Multispot metering

[Francois Gobbi]

I was asking myself if ML could add multispot metering capability to its photographic functions. For me multispot is the best way to have the correct exposure control on you shots. I had it on Canon T90, Olympus had it on some OM series cameras, but nowadays I believe only some pro DSLR provide this kind of metering that in itself is nothing complicated: it calculates the median EV value of a sequence of spot measures when you're in spot metering mode.

even tough idea it self is nice, I think ETTR gives better result (when used right)

In some cases^*), ETTR actually uses the median EV value for a very large number of spot measures (all the pixels used to compute the raw histogram).

^*) when midtone SNR limit is enabled and kicks in; the actual exposure will be either the one metered from median (with some highlights clipped to prevent noise), or something brighter (if the exposure can be pushed to the right without clipping important highlights).
