I changed the tvscl to tv, and indeed it makes no difference since I
already bytescaled previously. I use the maxes because my maximum
count for each channel is different (red is much more than green and
blue).

I also switched the blue and red to get a real RGB opposed to BGR. The
image does seem to have changed from an RGB to a BGR...an area which
used to be all red is now all blue...however, again clicking on it and
looking at counts at that blue pix for difference channels tells me
that the red frame had more intensity there than the blue frame, yet
the pixel color is blue. I would expect if the red frame to be much
higher intensity the pixel to be a reddish purple...not blue..! still
not understanding how true=1 creates an rgb image..
