I'm Ben, a learning camera assistant who chose not to study film and is now catching up on production etiquette and techniques!
I recently pulled focus on a short film for a great DoP (Tansy Simpson) here in London and at one point she asked me to push the iris to a 'two plus'
Now i assumed this meant something like a t2.1, or did it mean 2.5? I'd love to get clarification on this as I was too worried she might think I was an amateur if i asked!
Thanks in advance for any help offered,
