    film holders vs film hangers vs film carriers vs ... ?

    A film holder is used in the 'taking' camera

    A film hanger is used to process film and perhaps for drying

    A film carrier holds the film in position for enlarging

    A contact printer holds film to paper for...exposure

    A slide may be mounted or not, for projection or scanning or ...direct viewing...IRL

    please add any other confusing terms when using film

    For 35mm: I was corrected by someone on APUG/Photrio on my haphazard use of canisters vs. cassettes. The canister, as he told me, is the (usually plastic) box that the cassette (the metal one with the felt light trap) comes in.

    On slides: a slide is only a slide when it's mounted; as long as it's not mounted, it's a transparency. Every slide is a transparency, not all transparencies are slides.

    Emulsion vs. coating layer: an emulsion is the (usually light-sensitive) material, and it's coated in layers. But not all layers are emulsions in the strict sense. Some layers are e.g. antihalation layers, and are not technically part of the emulsion. Emulsion itself is a rather unfortunate word choice from a chemical/physical viewpoint, as technically a dry emulsion isn't really an emulsion (I think...), but simply a solid (and in this case a compound).

    Speaking of antihalation - there's the anti-halation undercoat (AHU), but also the possibility of anti-halation dyes in a multifunctional coating layer, or even a remjet backing.

    The rebate is the non-usable film area, oddly enough, which seems entirely unrelated to the strict definition of what a rebate is (i.e. either a refund, or a recess in e.g. a wood carving). In roll film, there's also the 'leader', which is often referred to as (part of) the rebate itself, although not all that is called 'rebate' is actually the leader (and/or trailer/trailing end?).

    Then there is sharpness, detail and resolving power, which are...well, I'm not even going to go there. We don't need WWIII.

    Wash vs. rinse - at what point does a rinse become a wash step? Or is a very brief wash step in fact a rinse? I'll leave this one out there as well.

    The 'dyes in color film' are only dyes after processing. Before processing, there's only dye couplers. At least in the emulsion...

    And there's probably more...

    Thank your creator that you do not live in Germany. There is "Schärfentiefe" and "Tiefenschärfe". The rest is regulated by Stroebels / Zakia's "Encyclodedia of Photography" ...

    When does a sheet of film become a negative?

    135 film is another term for 35mm film. I think. Some old boxes say "135" on it but it doesn't designate the size of the film. 35mm is the size of the film is that correct? I think 135 just means the type?

    A "negative" is called a negative because of the reverse image. That we all agree.

    But I'm used to calling slides "positives" cause it is a positive image, and that's how I called it when I worked in this business. Anyone remember "Wes-mounts?". I used to hot glue diaper pins on the back of them, cut out contact sheet image, put it into a "wesmount" and pin them on a lapel. I wonder if I can start an Etsy business....hahahaha.

    Sometimes I call lens hoods "gobo". BAsically it just shades the business end of a lens.

    About 10 minutes after it discovers social media.

    ... I would say after it's been developed, but I'm an amateur. Or an armature, if I'm using auto-correct.
