Monochrome

I
have used the following formulae from the Rayco Formulae Book (if you don`t
have a copy of this you don`t know what you are missing. I think it`s as
much value for money as our CRC subs!!)
It allows you to produce slides from Negative Print film. I have
found that the best results are obtained by using the film at three (3)
times its rated value. However you can carry out your own personal tests to
get your preferred results.
