-Increases dynamic range by sampling the sensor at two different ISOs, switching ISO for every other line pair. This trick cleans up shadow noise, resulting in a dynamic range improvement of around 3 stops, at the cost of reduced vertical resolution and increased aliasing and moire.+Increases dynamic range by sampling the sensor at two different ISOs, switching ISO for every other line pair.
