[QUOTE="rtchapman, post: 695210, member: 46208"] The difference might be that when you increase ISO in camera, the camera hardware is performing an analog amplification of analog data - pre digital conversion. When you increase exposure in Lightroom you are essentially performing multiplication on quantized numeric data. I would expect that the analog operation is bound to be smoother. I suspect that Northrop is assuming that the same operation occurs in camera or in software. [/QUOTE]
