Terry took this shot and praised the capabilities of Topaz DeNoise:
I was intrigued, so...
I took some shots last night with the ISO set to 'stupid high' (16000, 25600 ) at F5, 1/50th of a second.
The next morning I grabbed the images, processed them from RAW to PNG (my go-to save, I'll explain later). As You might imagine the images were pretty grainy.
Enter Topaz DeNoise.
I processed the grainy images and I was stunned! The quality of the result after running the DeNoise on it, although not ideal, was very acceptable. The only thing that put me off was the level of blurring in some cases. As we all know sometimes you just deal with it because that moment is gone.
Below are some crops of portions of the images before and after:
I said I'd explain my love of PNG over JPG formats. Below is a link to a well presented explanation of the differences:
