All I can say is WOW. I saw this product years ago and because you had to pay for it I didn’t bother looking any further. But I bit the bullet last night and bought it.
It is a gift from heaven!!!!!!!! The difference is remarkable, and striking. I have included some images of Comet McNaught I took. the ambient air temp was 40 degrees Celsius after sunset which dropped to about 35 when we left the mountain top. That meant any camera up there was going to suffer badly with severe noise, and especially at higher ISO's. The shots were tarnished by barrow loads of noise and consequently were shelved in the too hard basket. Not any more. I will be reprocessing these little snippets of history to get some decent images from them, unfortunately I took them in jpeg only (new to the imaging scene I forgot to use RAW).
the image on the left is an original file while the one on the right is the noise ninja processed one
