Probably daft question. How do you downsize the 20mp photo to 10-12mp?


Please understand that downsizing is a technique that can be used to reduce noise in an image.  The act of compressing is likely to cause some certain amount of noise to be averaged out so that it is not noticeable.  The downside is that you have reduced the resolution of the image.

If your image does not have much noise, there is likely no need to downsize.

Or, a product such as Topaz's Denoise AI is superb at removing noise while preserving detail.
