Re: ETTR - The Quantization Levels Meme That Would Not Die
In reply to Detail Man, Mar 21, 2013

Speaking of the relation between ISO and noise:

Somewhat counter-intuitively, for fixed aperture/shutter speed, it is best to use the highest possible ISO (without clipping highlights); this result is consistent with the ETTR philosophy, since using higher ISO pushes the histogram to the right if one thinks about things in terms of raw levels (ADU). However, the benefit from the use of higher ISO comes in the shadows, not in the highlights where "there are more levels"; to demonstrate that will require some more detailed analysis of the noise and S/N graphs on page 2.
