Noise reduction test
Digital noise is hard to delete as it is really impossible to determine if a "dot" is noise or detail. A good denoising algorithm should preserve all edges and strong details getting rid of most of the noise (especially the colorfull one).
What we are looking at?
The default view shows the image without any post processing (no denoising, sharpening or other tools applied). Please notice that it shows how the noise is rendered by default demosaicing algorithm of the application. White balance was manually set using the grey card. 25% settings of denoising mean 25% of luminance denoising and 50% power of chroma denoising. 100% settings mean that both - luminance and chromance - were set to 100% power.
