What struck me is the third object far back, if this is a light reflection of some kind, why is this not illuminated the same way as the rest?
If that makes sense.
If it's a light reflection (which I believe it is), that one would be dimmer because it's a reflection of a reflection. If you look at the full
size image right near that area, there's a even dimmer "object", which would be the reflection of that reflection.
Here's my "interpretation" of it. The sun hits the camera lens and into that magic part of the camera that takes the picture (for the life of me I
don't know what that's called); that much is obvious. Some of that light reflects off the inside of the camera at a given angle and hits the glass
of the lens again. Glass has two
reflective sides (the front and the back), so you get two reflections. Based on the index of refraction, you
get the two reflections slightly apart from each other. These hit that magic part at a slightly different angle than the sun did, so you now have two
These two spots are rather bright, so they're going to do the same thing--you can use your fingers to estimate that the distance between the sun and
the first set of spots is the same as the distance between the first set and the second set. The sun hits the camera at an angle of X degrees; that
light reflects back to the glass at the same angle, back to the camera at the same angle, then back to the glass and back to the camera again at the
same angle. Keeping the angles the same will keep the distances the same--vice versa too, keeping the distances the same means the angle's the
(Note: I'm using the distance between the first spots and the center of the bright thing we're assuming is the sun, not the edge of it.)
If you had super good eyes (and a much more sensitive camera) you'd see quite a few more spots like that I'm sure, all at the same distance from
each other as the first.
That's my take on the situation--index of refraction and angle of reflection, basic high school physics with a touch of geometry thrown in for kicks.
