I rarely endorse products, but occasionally something remarkable comes along that makes me stop and take notice. At the Recent Daintree Photographic Workshop, Dr Les Walkling was waxing lyrical about the incredible strides that have been made with AI (Artificial Intelligence) and machine learning in image processing. Such a product is Denoise AI from Topaz Studios. This piece of standalone software ostensibly is used to reduce noise in high ISO and/or long exposure images, but it does a lot more. Using Lightroom’s Sharpening and Noise reduction tools as a comparison, I have tested several images to see how the software performs. Each image was well focussed and more or less correctly exposed, some at high ISO and some at lower ISO settings. All images were shot with a Nikon D850 DSLR with the RAW files initially processed in Lightroom. The test images used for comparison in Denoise AI did not have any sharpening or noise reduction applied, the comparison RAW files shown have been adjusted to the Sharpening settings I normally use.
