Another way to approach this problem may be to scale the colors and
not the image, especially since you are working with a small dynamic
range.

TVLCT, r, g, b, /Get
rnew = logscl(r) ;These are David Fanning routines as well
bnew = logscl(g)
gnew = logscl(b)
TVLCT, rnew, gnew, bnew
colorbar, minrange = 0, maxrange = 70.7107, format = '(f6.2)', /
vertical, /right

The colors in the colorbar are logarithmic, but the values are linear,
if that makes any sense. I don't like scaling the images because it
can take a long time for the images I work with. I think it's easier
to read too.
