These photos were taken with film.
Many moons ago (high school) when I first began learning photography it was all film.
The digital options weren’t high enough resolution or capable of producing the quality they are now (I have some of them in my camera collection, two of them use floppy disks). After a while film became expensive and I set it down. With the somewhat recent resurgence of film I’ve been known to, on occasion, load up one of my old cameras and shoot some frames.
