I need to display an RGB raster on QGIS, with Multiband Color render type. After I set the Contrast Enhancement option to No enhancement, this is how the image is displayed.
No issues so far, since it is the correct visualisation. Unfortunately, when I set the transparency to 50% the colours are totally altered, as you can see in the following image.
There is not a transparency band, therefore I have set the Transparency Band option to None. Also trying to assign specific transparency band the result is basically the same.
