(1) Ah...junior high school. Used my mom's Kodak 110 camera or my dad's Fuji point and shoot.
(2) Probably Kodak colour film, don't know which kind.
(3)(4) All film developed and printed at the lab. That being said, I was really curious about the abandoned darkroom at school (literally a closet), but we didn't have a class or club I could join to learn how to use it.
