These photos were shot on Kodak SO-554 200 film — a film I know almost nothing about. I came across this mysterious film one day while shopping online and quickly bought 3 rolls. All I can tell you is that the SO stands for ‘special order’ and the 554 is the order number. Kodak SO-554 was packaged in 8-exposure rolls, presumably for testing the emulsion, and came in a box of 5. I have the boxYou can see a photo of the box on BuyMoreFilm.com’s original sales listing. and the expiry date listed on the back is February 2005. A reading of the DX barcode along the bottom edge of the negative points to this most likely being Kodak Professional Color Negative 200, whatever that is. Other than that, there are photos using this film that another photographer has posted,You can view La Fille Renne’s Kodak SO-554 photos here. but she doesn’t know anything about this film either. It’s a complete mystery.
