Prague

I'm off to Prague at the weekend and I'm taking my 10"x8" pinhole
camera with me. The plan is to shoot a combination of Maco Genius and
paper negatives, with the intent to do some Cyanotypes with the Maco.

Should I be looking to expose for longer, or develop for longer to get
an acceptable negative with the Maco film...?

Cheers,
