Hello,
Recently I bought K-x as my first DSLR. I am just starting to play with RAW files. As the first step, I shot few images with RAW+ mode, then I tried to convert RAWs to JPGs with Pentax Digital Camera Utility 4.11. and compare results with JPGs from camera.
For low ISO images the JPGs from DCU looks slightly better for me, even without adjusting any setting - and of course the difference grows when I need to adjust something.
But with high ISO the result is disappointing - and the reason is noise reduction.
Please look at following examples.
Here is 100% crop from ISO 1600 JPG from camera. Noise reduction was set to Medium (factory default):
And here is the same crop from image converted from RAW in DCU. The noise reduction options were left default:
Random noise reduction 20
Spurious color signal reduction 150
I also did not change any other setting.
As you can see, resulting JPG has actually lower noise, but the artifacts generated make it look much worse then the previous one.
I tried to play with these 2 settings, but I couldn't even get close to the picture from the camera.
Could anybody please give me some hint, how to make DCU generate the same noise output as K-x itself ?
Best Regards,
Piotr
