Hello,

I have just built an 11x14" back for my Sinar P system and am eager to try it out, I have 10 sheets of Arista APHS litho film here and am keen to shoot some portraiture...

My plan is to pump 4x 650W open face lamps onto the subject from about 700mm away (a crude ring light of sorts) and shoot at around f11 to get full coverage with the lens I am using at the 1:1 magnification I want...

(Either that or two 1k profiles from each side to make the most of the output)

Not sure of the exposure yet, but to keep exposures down I thought that pushing the film may come in handy - development time and concentration being my 'free variables' here - I'd use D19 or maybe Dektol if I can find it around home ...

As it is a litho film I was hoping that the increased contrast would work in my favor considering I will be printing in Pd...

Question > Am I simply too far off the scale of acceptable contrast and/or exposure times ? (trying to keep the shutter open for less than 1/30 sec)

Anyone have experience in working with Litho film contrast as an aid for Pd printing ?
