I have tried both CS4 and Can*n DPP both have the same problem, another
problem I found at the same time is CS4 failed the color accuracy to a great
extend on the shadow, that is why I always stick with original RAW converter
from camera manufacturer.
I won't consider 1 stop is deep, check the RAW I just posted.
I may try "dark exposure" compensation but this is not a "real" solution.
For such an expensive camera I didn't expect it is so poor!
