Topaz DeNoise AI

Noise reduction that separates grain from detail using trained models rather than smoothing, recovering usable images from high sensitivity frames that conventional tools turn to mush.

Version 3.7.2 1.34 GB Windows 10 / 11 (64-bit) Updated 6 days ago

Overview

What this release is

Conventional noise reduction works by smoothing, and smoothing cannot tell the difference between sensor noise and fine detail, so it removes both. The result is the familiar waxy look where the noise is gone and so is every eyelash and fabric weave in the frame. This program takes a different route, using models trained on matched pairs of noisy and clean images to work out which parts of the frame are noise and which are detail.

In practice that means a frame shot at a sensitivity you would normally throw away comes back with the grain removed and the texture still present. It is the difference between an unusable file and a printable one, and it is why the program found its way into the workflow of anyone who shoots in poor light.

Four models are included and the automatic mode picks between them. The standard model handles most cases. The low light model deals with the mixed noise and colour blotching that appears on very long exposures and very high sensitivity. The severe noise model goes further for the worst cases at some cost in detail. The raw model works on undemosaiced data, where noise reduction is most effective because it happens before the colour interpolation stage smears the noise around.

Everything is previewed at full resolution with a split view and a comparison grid showing all four models against the original, so the choice is made by looking rather than by guessing. Sharpening and detail recovery sliders sit alongside so the recovered detail can be brought back up without amplifying what was removed.

It runs standalone and as a plugin inside the major photo editors, with batch processing for pushing a whole shoot through the same model. This build is licensed with the trial watermark removed.

Feature set

What you get

Detail preserving models

Trained to separate sensor noise from real texture rather than smoothing both together.

Four models included

Standard, low light, severe noise, and a raw model that works before demosaicing where noise reduction is most effective.

Comparison grid

All four models previewed against the original at full resolution so the choice is made visually.

Detail recovery

Sharpening and recovery controls that bring texture back without amplifying what was removed.

Batch processing

Push an entire shoot through one model with consistent settings and no per file attention.

Plugin and standalone

Works on its own or inside the major photo editors, fitting into an existing workflow.

Changes in this build

What changed

Improved raw model with better handling of colour blotching at very high sensitivity
Faster processing on recent graphics hardware through better memory scheduling
Comparison grid preview generation made considerably quicker on large files
Better preservation of fine repeating patterns such as fabric weave and foliage
Fixed the tile seam that appeared on very large files processed on low memory cards

Installation

How to install it

Extract the archive to a short path.
Run the setup executable as administrator and choose the host applications for the plugin, which must be closed at the time.
Apply the included licensing step before the first launch so no watermark appears.
Open the preferences and confirm the graphics card is selected rather than the processor fallback.
Run one image through the comparison grid before setting up any batch, so you know which model suits your camera.

Questions

Before you start

Which model should I use?

Start with automatic, then check the comparison grid. Most cameras settle on one model for most of your work.

Does it work on raw files?

Yes, and the raw model is the strongest option because it runs before demosaicing, where the noise has not yet been spread across channels.

Can it run without a graphics card?

It falls back to the processor, correctly but far more slowly. A batch will take hours rather than minutes.

Why does the result look over sharpened?

The recovery sliders default to a level suited to heavier noise. Reduce them once the noise itself is handled.
