Here are some fresh news:
I have received one more email from the fellow at Capture One, here is the script:
Hi Jacques,
(I had asked if Monday would be OK for a telephone call
Yes. Note, my call is to discuss the missing files.
(Note: IMPORTANT)
Capture One does not support the Pentax version of the DNG file. Capture One can read the DNG file but not the locked Pentax settings so each image is treated like a raw unadjusted file. In any case, files should not be lost. The Capture One process is none destructive and does not change the original file data. That's what I would like to discuss and see if we can find the missing files.
(Note: IMPORTANT again)
Please shoot using the PEF format if using Capture One. Walter
So, I had switched from PEF to DNG quite a while back, assuming that the DNG format was more "universal".
Now I am rather baffled because Capture One will read the PEF's correctly (yes or no? ... not sure about that) vs. the DNG's from the K5.
Anyway, I am not going to re-switch to the PEF format and will continue using the Pentax DCU which reads perfectly the DNG's as well as the PEF files.
I will see what happens to the RAW files that were mysteriously removed from the original folder BUT show in Capture One, albeit very badly tinted with purple and green.
More soon.
Cheers.
