 Unfortunately, metering algorithms in different cameras may produce very different results in such conditions.It is not uncommon that when shooting a scene with DR within the sensor DR, the default camera metering results in a raw image with blown highlights and ample empty space at the left side of the histogram.In such case, the ETTR principle of maximizing exposure to the point where the raw histogram is aligned to its right edge, requires a seemingly counterintuitive "negative" exposure compensation.
