Is there a way to divide all the grey levels in an image by a constant
(not necessarily integer) value? I'm using CS2.

Thanks.

put the image over a black background, and adjust the transparency. You
may want to convert to gamma 1.0 during the divide operation.

The gimp is free, and supports an actual layer divide mode.
