Pentax Monochrome

Thanks, no rush. Just curious. I was thinking DXO DeepPrime but see it doesn't support the monochrome (can probably be tricked with EXIF though) and I have a couple of others I'd try it with. I suspect those should clean up really nicely.

I think (this is just me theorizing) that monochrome sensors would require some special programming for these modern, AI-based (or at least AI is the buzzword used) noise reduction features. A lot of the noise off a Bayer sensor is chroma noise, and there's no chroma noise on monochrome sensors. I suppose ay NR system that people can run film photos through could also work with the Pentax.

I really like DeepPRIME output for my K-1, it matches that FF sensor extremely well.
 
Maybe, but in some NR systems you can adjust chroma and luma NR independently which should work fine for a monochrome file. Just curious to see how they do really.

Monochrome cameras (and a few others like Fuji X-Tran) use Linear DNG files. The headers are different. I've found several "try-Me" type software packages do not handle linear DNG. The file format is trivial, just not implemented by many packages.
 
Sigma Quattros use Linear DNG too. I have a number of programs that can handle it.

I found a review site that had test photos taken with a K3 Mark III Monochrome and the same shot taken on a K3 Mark III. Interesting to compare them side by side. Unfortunately nothing really high ISO.
 
Couple of shots using the high-contrast JPEG mode and a notch toward the blue tint. It's a strong effect, which I probably won't use much, but occasionally interesting.
