What is that black film on plastics in your home? i.e. the plastic drawers in your frig, the plastic storage binds in kids rooms, electrical outlets where air freshners are plugged in? It wipes off fairly easily almost like a smoke film. . .
I don't think I have ever seen that phenomena. I wonder if anyone else has.
Do you smoke?
Smoking leaves a yellow stain on things; I have yet to see some one, even me, smoke inside of the refrigerator.
BTW, what does this thread have to do with photography?
This is a photography forum. When we refer to film it is what was used for photography and put inside a camera to take a photograph. That was before digital cameras were invented. A lot of us still like to use it with our older cameras.
Over achievers make the rest of us look bad.
Do you live in a coal mining area? Or, do you live in an area where a nearby plant or factory burns coal? That's the only thing I can think of that could leave a black film on your plastic shelves. Yet, coal burning leaves a kind of gritty, black film, so your problem may not stem from that.
As others have pointed out, you've really come to the wrong place to ask your question, but, what the heck, it's always fun to try to come up with an answer to any question.
With that thought in mind, can anyone else think of other possibilities?
It could be Fujifilm Velvia 50. Okay, I know I'm not helping but I had say it before someone else did.
I am a photographer, I don't deal with realism. I leave that for the poets!
OK, here's my best shot on making this film related.
A one time Seattle Film Works (?) respooled Kodak movie film, which is BTW, how 35mm film originated.
this film has a BLACK BACKING which had to be removed via aspecial process before it could be processed as negative and/or slide film.
There were thise who swore by the stuff, but because it was meant for PROJECTION at 60 frames /sec (?) it did not have to be critically sharp.
It was the film film that NYIP said to avoid like the plaque in their lessons.
I see it also on the inside of the car windshield and windows
my best guess is, it is vinyl beirng redeposited after outgassing from various liners, insulation, component materials and such. and you are right, we see it where there is electrical current flowing. my guess on that is that there is some bond breaking being induced at the molecular level.
to bring in the photography aspect again, that instability is one reason vinyl slide pages went out of common use.
Mischance nothing, thus idle woe...
Photography is not about how much camera you bring to the shoot.
The stuff around your receptacle and switch plates is dirt being forced out by draft. Remove plates clean carefully around the edges, then buy air thin foam- insulators from hardware store and put them under the plates and screw back on. These also help drafts that suck up heating. The stuff around air outlets is the same. Many companies offer cleaning the ducts for better efficiency and dust bunnies. Clean filters in air conditioners and wholee house heating vents.
