                                       OPINION                                        
               We have carefully considered all of the arguments advanced             
          by appellant and the examiner and agree with the examiner that              
          appellant’s claimed invention would have been obvious to one of             
          ordinary skill in the art at the time of appellant’s invention              
          over the applied prior art.  Accordingly, the aforementioned                
          rejection will be affirmed.                                                 
               Appellant’s claimed invention is a method for sensitizing              
          tabular silver bromoiodide grains or silver bromide grains doped            
          with selenium or iridium by contacting the grains with a
