To give you a hand, Richard Photo Lab whipped up a little quick-reference blog defining some of the foundational elements of film formats! Use it as you start experimenting with film, or if you’re in need of a few refreshers (plus some additional deets you may not have known). Even if you’re a seasoned pro, it’s easy for the basics to escape you as your focus shifts to developing your artistic vision. If you’re new to film photography and just starting to dabble in the wonderful world of film, there’s a lot of foundational knowledge and jargon about the medium you’ll want to understand.
