It's not well suited to pinhole, at least without super bright light based on using a box of the stuff myself. It gets a greener cast with longer exposures. A metered time of 4 minutes will go off the scale in guestimated exposure. Some pinhole camera's film holder backs aren't big enough for the pa-45 holder as well. Try it with a normal graflok equipped camera and pinhole lensboard if you need to try before you buy/build a pinhole.
