This a comment for this page on the website
"To ensure a fair comparison with sensors from other manufacturers however, DxOMark presents Sensor Scores for the Fujifilm XF1 using a normal exposure mode and not EXR Mode."

Why not present both scores - with EXR and without - but use traditional scores in comparisons against others? I think it would be fair for the consumers to know what can be achieved with different approaches.

Hi,

Thanks for your interest in DxOMark.

DxOMark score focuses on the sensor only. In the case of the EXR sensor, both modes available do not change anything on the sensor itself.
If EXR mode is activated, it only underexposes one half of the image. The pixel quality is not impacted. So on a sensor point of view the potential gain in dynamic is compensated by the loss in resolution.
In JPEG, and with a specific algorithm, some potential gain could be observed but we do not evaluate final images here.

Best regards,

The DxOMark team
