Light leak?

[pamphoto]

A friend of mine just got her film scans back and she noticed this weird lightleak on her images. She has the canon f1.

What would be causing it? How can she fix it?
Thank you for your help!

This is the worst of the roll. On others it is just a spot of light like a reflection in a window.

It's white with no yellow or red rim, so if it's a light leak, it would be at the front of the camera. The first thing that comes to mind is a punctured shutter curtain. I'm not too familiar with the F1; I assume it has a curtain shutter, yes? I'd inspect it; there's probably a tiny hole close to the lower right corner when looking through the (open) back of the camera.

You do not say which Canon F-1 model we are talking about. Both the earlier F-1 and F-1n and the later New F-1 have horizontally traveling titanium shutter curtains. It is very rare to have a pinhole in one of these curtains. That's something seen with cloth curtains. If a shutter curtains has a pinhole, the light leak appears in the same spot every time. The New F-1 does have one quirk relating to light leaks. All of the caps on the bottom must be in place to prevent light from leaking in. If caps are missing then light leaks may appear in different places, depending on the angle the light rays enter.

I'll have her look. Thank you

I'll ask her which model, that is all the information she gave me.

The light spot is in the same place but, in different intensities, sometimes very small spot of light to this one which is the worst.

I'll have her check her caps too.

Thank you.

I talked to her today, and there is a tiny pin hole n the shutter curtain.
Is this something that is able to be repaired? What options does she have?
Thank you!

I once had the shutter curtain of a Nikon F3 patched.

I know of people who have used something like liquid rubber dabbed on the pinhole to patch it up. I've never done this myself, but it apparently can work and even hold up pretty long. Since the alternative would be to replace the shutter curtain and that would cost a couple hundred $$$ just in labor, I would say it's probably worth a shot.

I will let her know. Thank you!
