Well, I am not implying to change it. I guess the command is named Log because
in Java Math.log is the function that returns the natural logarithm (ln). See:
https://docs.oracle.com/javase/7/docs/api/java/lang/Math.html#log(double)

Note that there is a log10 function too, but there is no function ln. So
whichever way one looks at this, it could eventually end up being confusing to
somebody.

Jim's comment I think applies to rescaled results in 8, 16 and 24bit images,
but not to 32bit images.
Cheers

Gabriel
