 Wide-DR-capable raw processing external software is required (e.g., Adobe Camera Raw / Adobe Photoshop Lightroom, DxO OpticsPro, Capture One, Raw Therapee).When facing higher-DR scenes, metering on most cameras tends to aim for the midtones, often clipping both extreme highlights and shadows of the JPG preview image (seen as spikes at the right and left edge of the JPG histogram, respectively).One might expect that this would automatically lead towards a raw histogram in which the right (highlights) range is neatly occupied as with ETTR.
