The DX code is the silver and black pattern on almost every film cartride. Inside most electronic film cameras, there is a series of metal pins that read the code and tell your camera what your film speed is. But, what if you bulk-roll your film into blank cartridges? What if you want to push or pull the film? What if you're using an experimental film? If you have an SLR, you likely can change the ISO setting manually. However, there are a lot of cameras (especially compacts and point-n-shoots) on which you can not set the speed. After many years of testing various materials and printing methods, the Arista DX Code Labels were born!
Control your ISO with DX Code Labels. No more DIY hacks, no more scratching film cartridges, and no more aluminum foil. These DX code labels will work with any camera with DX code sensors. Now you can use any films that are non-DX coded with your compact and point-and-shoot cameras!
Please note that the code ONLY has ISO info, it does not has info about the number of frames. However, most compact cameras do not read the frame count on the code and most of the ones that do don't stop at 12 frames just because the DX code says so. So, almost all of your DX sensor-equipped cameras should be able to use all of these labels regardless of how long the roll.
