1 roll = 3 artists + 1 dog
There was once a time I would shoot and process literally hundreds of rolls of b&w film a year... Nowadays nary a roll ever passes through any of my old, dusty cameras, well, with one recent exception--I did have some Tri-X in my trusty Yashica-Mat, and it sat mostly in the studio for a few months. During that time I did manage to grab shots of three artists who have shown at the gallery this year, as well as a quick sitting with Fritz:
Three portraits and one dog--not a bad shooting ratio for a roll of 12 shots. Put that on your 16GB card...
