this is my first time using QGIS and I am trying to use it to generate NDVI maps captured from my UAV. However when I apply the NDVI formula in the raster calculator using my NIRGB image the resulting layer has all NaNs. Similarly, when I used the raster calculator again to just save band1 to the new layer, it still gives me NaN. Is this a bug?
