Analog film photography and cameras

Minor tinkering - painted over 1 mark in red, copied and pasted, moved to 'underline' a different mark, repeat until enough to spot a pattern.

It looks to me as though many of the white lines are repeated, i.e. same shape and size, allowing a bit for the lo-res version lifted from the page. Would force drying marks duplicate in this way? I used to have difficulties with water marks after rinsing and drying when living in a hard water area, but never in a repeated pattern.

Can you inspect the emulsion surface of the negative for physical damage? Placing it on an abrasive surface and moving it slightly might produce a pattern of similar shaped scratches at all the points of contact? If so, it could be carelessness at the processing lab...

I worked in a high street lab for a long time, and this looks distinctly like roller damage to me – the rollers in a lot of industrial C41 machines get progressively harder as the film moves through the machine, with the last being a rock hard rubber squeegey (sp?) before the film goes through the drying chamber. These squeegeys (sp?) are usually rinsed daily, but are often not. When not, they accumulate chemical build ups that cause the the wrinkle and perish, often leaving uniform areas of wetness or chemically smearing on films...

In short, change labs!
