Medium Raw Dynamic Range Loss A7RV

Recommended Posts

I was shocked by a highlight recovery test I did with the A7RV raw formats. I can't tell any difference between compressed, lossless and uncompressed. However, when using Lossless Medium, there is a huge loss of dynamic range. I didn't expect this at all. I expected it to stay the same, just sample less pixels. I wonder if this is a bug. I overexposed the sky behind my house by about 3 stops and then tried to recover. The image with the grey sky is the Lossless Medium, all the detail was lost.
