in fact when ACR detects a high iso raw, it applies automatic and impossible to disable noise reduction. In order to avoid this noise reduction system, I had to go through a hex editor, and change the 3200 iso value to 100 and then opened the file in acr, which detect the raw picture as a low iso one.
Really? Interesting.
Take your uncorrected RAW file, open it in ACR and slide the luminance and color noise reduction tabs all the way down to 0. Save the output as TIFF.
Compare that to your corrected shots (also in TIFF). Is there any difference.
