We built a florescent tube exposure unit and are having some problems. For all you other people who built such a thing:
What kind of bulbs are you using?
What kind of positives are you using.
What kind of emulsion?
How far are your lights from your glass?
How long is your exposure time?
How thick is your glass?
I know there are a few other factors, but I thought we bought all the right stuff but exposed at 33 minutes. 33 MINUTES! The table we used at MCAD exposed through unoiled bond in 1 and a half minutes. Help me, help others.
