Okay, prosumer cameras and digital SLR's, the newer models have intelligent ISO, and let me give you some background, ISO. ISO means International Standards Organizations, and when companies manufactured film they set it up for a different number. Generally, one hundred to two hundred were the low ISO speeds of film. Those had really good grain structure, which means the grain was really fine but here shooting in low light areas like at night or inside of a house you would probably need ISO film of four hundred or eight hundred which is a little bit grainier, and then they had film up to thirty-two hundred for extreme low lighting situations. But with digital cameras they don't really have an ISO characteristic that much with a film but they do have digital noise. So when you raise the ISO level up to thirty-two hundred you're getting more noise in there and it comes across, as purple, purple-izing the pixels. So this has an intelligent ISO that will change the actual ISO of the camera speed of the digital film so to speak. And it's got an ISO sensitivity that you can set up under sensitivity and you can change it to your standard film variations, which are one hundred, two hundred, four hundred, eight hundred, twelve-fifty, sixteen hundred. So that you can, you know, know what you're going to expect but be able to get the lower light situations.
