Choice of film
I read recently in a newsletter from Firstcall-photographic, that Fuji are ending deals to manufacture film for other suppliers. So when existing stocks run out, the only way to buy a Fuji film will be to buy a roll that actually says Fuji on the label.
The way I use the cheaper films is just to use them when first testing out a new-to-me old camera. Once I can be sure there are no light leaks and the shutter, aperture, and wind-on mechanisms are working, better quality film will be used. I don't use film cameras to save money and increasingly believe that if an image is not worth using a first-tier film on, it probably isn't worth pressing the shutter.
