Good day Eric,
I assume that your images or stacks are 32bit because otherwise ImageJ
won't display negative values.
For setting the outside to a given value you could invert the selection
(Edit >> Selection >> Make Inverse) and then set the now selected area
to your liking (Process >> Math >> Set...).
You may use the macro recorder (Plugins >> Macros >> Record...) to
record the sequence of actions and use the resulting macro for future
processing.
Regards
Herbie
