Hey everyone. I am a newbie when it comes to shooting film. I recently bought a holga and have a roll of 120 in there now. I was wondering if 120 film has a leader such as 35mm. I am wondering because I was going to do the strip of film in the fixer test to determine my fix time and also find out when the fixer has exhausted. But since i am a college student and cutting up a fresh roll of film seems like a crime, i would much rather take a leader off the roll I am currently shooting while I am loading it into my developing tank. but does 120 film have a leader? and if so will i be able to tell where it is in the dark? exact film I am using is ilford delta 400. and i will be using ilford rapid fixer. thanks.
