Christopher - I've not messed with this too much, but I believe to keep the highlights you should underexpose a certain amount. My D300 is set to adjust EV in 1/3 stop steps. I would try -1/3, then, -2/3, then -1 just to get a feel for things. I think the display would read -.3/-.7/-1 in this instance. This is a case where digital will give you instant feedback if you can run off 3 shots, then view on computer.
Hope I'm not confusing things more. Mark
