Does anyone have any experience with Topaz DeNoise? I see they just released DeNoise 4 and was thinking maybe to pick it up. Are there other noise reduction plug-ins that are better? While on the question of plug-ins, I recall reading somewhere about a plug-in for black and white conversion that's supposed to be great. It allows you to choose which type of film you want your photos to look like when converting them to b & w. Does anyone use this? Thanks.
