I want to use Fujifilm Neopan 100 Acros with long pinhole exposures. The online calculator I use doesn't have data for this film. Where can I find information? My pinhole is f200.
Thanks

Can I also suggest checking out the FREE PinholeDesigner tool?
http://www.pinhole.cz/en/pinholedesigner/
This calculates reciprocity for a range of films.
For 100ACROS I used this tool to output times without adjusting for film then doubled the exposuretimes for metered times 120sec or more!!
