I have about ten years of experience in three different labs printing other folks B&W negs... many years ago. After awhile I grew tired of it but I did learn a lot and I grew very appreciative of my own negs which were developed and selenium toned very carefully to print on either #2 or #3 Ilford Gallery... #3 about 90 percent of the time. I don't intend to toot my own horn because I appreciate all well-exposed and developed films. It's just that in all those years not a singe customer controlled their film processing. All the individuals who did also printed their own work so I never saw their negs.
