This page looks at image quality at ISO 100 with 14-bit lossless capture in a strongly backlit situation with the typical camera metering underexposure of nearly a full stop.
To retain highlights, it is often necessary to cut down exposure, which impacts noise in shadow areas. Plus the camera often screws the pooch with its film-age metering sensibilities (almost a full stop of dynamic range wasted here). How well does image quality at ISO 100 far when pushed to bring out shadow detail?
Includes crops and discussion, including how to maximize image quality.
