Very impressed by Affinity Photo, and one of the attractions was the ability to deal with RAW files. I have a Canon Powershot SX30is which does not natively produce RAW files, but with CHDK firmware it will save as DNG. When I import these into Affinity (or view them in Faststone), they have a large amount of noise which seems to to be like the descriptions of stuck pixels. Jpgs created in camera at the same time are clear of noise. I am able to clear the coloured pixels fairly well by setting Luminance and Colours to around 90% in the Noise Reduction panel, but this leaves smaller black pixels - lots of them! I have read up on dead pixels and hot pixels but these shots were around 1/30th of a second. Any ideas would be very welcome! Thanks
