The syntax was fine. It produced a result, but only as a single band .tif image. No errors. What I would like is a output that is 4 bands, not single band. Also would like 16 bit unsigned integer output, not 8 bit unsigned integer. Did not use Python syntax. And yes, the Help does not mention multibands. I thought that a Con statement would be the best way to approach this, but if it's limited I don't want to be barking up the wrong tree. Before I head down the scripting route, I wanted to check to see if anyone else had used the Con statement for something similar, with similar raster data. BTW, this is for hundreds of multiband rasters and was thinking of running a Raster Calculator batch.
