Can you tell me more about the Pro+ version? I'm a little reluctant to spend (I think it's $80?) but if the PS plugin works well, it may very well be worth it!
It's hard to see it fully when your photos are so small, but yes, NeatImage Pro is well worth the price! I don't use it all the time, but when I do, it's fast and flexible. The pro version can be invoked from within Photoshop as well.
Honestly, this comparison doesn't do it justice. Having to size down to show both side by side still shows improvement, but the full-size version of these shows the real power of this software. I'm not affiliated with them in any way, but when I find something as remarkable as this, I do like to share.
