Hi... I developed a 35mm film in a lab and the negative is all stained with little spots (which appear white on positive). The film is a boxed Kodak. I show you an image. The stains are on the negative, the problem has nothing to do with the scanning. It seems like a process mistake, bad washing or something. I know almost nothing about film developing. I always develop in labs and this is the first time something like this happened. Well, in fact, the second one. In the first one, a B&W film in another lab, there was an evident intrusion of light during developing, and also the film was stained with little spots of the same kind. Do you know what the mistake was, technically? Is it a mistake that an experienced lab could make easily? Or is it about complete negligence?
