I used to buy it in 100 foot rolls and then "Roll my Own" I kept a supply of Reloadable Metal Film Cassette for Bulk Loading around just for reloading. Then shoot and come home and process the film and then print contact sheets and pick and choose the ones to print with a loop. Then print.
So much easier to pick up my Nikon D7100 (The best camera ever made Bar none) shoot and load into the computer and process with Lightroom and Photoshop and post online and all in the time it took to Roll the film and get it in the camera.
