Recently got back a roll of processed film where a sticker used to identify the negatives was placed directly on the last/first (?) image of the roll. I inquired about this, as it left a permanent marking on the negative, and they said it was because I wasn't accurate with my film loading. He said that if it continues to be a problem, that I might crank the film half an inch past the the film-loading stop arrow. Is this true? Can anyone comment on this? I'm shooting with a Yashica Mat 124G by the way.
