filmstrip, film_strip, film_reel, film
- alias filmstrip -> film_strip.
- film_reel mass edited to filmstrip; it seems misapplied -- for me film_reel conjures up images of a large spool of film that goes into a movie projector.
As for the film tag, imho it can be kept distinct from film_strip so that the former refers to the actual object (a roll or strip of film) appearing in a picture, whereas the latter is the visual effect where the film strip pattern is used as a border to frame pictures.
But seeing as there are so few images in these tags, collapsing all of them together is also a viable option.
