Two full size images - first is the DXO with the second being the Pentax DNG directly from LR. They tended to be a bit brighter overall, even after LR processing Color Rendering - I found the colors to be ever so slightly different. The utility does not let you manually select the lens used - it reads the EXIF meta data and goes off from there, so if you are using a M42, K, M, A type lens - it just selects something for you based on your focal length. I had several images that would not convert, resulting in small 14MB black/blank images - bug report made. Processing can be a bit long - 45 to 120 seconds for each image - based on a 6 core i7, 32 GB ram, 1TB SSD and a Nvidia GTX 2060 with 6GB graphics ram. Also, I read somewhere that it uses just the standard Adobe RGB and no expanded gamut. 
Files Sizes are doubled from about 42MB to 93MB for the K1. This suits me just fine.ĭownsides of the utility. Stars - I see absolutely no difference between the Pentax DNG files, Adobe LR processing and the DXO processing. Also, the color rendering tends to be ever so slightly different. You can back off a lot of this, the images tend to be about 1/3 of a stop darker, contrast tends to be pushed up a bit more, and shadows tend to be much darker, and the image tends to be a bit brighter. This did remove that, however it also tends to be a bit aggressive. With low light or no light imagery, you tend to get a lot of graininess - as in having the images printed on sand. Inherent Noise - Again, overall it did quite well. 
Shooting 2 to 4 minute foreground images - turns in to 4 to 8 minutes instantly - which just makes for a long night. I've been shooting LENR to get rid of them, so this just returned half my life to me.
There were a couple left (as in 2 or 3) in the images I tested - but it took care of the other several thousand quite well. White Dots - It cleaned them up perfectly.1) Remove the White Dots from the K1 foreground frames and 2) Handle the ever inherent noise from shooting in the middle of the night. I was looking to it, to perform a couple of tasks for me, on my low light (actually no light) Milky Way landscape images.
