How To: Apply the same symbology to multiple rasters in ArcMap

Right-click the raster name, and click Properties.

Click the Classify button to manually set the number of classes and class ranges. Click OK to close the Classification window, and display the Symbology tab.
Select a new color ramp to emphasize the differences. Click Apply and OK.
Save the raster as a layer file. To save, right-click the raster name in the Table Of Contents, and click Save as Layer File.The new file has a .lyr extension. Note the location of the layer file.
