Hi Ken,

If you are displaying using a ScalarMap to RGB, then you might
try increasing the red, green and blue values in the table via
calls to ColorControl.setTable().
Java3D has a problem with its gamma correction, as reported
to Sun in bug report 4316844, that causes images to be darker
than they should be. It is very noticeable running 'java Test51'
in visad/examples, where the captured image is brighter than
the Java3D image that it was captured from. Hopefully this will
be addressed in the next release of Java3D.
Cheers,
Bill
