EXR score
« on: March 08, 2013, 04:01:17 am »
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."

Totally unfair, if you ask me. What is the point of testing an EXR sensor in its normal mode? An EXR sensor is capable of delivering better results in its other modes!

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
