Using a Lumix S5, I have taken photos of the night sky with long exposures (15 sec) and high ISO (3200). I expected some hot pixels; I got many, mostly red in colour. I attempted to remove these with the noise reduction single pixel slider, however regardless of the value of the slider i set, the hot pixels remained.
However, when I used the viewing area slider to zoom in on the image, the hot pixels disappeared, even if the single pixel slider was set to a zero value. I needed to zoom in to at lease 70% for the hot pixels to disappear. Can anyone explain this phenomenon? (This is on a MacBook Pro 16 inch screen.)
The support text about noise reduction states that the single pixel slider is designed to remove white hot pixels. Is there any way to remove red hot pixels in Capture One other than but cloning or healing individual pixels?
