i would use the whole roll easily trying to get what i needed. at first i thought, this is insane 24 exposures for 1 view
but then it was go-time and i had to deal with cranky people bad expressions trying to coax something nice
different poses, different scenarios and i sometimes went into a 2nd roll. when i worked for the portrait photographer i allude to
she would give me 3 full holders of split 5x7 film ... 12 exposures / client/sitter.
it isn't machine gunning by any means but it certainly isn't 10thousand exposures ...
