KP Pixel Shift Images

**tduell** · 02-15-2022, 07:52 PM

The dcrawps output doesn't say it is loading PS images, but does find 4 files, which suggests that the DNG is a PS container file, so a bit of confusion there.
If you use the command line as per my post, above i.e. dcrawps -v -w -6 -T XXXX.DNG, without any changes, what is the output? Please post post the full output to the console here so I can see.
I'm not sure about the green dots, that maybe an artifact due to a error in the program, not sure.
I have tested a linux build of dcrawps with motion corrected and non-motion corrected KP PS files, without any issues, so had concluded it was working OK.
If there are any Windows users of dcrawps that can chime in here with their experiences with the Windows build it would be helpful.

Cheers,
Terry

Well I'm not sure if I should take another photograph possibly and I'm taking two one with motion correction on and one with motion correction off. Which one would you prefer to see the output of or does it matter?

ok here is the total output and command I ran. Image had motion correction ON

C:\0>dcrawps64.exe -v -w -6 -T IMGP8675.DNG
Loading Pentax KP image from IMGP8675.DNG ...
Load PS images...
AHD interpolation...
Merge PS images...
PS artifacts: 0
Scaling with darkness 256, saturation 16126, and

The following is the same command with a different image With motion correction OFF

Thanks for posting those outputs.
They confirm that dcrawps is seeing a PS image and doing the required processing.

Both images appear to me to be out of focus.
I assume they were shot from a tripod, so wonder if AF fine adjustment is required for the lens used.
