The DX code is the silver and black pattern on almost every film cartridge. 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 point-n-shoots) on which you cannot set the speed.
The solution is these DX-code sticker. Simply stick them at the right spot onto your film canister, and your camera will use the desired ISO settings.
Choice of ISO50, 100, 200, 400, 500, 800 and 1600.
Price is for a single piece of the sticker for one film cartridge.
