How to post-process traditional film photos?

At that time, the traditional film enlarging and developing photos was a very mature technology. The people who master this technology are technicians, but because of the development of digital technology, they are on the verge or no longer exist.

You're talking about removing a person from the photo directly. This is one of the most commonly used techniques in darkroom technology, that is, when the film is enlarged, masking, partial shielding, virtual connection, multi-bottom splicing and synthesis, etc. These methods can achieve realistic results, but these operations are very fine work, and only senior technicians can complete them perfectly, which shows the status of darkroom operation technicians at that time.

As a darkroom technician, I have many skills, some of which are kept secret. Common techniques, such as nesting, multi-bottom stitching, mask making, superposition, midway exposure, degraded interval exposure, color separation, bottom turning, local contour line, relief and mesh; Each technician has his own unique technical means to make imitations of prints, sketches, pencils, plasters, etc. And communication will not be in full swing, just as mysterious as esotericism. This is the characteristic of that era.
