Quick question. A few rolls of my footage (7231) had a light leak and burned the film slightly. I know there are many ways of removing a light leak using a NLE program or motion graphic program but i was wondering what one would be the best to work with grainy B&W film. Here is a low resolution still scanned from one of the negatives.

Could a layer mask possibly work given the right paramaters?

Hi,

If you have a frame which is black with the light leak showing over it, you could possibly try to derive some kind of matte to multiply back into the original image. Otherwise you'll have to draw the matte yourself, which could be tricky, and I don't know that you'd ever get it quite perfect. What's more, if you have any change in the artifact - perhaps as the camera was moved against the ambient light - the streak will change, and you'll have to try and change with it.

Not that easy, but worth a shot.

Thanks,
It remains relatively constant throughout. I'll try that.
