3rd party app support, eh? That's not a real "apple" thing to do!
That's the one thing about Lightroom that I miss. There is some noise reduction included in ACR, but it it's very light duty and isn't meant to compete with NN or anything like that. Still works well, though.
Have you used Lightroom at all, Rich? I'm still curious as to how they stack up. Lightroom is $300.
