Topaz offer a fully functional trial, so now would be a good time to test this program out. The only downside it has is speed – it is not the fastest noise removal tool. I think it’s fair to say that Topaz DeNoise AI has produced an incredible result here. The chroma (colour) noise is really grotty. Insanity! At this setting the images are so noisy that we could expect no program to make them perfect. Gigapixel result Recover real details for actual sharpness Increasing edge contrast is the simplest way to make an image look 'sharp', and how most other upscaling software works Topaz Labs has a new tool and is not a plugin or even a new feature for its Topaz Studio In particular im using Topaz Denoise, AI Sharpen, and AI Gigapixel on a Mac. It is the quality of DeNoise AI’s result that makes them seem substandard. In the past I’d be saying how good DXO and Ninja had done. In each case, Topaz DeNoise AI has removed more noise and produced a clearer, sharper result that the others. In the comparison pictures, Topaz DeNoise AI’s result is on the bottom right of the grid: The noise is there, but it’s not too bad. This is about as high an ISO as I would normally use with this camera. DXO and Ninja are excellent noise removal tools, so this is a good test. This time I used JPEGs from the Canon M50, a APS-C camera that produces far more noise than its full frame big brothers.įor this test, I put the same images through DeNoise AI, DXO Photo Lab 3 and PhotoNinja. And there is so much detail in 16 bit TIF files. Maybe that makes it too easy… Full frame cameras don’t produce that much noise, even at 8 ISO. In my previous test I used 16-bit images from a full frame camera. Unticking any of the images allows you to make adjustments to a subset of the images. In the above example, it applies the settings to all the images in the batch. You then benefit from DeNoise AI’s assessment of the image and can tweak it if you want to. A good trick is to select Auto and then switch back to manual. You can choose between automatic and manual noise removal. The interface is simple, refreshingly so: Topaz DeNoise AI Interface Removing chroma noise has the side effect of reducing colour saturation so it’s good to control the process. This new setting lets you decide the degree of chroma noise removal. Previous versions of DeNoise AI removed chroma noise automatically. Chroma NoiseĬolour noise differs from luminance noise and at very high ISO settings is difficult to remove. Noise characteristics are camera and ISO dependent so noise reduction is an ideal candidate for doing en masse. But noise reduction can – if you have a bunch of images taken in the same light and taken at the same ISO setting then it makes perfect sense to batch process these. Batch processing images doesn’t always make sense.
