I have an image shot at 3200 ISO and have reduced noise dramatically in camera raw. Satisfied with the results there. However, when opening it into PS CC, the noise is back as if I didn't do anything in ACR. The PS noise reduction filter won't come even close to the results obtained in ACR.
Am I missing something?
Also tried to save it as .tif and even .jpg in ACR but same result when opening those files in PS.
In ACR, have you checked the NR at 100% zoom? If not, it's possible that the noise is still there and whatever algorithm that ACR uses to resample an image for the screen view, is artificially removing noise, that isn't actually gone, and PS is showing that remaining noise.
Alright, thanks. I better understand.
