Today Topaz released version 2.3 of its flagship noise reduction app,
DeNoise AI.
Attached is a screenshot of a detailed crop of one of my old 2003 digital images getting a spa day in the just-before-release beta (shot handheld, from a plane window, though the haze, at extended zoom, with a non-DSLR).
And another of a 2003 night fire (yes, of course, in California).
(I see DeNoise is now discounted as a launch special.)
