Help identify what caused this light leak

Does anyone have any ideal of what caused this light leak? After I developed the film I tested my bellows and they were light tight, and judging by the negative the leak did not happen while the negative was in the film holder, but im still not sure what happened.

I developed this using the taco method in a 120 daylight tank if that helps at all. Anyway here is the shot, thanks for the help.

Wrong forum, sorry guys. Mod's if you could move this to the Image Sharing & Discussion forum.

Thanks

Was the center tube in the roll film tank before turning on the lights?

Sure looks like a meteor strike to me. You didn't feel a heat flash and hear a large boom while exposing the neg?

My tank does not require a central tube.

I guess i should check for meteors falling next time i take a shot ha!

THat's a light leak immediately before or after exposure, while the dark slide was out.

At the top of the picture, you see the light going a little bit beyond the rebate made by the holder. At the bottom, the main light starts a little INSIDE the edge of the rebate. That means that the light entered at an acute angle from above, while the dark slide was pulled.

I think you have rattled the holder too much while pulling or inserting the slide. ;)

Guess how I know. :D

I agree with Ole -- definitly while the film was in the holder and probably just as the darkslide was removed from the holder before taking the image. The darkslide was probably pulled back a little upon removal (only because we tend to be a little more careful re-inserting the darkslide).

How strong are the springs holding the back on? If they are weak, you might want to keep your thumb pressed against the GG as you remove and re-insert the darkslide as a precaution.

I do recall that the dark slide was being stubborn when I was reinserting it, my springs are not that strong ether so I will keep that in mind from now on.

Thanks guys!

Also -- stubborn darkslides can be appeased with hand rubbing with a cotton cloth, or if that does not help enough, a slight spray of furniture polish and a good buffing.

PS -- When I lay the darkslide down to buff it, I use a little paper to even out the height difference between the darkslide pull/handle and the darkslide itself to keep from stressing it.

It can be helpful to place your dark cloth over the top of the camera when removing and inserting the dark slide.
