We’ve just released a free major upgrade to our noise reduction plug-in Topaz DeNoise. It incorporates a new technology we’ve developed called “IntelliNoise” that primarily focuses on naturally removing noise while recovering detail. (You can read the full press release on DPReview .)

As with previous versions, DeNoise 4 especially shines with photos that have a lot of noise. Think ISO1600 and up, maybe ISO800, with a dSLR. Our claim is that it can make ISO1600 look like ISO100, which I know is pretty hard to believe, but I urge you to try it out for yourself. With the right settings, DeNoise 4’s new technology really can make very noisy photos shine.

I’m personally really happy about this new update. Don’t get me wrong, the older DeNoise 3 was great – it really preserved a lot of detail while removing noise. The only point of improvement that we saw (aside from speed) was the presence of “wormy” artifacts in really heavy noise, and some “flattening” issues. This sometimes had the effect of making the photo look unnatural, even when all the noise was removed. Now, though, DeNoise 4 has the advantage of being able to greatly remove noise, recover detail, and keep the image looking natural at the same time. Quite a lot to juggle, but I think if you try it out on your own photos you’ll really like what you see.

Much thanks go to our beta testers and the Topaz Flickr group for their invaluable suggestions and testing. You’ve helped make DeNoise 4 a possibility.

DeNoise 4 is a major upgrade, but is also a free one for previous owners of DeNoise or the Photoshop Bundle. To access the upgrade, simply download the new version and install it with your existing license key.
