Filter Name Despeckle
Compatibility Adobe Photoshop 5.0 and later.
Required RGB working-space

Any linear RGB working space.

Description Noise reduction by blurring daptively according to standard deviation of the current kernel area.
Installation Download and copy all files from the zip archive into the /photoshop/plug-ins directory.
Setup

Open a higher bit-depth image (or convert a 8-bit/channel image to the 15-bit mode, then enter to the filter dialog and press Alt+g to open the Define screen settings -dialog.

Enter the system gamma space that is the gamma value from the Adobe Gamma utility (or from other system calibration utility) not the gamma value from the RGB setup.

This one-time-only step is needed in order to have the image in the preview box in the 16-bit/c mode to appear somewhat correctly (the preview-box when the image is in 16-bit/c mode is not color-managed due to the bug in Photoshop).

Selection Dopdown

Quality: Normal (about the same as the Despeckle in Photoshop).
Quality: Better (better than the Despeckle in Photoshop).

Notes: Not horribly fast, but does it even in the 16-bit/c mode.
