Thanks for the info! The film that came out blue is Arista EDU Ultra 100, i.e. rebranded Fomapan, so the blue plastic makes perfect sense! And as for the R09, I have very little experience developing film, but the R09 seems like a very nice and easy to use developer. I did however have a roll of Acros come out particularly contrasty this afternoon, but I am also using a new, panoramic pinhole camera and I don't know very well yet. Still playing with getting the exposure times dialed in.
