For RGB imagery, this typically is either 0 or 255, unless you are using an alpha band. You can though remove the NoDATA tag from the raster. I know of two of ways to do this. 1. Use gdal_edit with the -unsetnodata, which will modify the existing dataset. 2. Use gdal_translate to copy the raster but by using the -a_nodata and setting it to none, to remove the NoDATA tag I would suggest if using the first one, that you make a backup of the raster, just in case. I hope that helps!

These appear to bands with zero values in two of the three bands. Anyone have a work around or suggest how this can be avoided. I am using the gdal pansharpen tool and latest release QGIS 3.34.
