[OVNI-SCIENCES] Film d'ovni ?

Hello,

voici le site sur lequel a été posté la video
d'imitation :

Et l'explication donc :

"Actually, when I first saw the ufotheatre video, I
didn't think of any fancy computer graphics or
animations. Though I worked (and partly still do work)
in the TV business for more than 10 years and would
have access to high-end stuff, I figured it would take
ages, even for very skilled people, to produce such a
video by means of a computer, 3D software or anything
like that. The camera movement is just too jerky, and
almost every single frame would have to be fixed
manually, let alone the rather complicated matter of
motion blur etc.

I had the impression it was done, or could have been
done, by means as old as cinematography itself: A
simple glass plane at something around 45 degrees in
front of the camera. This has been done 100 years ago,
and obviously, it still works pretty well. And it
saves a ton of time, the videos took me less than an
hour, no post production was needed (except for the
idiot titles). These videos are right from my amateur
digital camera, no image editing done. The orbs are
nothing but a primitve Flash animation running full
screen on an old 19 inch screen, I think you can even
hear me hitting the space button to start the
playback.

This, and an amateur-like setting of the camera's
white-balance, focus, stupid use of the zoom, lowering
the camera before actually turning it off etc. produce
a way more "real" feeling than most sophisticated
computer animations could do. I couldn't even find a
simple glass plate, so I used an opened plastic CD
case as a transparent medium to film through.

The only real problem is focus, since the mirrored
image of the orbs is very close compared to trees and
the sky. This can be solved, in part, by using a
bigger glass plane of good quality at larger distance
to the lens, which also does not produce two mirror
images of the orbs running on a screen left or right
of the camera.

And that's when I spotted something quite remarkably
in the original ufotheatre video: The zoom and focus
issue. Look again at the ufotheatre clip. First, the
"mother" orb, is pretty much in focus, because the
field of view is very wide, thus eliminating the focus
problem. That's normal photographic physics, in a wide
shot close and distant objects are more likely to be
in focus than in a tele shot. But when they zoom
closer, the "mom" orb gets blurry, exactly what I
experienced while trying to produce the fakes.



All this is no proof that the ufotheatre thingy was
faked, or was faked in the same why I did it, but the
zoom issue makes me think that it could have been done
exactly that way. There's other possible explanations,
but Occam's razor would go for this one, I guess."
