![]() ![]() Both programs retain a great amount of detail and it is very hard (impossible to my eyes) to give one application an edge in this regard. I have written a companion article on how you can fix this in PhotoShopĭetail retention is also very close between the two applications. Topaz DeNoise is slightly more ‘blotchy’ in comparison. In areas of high detail both applications do an equally good job, however PhotoLab 4 is able to produce more pleasing background areas. These images are 100% crops and for a proper comparison should be viewed on a large screen device or zoomed in.īoth DeNoise AI and PhotoLab 4 do a very good job of reducing the noise levels. The second is the Topaz DeNoise AI result, and finally the PhotoLab 4 DeepPrime image. The first is the processed image with zero noise reduction applied. I repeated the test on over a dozen files with varying level of noise – the results were similar on all of the files I tried.įemale wren sitting on a branch with nesting materialīelow are the three comparison images. It was taken on a Nikon D500 taken at ISO6400 in a fairly low-light setting (in the shade) typical of wildlife photography. I then sent the file to DeNoise AI as a TIFF file to perform the noise reduction and sharpening.īelow is one of the test photos I used. I then adjusted the exposure, colour, etc in Lightroom to produce a finished photo.įor the Topaz DeNoise test I opened the same RAW file in Lightroom and applied exactly the same exposure and colour corrections to the file (making sure noise and sharpening was set to zero). dng file with only the optical corrections and noise reduction applied. To test PhotoLab 4 I opened the image as a RAW file and set the best settings for Noise Reduction and Sharpening. To make sure each result is rendered to look the same I have used the following workflow: It is tricky to test the results from two different applications as slight differences in processing (colours, contrast, etc) can change how we perceive the noise in a photo. How much detail was lost in the noise reduction process?.How much noise is left after processing?.There are three considerations to take into account when looking at noise reduction results: How well does the noise reduction work with both programs on high ISO images? Make sure your camera is supported before you buy. PhotoLab 4 DeepPrime only works on raw images. Important: This article assumes you are working on RAW image files. ![]()
