DXO noise reduction

This will be also be posted to the Pureraw thread at the Image Processing forum.

I had heard many positive things about DXO's noise reduction, so I found that I wanted to try it. The results speak for themselves, but let me say right away: this is amazing.

The noise reduction is available in two varieties, as part of their RAW/image processing software, Photolab and as part of their Photoshop plugin, Pureraw. I used Photolab for this. Here's the testing procedure:

Image taken at at 05:29 hrs., 20 minutes before sunrise with a Panasonic G85 using a Zuiko 12-40mm f/2.8 @ 14mm, f/2.8 and ISO 6400. The only processing added is noise reduction, no sharpening.

The whole image processed to jpeg with DXO Photolab:

100% crop, opened with Adobe ACR without noise reduction:

DXO has always been a great RAW converter and has long had arguably the best noise removal algorithms. Additionally I found that they had the absolute best lens corrections in the past too.

+1 for DxO PhotoLab 4's Deep Prime noise reduction.

It helps any supported camera but is especially helpful with m43 sensors (SNR).
