Camera ISO
ISO is a setting on cameras that will allow you to get blur-free shots in low-light situations. The tradeoff is an added layer of noise, or graininess, to your photos.
In order to sell consumers on their cameras' improved low light performance, some companies inflate their ISO rating to make you believe there's less noise at higher settings. Like that image quality at ISO 3200? It's might just be ISO 1600.
