Hello all,

I was a projectionist for a couple of years during my student days. Boy, 
could I bore the whole list with reminiscences! However, hands-on experience 
and training under a skilled person cannot be recommended too highly. You 
electronics people who have to wait for an image to form, bah! We just pulled 
the film down one image and flashed twice (Ernemann 1923).

Kind regards,
