Has anyone seen a multichannel tif file opening as RGB colour by drag and drop (or file->open) but showing the channels if we use bioformat importer? Why does this happen?
an RGB image is a 3 channel image (Red, Green and Blue). I guess this is how Bioformats understands it. I get the same results. You can revert to an RGB representation by [Image > Type > RGB Color] (a 16bit RGB image) or [Image > Type > 8-bit Color] (a 8-bit RGB image).
