I shoot about 1 roll per week (after a long period of time of shooting about 2 or 3). That seems to place me in the 5 or less category.
There was a time when I was shooting almost three times that much. My cameras were never empty, and my film developing bills were a bit outrageous...
And then, I discovered slide film. And my university lab! They charge $5 for doing a 36-exposure roll, and $4.50 for a 24, same day developing, plus scanning and printing (before I got my own). Great posters too!
One drawback: lab subject to state budget cuts. So far, none, but it's always a threat we have to live with.
Sorry I went OT! 🙁
