I've recently started dabbling with nighttime photography - 30-second exposures at high ISO, for now, since my camera can't do more than 30 seconds without a remote switch. (Don't worry, I've ordered one.) Anyway, at ISO 1600, I wind up with a lot of chromatic noise, especially if I do color correction. Bad!

Fortunately, a fellow photographer recommended Imagenomic's Noiseware. It's available in standard and pro levels as a Photoshop plugin for Mac OS X, and as a plugin or a standalone application for Windows. I grabbed the Noiseware Standard plugin for Photoshop and was rather happy with the results. To my eye, the night sky still has patches that look faintly more magenta than other patches, but I'm being incredibly nit-picky to even point that out. Overall, the before-and-after difference in visible noise is, to use the worst possible cliché, "night and day." This image is just a tiny crop from one of my night shots.

Ok, I just have to say very nice. I asked you about this a while ago since the digital camera I got for Xmas tends to underexpose and make images noisy, but what I really care about is scanned film which in some cases is really noisy.

Just now I downloaded it and started playing with the plugin -- first I threw it a scan of an old sunset slide which looks nice in a slide projector but terribly noisy in the scan. I've fought that scan for hours in Photoshop and never been happy with the results. In default mode, Noiseware made it just about as perfect as I could ever ask for.

Round two was a landscape at sunset, again a noisy slide with crazy colors and all kinds of detail (clouds, trees, grass, elk, etc.). On default it made the grass and elk look like cartoons, but in landscape mode with a few tweaks, once again I was happy. No, actually amazingly impressed.

Number three was a pictograph slide, and I had to fight it a bit here to keep it from making the sandstone look like clay (the film grain and sandstone grain are a little too close in scale) and I'm ultra-picky about detail in these. But eventually I was happy.

Number four was a torture test, another pictograph but on 200 ISO print film (ugh) that had been lost for a while before it was developed (ugh). After being zoomed in and playing with the settings for a bit, I zoomed out and saw an entire figure (a curly tailed dog) I had not even noticed in the original . . . so now I'm going to go buy it! And then maybe I'll even try it on some of the noisy images from that digital camera. Thanks.
