At this setting, my exposure is 1.5 to 2 stops over metered to compensate for bellows extension. If one is to err on exposure, err on the side of slight overexposure - 1/2 to 2/3 stop for some punch to the finished image.

I'm not sure there's one strong enough to hold y'r camera, but have you tried using a focusing rail? I ask because I find one useful when I need to maintain a fixed magnification. Beats picking up the tripod and moving it a tiny distance fore or aft.

I take it you're shooting negative film.

Interesting judging rule. I think I'd share y'r frustration with it.

Cheers,
