If you set that to 0 you'll get a flat image at the expense of one more 
filter in the pipeline.  However, what you want to do is really not 
clear to me.  If you have only one flat image to show then why do you 
need the second array at all??  Can't you just view the other_img.png??

Yes, that will not work.  The LUT just generates colors from scalars.
