Topic: Possibly a daft question?

[Kayos]

Im about to take a friend to shoot film for the first time, 2 similar cameras with the same film in them.

Obviously i need more chemicals, but do i need to increase development time if there are 2 films in the tank at the same time?

Logic would say no, but film isn't always logical

and the answer is... no.
just make sure you have enough chemistry in the tank

Thank you

It is always better to ask, rather than get it wrong

Just make sure they are shot at the same iso
