I’d like to deliberately produce static-discharge artifacts on a roll of film for creative effect. What conditions or handling methods make static marks more likely, and is this easier to do during shooting or later in the darkroom?

Static electricity is a plague we try to avid in the darkroom. As an old-time photofinisher, I did all manner of things to alleviate. As you know, film is taped to a plastic spool and or taped to paper backing. When loading film on reels or automated film processor, you are required to detach. Old-timers, like me, will tell you, if you rip when you detach, a static discharge occurs. If the darkroom has a rug, shuffling your feet will induce a static charge. So will combing your hair. You can experiment, rubbing dissimilar materials together like a glass rod rubbed on a balloon.
Be aware that many things like the above will induce a static charge. To see the discharge, you need to in total darkness and you need to be dark-adapted. Dark adaption typically requires that you remain in total darkness for 15 minutes or more. Also, low humidity enhances the generation of static electricity.
I spent a lot of time trying to prevent, seem weird it’s an art form.

Static marks are usually easier to create after exposure, during handling in the darkroom, than while shooting. They come from the same kind of static charge that causes small shocks in everyday life.
Ways that can increase the chance of marks:
- Handle or detach film abruptly, such as ripping film from tape or backing.
- Work in total darkness; the discharge itself is only visible if the room is completely dark and your eyes are dark-adapted.
- Build up static on yourself or nearby materials by rubbing dissimilar materials together, shuffling on carpet, or similar actions.
- Keep the film grounded while you isolate yourself, or use an electrostatic generator if you want a stronger, more repeatable effect.
In practice, the effect is associated with film handling and transport, not with the photographed scene itself, so experimentation during loading, unloading, or processing is the most direct route.
Be careful: static is unpredictable, and working in darkness adds safety risks. Also, aggressive handling can damage or ruin the film beyond the intended effect.
