How to post-process traditional film photos

Traditional film enlargement and photo development were already very mature technologies at that time. The people who mastered this technology were technicians. However, due to the development of digital technology, it was on the verge of extinction or could be said to be gone.

You said that a person in the photo was directly eliminated. This is one of the most commonly used techniques in darkroom technology. When the film is enlarged, a mask is made to partially block and virtualize the photo. , multi-base splicing and synthesis, etc., these methods can achieve realistic effects, but these operations are very delicate work, and only senior technicians can do it perfectly, which shows the status of darkroom operation technicians at that time.

As a darkroom operation technician, I have mastered a wealth of techniques, some of which are still secret. Common nesting, multi-bottom stacking, mask making, stacking, mid-exposure, degraded interval exposure, tone separation, flip stacking, partial contours and other techniques, as well as relief, reticulation; imitation prints, sketches, pencils, For the production of plaster and other effects, each technician has a unique technical method, and communication will not give out all the details, it is as mysterious as a secret transmission. This was characteristic of that era.
