I don't know about changing shape but certainly changing shape requires a

approach the horizon has been declared an optical illusion after being
disproven by careful measurement with thodolites.
Ask Vanna for an "E".
The moon appeared MUCH smaller last night during the eclipse itself to
the human eye. Didn't change size in the viewfinder, though.
As good as a theodolite. ;-)
Well there you go. My eyes and brain are subject to optical illusions.
Your E3 is not yet still images an oblate spheroid. As I said: "I don't
know". :-)
The key on this one is the rough serrated edge on the moon. That was
caused by the atmospheric conditions of the various layers of air that
it was rising up through. I've probably got 2000-3000 pictures of sun
and moon rise/sets with this characteristic. Whether it gets squatty
or tall depends on the temperature of the various layers of air. Cold
over warm will give you squatty. Warm over cold will give you tall.
Quite agreed. In fact, for me, it's often the distortion that makes the shot. Not in this case, though. The slightly
imperfect roundness is fine, but the edge effects are too much like pixelization at first glance. I can see that they
are not when I look more carefully, but they detract for me.
And I don't 'get' the rest. I've liked many of your "Slider to the Metal" images, but this one doesn't work for me.
Naturally, the treeline halos offend my picky eye, but that's nothing you didn't already know. Still, this case is
especially blatant. All that bright white coming through the horizon trees, is that something really bright just behind
them - or might it be halo artifacts?
Beyond that, the overly bright foreground pulls the eye away from the moon to the extent that one might wonder why it
bothers to be up there in the sky at all.
In making it bright, it seems to me that the light has become very bad/confusing. The track looks like it is lit by
invisible flood lights. The trees look like there is another moon behind you lighting them up. Sci-Fi multi moon planet?
:-)
This is quick/sloppy, but shows roughly what the horizon/trees would look like without the halo
