    Noise in ACR, No Noise in PS CS3

      I opened some old JPEGs taken with a Kodak DX6490. In one file in particular I saw quite a bit of noise on a white wall. I've been seeing a lot of noise in other old files. I found a copy of the file in question which I had worked on with PS7 and saved as a PSD. opened it up in PS CS3 and lo and behold, no noise ! Opened it in ACR and it's very noisy. Transferred it from ACR to PS CS3 and the noise is still there. What's going on ? Why do ACR and PS CS3 show me noise where it didn't exist before. I never used noise filtering with PS7, so that doesn't come into play. I'm stumped.

          Can you please post the JPEGs here?

          (If you don't have any other place to post, try sending the files to yourself using www.yousendit.com and posting the resulting link here.)

            Here are four versions of the file. Two JPEGS as they came off the camera, and a PSD and a JPEG processed by PS7. I sede a nice white wall when opened directly in CS3, a noisy one in ACR and after transfer to CS3. The images look better (to me on my monitor at least) when I view them with PS7. Looking forward to your comments. Thanks !

              Hmmm... now you see it, now you don't. This time I tried opening the files directly in CS3, opening as RAW from CS3, and opening as RAW from Bridge. This time I do not see the extensive color noise in the white wall right next to the portraits of our fearless leaders (a political statement perhaps ?) ;-)

              There was a reboot of my machine in between sessions. Otherwise, here's my basic config.

              Windows Vista 32 (Home Premium - don't laugh)
              HP Media Center m8200n
              HP w2207 monitor
              NVidia GeForce 6150SE nForce 430
              3 GB RAM
              AMD x64 Dual Core

              Not that any of the above means anything, but at least you won't have to ask. :-)
