Iv’e been trying to get some time to do a proper full review of DXO Photo Lab 4 but I’ve been really busy with client projects and some other things, so I haven’t had the time to fully immerse myself in the software yet. However, I have played around with the new “Deep Prime” noise reduction, and I’m impressed with what I’ve seen so far.

If you haven’t already read about it, the latest version of DXO Photo Lab includes new noise reduction technology that works a little different from how most noise reduction technologies work. It has two key features. Firstly, it occurs as part of the demosaicing process, rather than on-top of it. Secondly, it uses AI to calculate and implement the noise reduction, having been trained on hundreds of thousands of images. According to the company, the result is a much cleaner image with much more detail retained.

I have to admit, I was skeptical at first, but then I tired it on one of my own Images, and I was blown away. In fact, at first I thought I must have made a mistake it was so dramatic.

I used it on a shot from New York at Sunset that I had taken when there last year. I had taken the shot on my Canon G7X Mark 2 which is a compact, 1” sensor camera, that is no low-light king. The shot was ISO 4000.

First, here’s a crop at 1:1 (100%)
