Some reports of light leaks on colour and black-and-white film rolls show that the film confirmation window in some cameras can cause repeated fogging over the entire roll’s length. This is not caused by poor light seals, but rather by light piping through the clear UV coating on the film label. To prevent leaks from showing on your rolls, cover the film confirmation window up until light-tight.
NOW100 and discount rolls are unaffected by this issue. From 1 Sept. 2022 for Vision3 500T, and from 21 Oct. 2022 for Vision3 250D, Vision3 film is shipped with labels that do not suffer from light piping. From 12 May 2023, Ektachrome is also being shipped with light leak free labels.
Note that Double-X labels still suffer from this issue.
