I was in Tokyo a couple of months ago, I used a Lumix G8/GH81, but forgot to turn on the AutoNoiseReduction for Long Exposure . Nevertheless, I came across a strange behaviour with DxO’s processing and Noise Reduction. Attached you will find a comparison of a photo (ISO 200, 4s) without any noise reduction at all, on the left is the DxO processed version, on the right is Capture One11. Why is the picture quality out of the box with DxO so bad in this case? Why are single pixels/dead pixels so damn pronounced?
Furthermore, DxO’s Noise Reduction, regardless what version I use (HQ or PRIME) produces white or at least brighter blemishes. It is not that much seen in CO11’s case. In addition, I can’t even remove every “dead pixel” in DxO PhotoLab, even when the slider is set to 100. With Capture One it’s not a problem.
This is all not an issue in daylight images with PRIME. I really don’t understand what is going on here.
Don’t get me wrong: I am a longtime user of DxO and I love the PRIME NR which in my opinion is far superior than that of any other program, but in cases of dark images it’s not usable when it produces results like that.
