I have a raster greyscale basemap that I need to load into ArcMap. Every time I load it in, the it uses the colour ramp. However I want the original colours to display. As in those that appear, where I to load it into a photo editing program or simply just view it in Windows image viewer.
Does anyone know how I achieve this as ArcMap 10.5 keeps changing the colours to solely black and white and not greyscale as it originally appears.
