In my refrigerator has a old 110 film what is Kodak GOLD 100, in last weekend l decision use it, and then processing at home. The film expired in 2000, and my 110 camera is simple l can't control shutter speed or aperture, so pushing is only choice. The developing had doubled time, and the consequence is the negative has a horror particles.
These are 110/135 reel form a old Yankee developing tank and cassette.
Considering that you're using 15 year old film, that's not bad. Especially considering the negative size of 110 film, some grain would be inevitable in my experience.
