If you’ve ever used Topaz DeNoise for high ISO noise reduction you might have noticed a posterized effect occur on certain images. Often this posterization isn’t evident until you increase the auto-brightness, where you then see the unnatural swerving of tone gradation going this way and that.
Baffled by this effect, like a scientist I sought to figure out how to get rid of it, mixing the sliders up every which way until…eureka! To get rid of posterization all you have to do is increase the ‘Add Grain’ slider and bam! Posterization depleted.
Grain added – No posterization

Normally I go to great lengths to capture and present my subject as I saw it. This approach is based on realism when communicating the experience; whether the awe of a beautiful landscape, the intrigue of ancient architecture, or conveying the essence of a person in a portrait.
You’ve probably run into this issue at one point or another – how to sharpen an image with high-iso noise without worsening the noise artifacts.
It’s the epitome of a Catch-22 scenario. By applying noise reduction, you sacrifice detail. But by sharpening the image, worsened noise is a result.
So how does one go about resolving this?
Well, you’ve come to the right place. As first instructed by Gabriel Fontes, this image sharpening technique he invented allows you to effectively sharpen an image, leaving the noise untouched.
Try it out yourself to be amazed.
