Flimsy film sheets in a darkroom bag ...

I decided to buy some Rollei RPX 25 in 4x5 sheets. I want to expose them in a camera with a barrel lens, so keeping the ISO low was a good idea, I thought. But the sheets ... well, they seem quite thin, indeed!

Even the much bigger 5x7 sheets (Foma and Ilford) feels like cardboard. Can't remember 4x5 film being so thin?

Probably because the rollei is some aerial film
Masquerading as real film with a high price tag
Fp4 is NOT thin. Use a real film and a neutral density filter for longer exposures

Yeah, I should have remembered that the Rollei is repackaged stuff ... and I should have known better, actually reading up more on the specifications.

The ND filter is a good idea, didn't think of that - thanks for the reminder.
