I asked Polaroid this question. Can you just increase the exposure a bit
so instead of a density range of 0 to 3.0 you could have 1.0 to 4.0?
The answer was no. They're not set up to do that.

It would seem like something you'd want to do. How many negatives have places
where the density is 0.0? It seems to me that you're just losing some of you're
dynamic range. I guess I've had some _slides_ that had clear places on them.
