![]() ![]() By adding grain we can create an illusion of more detail in the image. Grain - after applying aggressive noise reduction images often lack detail and can look cartoonish.Dithering - see denoising style from Aurelien Pierre.It is important to adjust parameter Threshold. Sharpen - to help recover detail lost in denoising process.Lowpass - to reduce chroma noise, see denoising styles from William Ferguson and this video.Hot Pixels - with aggressive parameters can help remove outlier pixels.Demosaic - changing parameters can impact especially chroma noise.Some photographers include other modules as part of their noise reduction procedure too: Using them efficiently can feel a bit daunting: Darktable seems to offer a range of modules suitable for the task. Some applications offer one-size-fits-all solutions to keep user choices (and possible confusion) limited. ![]() Reducing noise in a photograph can be a complex task.
