I think I know what the problem may be. DPP sets Default Noise Reduction according to the High ISO NR set in your camera. In fact, even if HINR is disabled in the camera it sets Luminance NR to 2 - it's not clear whether this is a bug or intentional; a week ago after installing 3.6 I thought it had been fixed but I was mistaken. However, even though the NR is set and will be done during a conversion, it is not done to the display image unless you click the Apply button on the NR tab. (in fact it is not done to the display at all unless you have High Quality Display selected in Preferences.) NR causes softening, but you won't see the effect unless you click Apply, so the jpg is softened but the preview isn't.
WOW! I can’t try this right now (at work), but it sounds like your answer is backed by A LOT of experienceJ
So to confirm, I’ll probably end up re-phrasing what you said, but I want to get it right, as I won’t have a chance to test the results until maybe 12 hours from now..
(1) Noise Reduction softens the image
(2) I don’t remember manipulating this value in DPP, so it’s probably set to default value, which you say will soften my image
(3) But I won’t see it in the preview of RAW file
(4) However NR will be applied when I convert to JPG, and this will cause the JPG to be softer than RAW preview
Should I set Luminance NR to 0? The images were broad daylight, shot at ISO 400, so I guess no Noise Reduction is needed (probably up to ISO 800 on my 50D, I would guess none is needed)?
Just go to Edit Image window -> Tools, third tab (if I remember correct) and set Luminance NR to 0, then probably save this as recipe and batch apply to any images I have coming out of my camera?
