Hi,
Probably you are using an older version of PhotoPerfect Express. Please download the latest one ( 1.0 build 82) from our website at:
Arcadia Software -Download
This current build will fix the sharpening discrepency between the final image and the preview when using Perfectly Clear
Btw..you can always activate and adjust the sharperning parameter of Perfectly Clear to your liking by right-clicking its button when this method is selected (see screenshot):
Please note that sharpening is deactivated in the default settings.
Best regards
Hoang-Tran
