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.

TOPAZ DENOISE, THE PERFECT PLUGIN FOR GETTING RID OF NOISE FOR LONG EXPOSURE ARCHITECTURAL PHOTOGRAPHY.

As a black and white photographer specialized in architectural, black and white and long exposure photography, I frequently run into noise issues when taking long exposure photographs. Especially in low light conditions and longer exposures, chances of having noise in your photographs are very likely.

There are several plugins available to get rid of the noise but I’m very picky to what I choose as a tool. Getting rid of the noise is one thing, but retaining all the details, especially in architecture, is another thing. You don’t want to lose all the details, just the noise. And that’s exactly where some plugins are better than others. I need a good balance between reduction of unwanted noise on one hand and retention of details on the other hand. And preferably I need a lot of control so that I can accurately target a specific kind of noise in my image without affecting the rest of the image. For an architectural photographer this balance is essential. I’ve tried many plugins but the last few years I prefer to use Topaz DeNoise as it gives me very good results.

Of course the best thing is to avoid noise, something I succeed in, in the last few years, but it can’t always be avoided. And sometimes I like to add a bit of noise, in especially skies, to get that analog look.

Let’s have a look at a few examples.
