I have been using PDCU ever since I got my first Pentax DSLR (K10D) to "develop" my DNG (not PEF) RAW files taken with either my K5 and/or my K7.
After
years of doing this ... (be gentle here), I have realized
today only that once the file has been "saved" as a JPEG image, that there is some obvious waxing effect (looks like smoothing of the details) to the extent that fine details are lost, especially at high ISO (2400 and up).
This is when I pixel peek at 60 to 100 %.
If I take that same RAW file and extract it with Photoshop CS5 ACR, there is no such waxing of the details.
But there is a fair amount of noise which I usually deal with Topaz Denoise (plug-in). That in turn will cause some loss of details but not as much as with RAW to JPEG files with PDCU.
When I looked at the parameters (default) set in PDCU, I see that
the only noise reduction option that is "checked" is something called spurious noise reduction".
The question(s):
1. Should I reset the PDCU option for spurious noise reduction at zero?
2. Is there any way to make sure that the RAW file will not show loss of details once converted to JPEG?
3. Any alternative way suggested?
Thanks for all suggestion(s) and/or comment(s) !
