Hi,

Along the lines of the previous post, I have been trying to see what would be possible with CHDK and an evolutionary algorithm, and have concluded that maybe optimal bracketing could be done.

Since the histogram can be measured (and, as far as I have understood, it's one of the few things that can be measured), optimal bracketing would have two (or three, but let's say there are two) shots that would have histograms as far apart as possible, that is, minimal overlap.

In order to optimize it, we could create a population of possible exposure/aperture pairs, which would be evolved to get the optimal one. I don't know if the space is big enough for an exhaustive search, but I'm betting it's not (exposure-wise, for instance).

If this is eventually too slow, another stochastic algorithm, like Simulated Annealing, could be used. What do you think?

Cheers

JJ
