Overall, then, 1.7’s improved demosaicing and noise reduction combine to produce cleaner, more usable imagery. Notice that even the dimmer stars have been retained, meaning you can apply aggressive noise reduction without destroying finer detail. This is clearly a vast improvement for 1.7-as well as reduced colour contamination, the new luminance noise reduction results in less ‘splotchy’ detail around edges, such as where the stars meet the sky. Let’s take a look at the luminance noise reduction:Ī comparison of the noise reduction between 1.6 (left) and 1.7 (right) So far, this has highlighted the improved demosaicing and colour noise reduction. Even if you chose not to use any luminance noise reduction, the noise ‘profile’ you get with 1.7’s RAW development is far more pleasing and usable. This is far less pronounced in the bottom image (1.7).īear in mind these are the initial results when you first open a RAW file: by default, some colour noise reduction is applied, but luminance noise reduction is not. Look closely at the noise profile of the top image (1.6) and you’ll notice distinct rectangular shaping. After noise reduction in 1.7, there is noticeably more detail available to work with.Īpart from the improved handling of colour noise, the biggest improvement for me is the reduction in the bayer pattern noise-this is often referred to as a ‘maze’ pattern. The noise profile actually appears slightly sharper, but this is a welcome change-another complaint regarding 1.6’s development was that images could appear ‘blotchy’ and soft after noise reduction. The bottom image (1.7) has less chrominance noise and reduced colour pollution/patterning. For most well-lit imagery shot at lower ISO values, the quality of the RAW development was more than sufficient-where it fell apart, however, was with more esoteric imagery like astrophotography and long exposure photography.Ī comparison of demosaicing quality between 1.6 and 1.7Īs an initial result, the differences are perhaps quite subtle. Speaking personally, the biggest issue has always been a combination of the demosaicing and subsequent noise reduction-it wasn’t particularly effective with noisier images and would often fail to remove the visible bayer pattern noise. Demosaicing and Noise ReductionĪffinity Photo’s RAW development has always been regarded as a bit of a mixed bag: common complaints were directed towards handling of image noise, especially with low light imagery, as well as a lack of lens correction options. Version 1.7 of Affinity Photo launched back in June, and along with a new host of features it also boasted improvements to existing functionality-one such improvement was related to RAW development, and this can actually be broken down into several key areas. The 1.7 update of Affinity Photo included some lesser-known improvements to RAW development-let’s take a quick look at what’s changed.
