I remember watching a series about 15 years ago... I think they may have been done by Kodak... Basic darkroom practice etc...
It sticks out in my head because the guy in the video said "WARSH" a lot... It was the first time I had heard it said that way "Warsh the film for..." and it struck me as so odd at the time.
I remember that I borrowed them from my local library here in Windsor.
