Many times i didn't tried ,because as usual,
windows was not very clean, but i thought that
as we are very close to it, near touching it with lens, the focus zone would be after,
i made it in aperture priority mode at f 16 to have great DOF,
iso 1250 to have great speed( flying at 876 km/h):
(iso 1250 1/1250 f 16),
and just used levels and a little bit sharpening in Photoshop,
the result is pretty good, i think ,
so next time you take a plane and you're near window, you will try
