Dear all,
I have a basic question but found until now no clear answer to it. I use a exposure time of 15 sec at f:11 to print by projection my 4x5 step tablet on paper with a ratio of 1:1. Is there any factor based on this standard time I can now use to print in larger sizes ? Thanks for your help. Regards, Philippe |
