Originally posted by tax Hello, There are four denoise filters in Darktable (Linux analog of Lightroom) - (1) non-local means, (2) bilateral, (3) profiled and (4) raw.

Is it possible to achieve the same results that are produced by the accelerator unit in K-1 II at higher ISO's using just mentioned denoise filters on pictures produced with a plain K-1 model?
I'm pretty confident you could achieve at least the same quality of noise reduction as (and possibly better than) the K-1II using a K-1 and Darktable.
In addition to the denoise modules you mentioned, there's another - "Equalizer" - which is, in my view, the most versatile and powerful way of addressing both colour and luminance noise. However, it has limits so far as colour noise reduction is concerned, so I tend to use it in conjunction with the bilateral denoise.
For images with relatively low levels of colour and luminance noise, I have one instance of Equalizer dealing with colour noise (blended uniformly for colour) and a second instance dealing with luminance noise (blended uniformly for luminance). For high ISO images, I add one instance of bilateral denoise set to maximum radius of 30 and relatively low levels of noise reduction (generally between 0.050 and 0.150) for each of the channels, blended uniformly for colour.
The benefit of the K-1II is that you're getting noise reduction tailored to each ISO level straight out of the camera. With the K-1, you'd need to apply different levels of noise reduction in Darktable depending on the ISO setting used.
