These were taken in the mid to late 1990s and early 2000's.
Mostly with one of the first digital cameras to hit the market, the Sony Mavica, which recorded photos (about 15 at a time) on a floppy disc.
The others were taken with a thirty year old Minolta 35mm my father used when he was a teenager out at DIMS an Green Valley, which I used until 2002 before I switched to digital.
