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
This issue was raised initially as a problem with the last beta but on testing I found it also occurs in the new established version of AP. The screenshot shows the use of the overlay paint tool - the brighter area - and the raindrops the result of trying to use the overlay erase tool to modify the extent of that overlay. Since I experiment quite extensively with imagery I use overlays frequently as a valued tool. In this instance the overlay delete brush appears to be painting in an erratic manner and not erasing. This does NOT happen with the overlay gradient tool overlays. You can check on the left of the image that the correct tool is selected. Michael
