it's easy to rewrite that module to automatically detect your wb coeffs. but that's not the whole story, noise variances will depend on more than just that. i'm writing a new module to include all of that (because it seems hard to make it backward compatible). > 3.

If lens == 'foo': ca_filter = True. an auto-applying preset restricted to your bad lens doesn't work? j. > I'm sure that there are many more examples of this kind of idea. > > What do you think? > > > > > > > 1: > http://www.pekkapotka.com/journal/2011/12/20/expose-to-the-right-ettr-with-e-p3.html > > ------------------------------------------------------------------------------ > Monitor your physical, virtual and cloud infrastructure from a single > web console.
