Q: 5. I don't understand the FPP instructions on loading the sheet film holder; the emulsion is doublesided; is there a preferred way?

A: According to the manufacturer, the Film Photography Project Black and White Negative X-Ray Film (4 x 5", 25 Sheets) is notched like traditional 4x5 film. That being said, as it has double-sided emulsion, you should be able to load the film in any direction. As the film is blue-light sensitive, if you so choose, you may visually load and unload the film in a darkroom under a red safe-light such as the Delta 1 Brightlab Universal Red Junior Safelight 11 Watt, B&H # DESLJ. https://bhpho.to/3Issmhv

Q: 6. is it a fresh film?

A: B&H buys and sells film in bulk. In general we regularly maintain fresh film stock. All of our film is at least 6 months from expiration (typically much longer). Anytime film stock is less than 6 months from expiration we sell it in a separate section and label it as short-dated film and also price it with a slight discount (again due to the volumes we sell this rarely occurs). Unfortunately we do not have access to our inventory to hand inspect the expiration date of any of our films prior to purchase.
