If the photo is to be printed on an inkjet printer, converting to grayscale
could force the printer to print only with the black cartridge.  If one
desires to print BW with both the color and black cartridge (I prefer this
as generating a more subtle grayscale in the print), you can leave the file
in RGB mode and simply select "desaturate" to remove any color bias.
