With digital capture, minimizing noise and maximizing dynamic range can mean making an “incorrect” exposure— typically one that is high key, apparently washed out. But so long as this exposure does not blow-out (turn to pure white) any of the R/G/B color channels, the resulting image will exhibit superior noise characteristics along with the maximum dynamic range.
The constraint is that for ETTR to work well, one must shoot RAW (not JPEG).
ETTR is your ticket to getting the highest image quality possible, especially important for small-sensor cameras, such as Micro Four Thirds. And even with large sensor cameras (full-frame DSLR and medium format), ETTR is a technique well worth mastering.
