    George,

    I have a little gizmo for working out the exposures for large F stop numbers like F150. Very easy to use and I find it great... Let me try to make one for you

    I use Ilford HP5+ for my pinholes. I rate it at iso 200 and dev in xtol or id11.
    ID11 seems to produce the better negs for print for 4x5 pinholes. My times in ID-11 are 1+3 for 13 mins. NOTE: I only ever shoot pinholes in bright light. At F132 which is near F150 this gives me an exposure time of between 1 and 10 seconds but its normally 4 seconds (these times include reciprocity failure). My two reasons for using HP5+ are that its available in Gunns at a good price and it also has lots of exposure latitude

    Have fun

    Martin,

    That's very useful information about the film.

    I don't want you to go to too much trouble on the exposure calculator but if you feel that you could put something together for me I would be eternally grateful.

    I'm looking forward to this now!
