**subbed** excellent review smick, i think i'm off to buy this program cheers.

A bit tricky to show you an A3 print from such a distance. This is actually fairly well known that it does this. Its still the best noise reduction there is, but I just wanted to make the point that its far from perfect. How much you see it in any given image depends on the resolutions you're working with but one things obvious , all the reviews I've seen never ever zoom right in on detail, like yourself, and there's a reason for this. It lumps pixels together into homogeneous rows that reduce the resolution and give a slightly crunchy look, staircasing as some call it. It really hates it if there's a hint of moire as well.

It leaves a lot of zippering artefacts on fine feather detail. So its best used sparingly. Large prints can show this zippering.
