scratched negatives

I recently took my film into a large chain (in the UK). The negs

came out with a horizonatl straight line across every exposure,

except for numbers 1 and 36.

 

This looks like a major scratch. This also comes out on the prints.

Should I complain to the developing company? At the end of the day,

there is not much than can be done to repair the film, is there?

 

Thanks

I'm not sure what you'd do to repair the film, but the least I would do is scan the images to create a digital file and clone the scratch out of the important images if the store wasn't agreeable to at least doing it for me.

a horizontal scratch across the whole thing is a signg that you got a grain of sand on the like in the your camera, for example stuck to the pressure plate. Examine the camera carefully (the inside), then clean it with a soft brush and wipe the pressure plate with a soft cloth

I run a photo lab and I can tell you that 99% of the time the cause of a scratch like that will be a film processor that has not been thoroughly cleaned.

i also work in a photo lab and would be 99% sure it's caused by a dirty film processor but us photo lab technicians do like using the 'a grain of sand in your camera' excuse ;-)
