Thanks both, interesting to get real-world feedback.
A lot of my photos to contain fur! The ones I posted above came out very well I think, but a few others I've tried have come out with the artefacts that you mentioned. They almost look "cartoony" or "sketched", but it can be mitigated fairly well by adjusting the level sliders a bit.
The other thing I take a lot of photos of is planes (air shows etc), which is why your original image with the radio controlled plane caught my eye... that was impressive!
I do like the fact that they seem very active with updates and refinements, which gives me a lot more confident about parting with that much money + getting the updates in the future.
I'll dig through my archives and mess about with some aviation photos on the Trial version too, to see what I can come up with. The problem is that I am fairly strict with deleting anything that's even slightly blurry, so not sure what trial subjects I might have!
Thanks again

NP. PAI can do excellent things but also drop the ball. Currently they are 1.1.7. With these weekly updates there will be about 30 more by my renewal time. You figure they would have it worked out by then. Kinda of a pain but I'll stick it out. If PAI fails on a file then I'll use PureRaw.
Maybe just getting Sharpen AI for now will help you with your air shows, however they are not updating like they used to. I'd test it out.



. Even if I tune-down the sharpening, the patch right at the top of the image on the right still looks "dodgy".
