Another thing to try is developing it with something like Pyrocat-HD and
doing a semi-stand type development. It'll help keep the lights and
highlights from blowing out, while enabling you to get some details in the
more moderate shadows. But my experience (45+ years) is that the speed of
the film is what it is; deviating from that is always a compromise of
something. And, unless you've done it before and know how those changes are
quantitatively and qualitatively going to effect your image, you're pretty
much into just guessing.
