DescriptionExisting protocols for evaluating single-image HDR reconstruction methods are unreliable because of large color and tone differences. We demonstrate that the accuracy of metrics can be improved by correcting for camera-response-curve inversion errors. Still, the metrics can detect only substantial differences, and conducting a controlled experiment is preferable.
