I wonder whether the old analog trick of a preflash would work on digital sensors too? This was even implemented in German semi-consumer-range slide-copiers (with Novoflex bellows, customized to accept a tiny pre-flash cone in the side of the bellows (creating a homogenous white image, at very low intensity, just enough to decrease contrast....in 3 adjustable settings) Tricky to fabricate this yourself, even more without a bellows (like a rigid-tube slide-copier).

For pre-flash to be successful there has to be a 'toe' to the response curve, and reciprocity failure for long exposures.
AFAIK, these don't apply to digital so pre-flashing, while raising the base density, would not allow additional information to be captured like on film.
