So many companies find it hard to develop new formulas for film; so what they usually do is buy a huge bulk rolls of film (usually from Kodak) and repackage/rebrand them as they’re own. Usually the bulk rolls are older formulas that are not longer on the market so Kodak doesn’t mind selling them off.

The “red band” however is a light leak. This happened cause the weather in Japan at the time was colder, so the oils in my film camera kept slightly freezing so the shutter would get stuck at a certain position letting excess light hit the film. This “overexposes” the film creating interesting colors and shapes on the image.

Sorry for the long explanation 😅
