan as seen on the negative) strip extends beyond the sprocket holes.

greyhoundman: hmmm, there's a new vertical seal at the door hinge (on the door) and also two horizontal ones (following the curve) -- one at the top, one at the bottom -- at the other end of the door.

But.... there's none on the railings in the body cavity (neither on the top railing where the film counter reset 'tab' is, nor the bottom one), shouldn't there be seals in there? I have OM bodies which do not have anything in the railings and never any light-leak, so I'm not sure...
