Hi, I tried real quick to get close to what LT does. So far no luck. It seems, however, that for LT you used a different image than for all the other software. It also not the one for which you provided the nef (check her right arm). Is this on purpose?
Any ideas on how to get close to LT's noise correction would be great.
