It's got to be about 17 years since I last shot colour slides for projection. I used to shoot a lot and do my own E3/4 then E6 processing, often 20+ rolls a month.
I still shoot colour transparency occasionally but only 6x9 or 5x4, although I may begin shooting 6x17. When I had to give some very formal illustrated lectures I did shoot and project B&W slides around 3 years ago and would do the same again.
