Hi Martin & Terry!
Thanks for your responses, and yes, the new feature sound very promising
and, as I understand it more general.
My use case would for example be a farmers field of, say wheat and trying
to take a photo of the first row of straws, with a narrow depth of focus,
uniform natural light - but with exactly the same color in the whole scene
(except sky) it makes it hard to separate out the first row of straws. In
this (and similar situations - crowds of people) it would be useful to be
able to either darken och brighten the out-of-focus areas I think.
Best Regards
Peter
