[QUOTE="BackdoorArts, post: 360520, member: 9240"] It's the base sensitivity of the sensor in the camera. Most Nikons are 100, Canons have been 200 for a while but some are down to 100. [I][B]Native ISO[/B][/I] is the ISO at which the sensor operates naturally. [I]Every other ISO[/I] is a manipulation of the signal coming from the sensor. Higher ISO levels are amplified, lower levels are attenuated. Think of an audio signal coming from you CD player. If you attenuate it (quieter) you lose some fidelity. If you amplify it (louder) at some point it will begin to distort (noise) more and more the louder you try and make it. At native ISO everything is just as the sensor recorded it with no manipulation. There have to be explanations out on the web somewhere, but I don't have the time to hunt it down for you. [/QUOTE]
