Is anyone here a long-term or experienced user of Piccure+ image sharpening software. I started a free, 30-day trial yesterday and I'm pretty impressed already. I'm using it as an add-on to DxO Optics Pro. It's can also operate as a stand-alone or plug-in with Lightroom or Photoshop. I've only messed with it on less than a handful of images, but I'm noticing very significant sharpness improvements, without artifacts. On my fast computer, it processes fast.

Here's the very first image that I tried. It was taken in low light, at high ISO and low shutter speed (I'd been shooting perched owls) and at a relatively long distance:

I tried it on a couple of other images, including one that I thought was pretty sharp already and it noticeably improved. I'm using low settings so far and haven't seen any hint of artifacts.

I was wondering if any experienced users had any advice or links to helpful guides, etc. I think that it's well worth spending a little time to mess around with the free trial.
