I don’t understand high pass filter in new GIMP 2.10.10.
Here is the example picture where I would like to use high pass filter:
If I use built-in high pass filters, the original image will only be covered with grey haze:
If I increase the contrast, the haze simply becomes more transparent…:
…until some strange artefacts emerge:
Actually I expect result like this (done with high pass filter script):
Does anyone have any idea what’s going on or what I’m doing wrong?
I am using GIMP 2.10.10. AppImage from @Carmelo_DrRaw in Kubuntu 18.04.
