Sama ClarkVision aiheesta native ISO:ougle kirjoitti:Eivät ole lukeneet saatikka ymmärtäneet, mitä digikameran "ISO" oikeasti on. Ja varsinkaan, mitä se ei ole:
"One can find on the internet discussions about the "Native ISO" for a camera. There is really no such thing. ISO is simply a post sensor gain followed by digitization. ISO settings are needed mainly to compensate for inadequate dynamic range of down stream electronics. One could specify ISO such that downstream electronics digitize the full range of signal up to the full well capacity. Some may say that is the native ISO, but there is no inherent advantage to this ISO, and in many applications is less than ideal. Digitizing the full range, assuming one fills that range with electrons from optimum exposure, maximizes signal-to-noise ratio at high signals (this is the concept of use the lowest ISO on the camera, and "expose to the right." However, this range provides poor digitization of the low end of the signal, and depending on the camera can have side effects like pattern noise. Alternatively, working at higher ISOs digitizes the low end of the signal range better with the sacrifice of losing the high end of the range."
Ei mulla tuohon mitään kommenttia ole, kun ei ole kompetenssia argumentoida asiasta.
