It would be possible for you to post any sample images (or crops) from your tests to show the difference?
Thank you in advance.
(I use LR3, RD 1.9 and DxO, just starting with the last one)
this red carpet pic is not really sharp but a typical surrounding for my kind of work: fast pace, tungsten, moving people, and shows the typiscal differences seen in any picture of this kind.
this was taken from a distance with canon 1ds mk3 and 50L, ISO 1000, 1/160 sec, f 6.3
1st comparision: left side is c1.632, right side is raw dev.193
2nd comparision: left side is DXO 7, right side is raw developer 193.
Both not in standard, but developed to my best needs, including noise reduction, sharpening, wb etc.
