In the mid-2000s, Kodak introduced PlusDigital film (alongside some other lines) in Asia, where digital had not yet fully supplanted film as the standard in photography. PlusDigital, an ASA 400 film, was only ever was sold in America in disposable cameras, but via the internet an intrepid eBayer can import some expired rolls from Asian sellers. It's not clear if PlusDigital is actually it's own unique film stock, or just a re-branded label from a pre-existing film stock, but I think the latter is more likely. (My guess based on this single roll's results is re-branded Royal Gold.) The PlusDigital brand, after all, was not just selling the film, but also the development and scanning service as part of the roll.
In any case, I loaded some up in my Leica M3 and, on a hot and overcast day in June, shot a roll at EI 100 on the streets of San Jose. Below are the results.
