The camera operator, presumably, would have to know that.

Technology still has not freed us from the curse of "pilot error."

The whole reason that they keep their focus is because
likes all things air force,

they don't keep their focus,
they're not cameras,
they're not really that smart,
They're standard issue milspec (1 ea),
Pentagon video feeds.

It's don't work any differently
than the local weatherman in
Cape Kennedy does.

If the camera operator can tell a building from a rock, that's
probably all the focus one needs. Hitting the right building
is a plus -- as shown in Bosnia.

Besides, the missile is moving quite fast. Does the operator
have time to pull out a lightmeter and estimate f-stop?

If the operator is a pigeon, maybe ...

Biological guidance and delivery techniques were under development
during WW2:

I saw it from "A Century of Warfare", a documentary, maybe from the
discovery channel. It claimed the video was shot from a camera installed
on the missile.

Zoom would not be usual on a missile. Some of the cleverer ones have
switched fields of view.
Focus adjustment is also generally not implemented, since by the time
focus degrades, some tens of metres off target, all parties are past
caring.
Bombs would not generally have full video imaging systems, rather using
some kind of centroid seeker to stay on target or marker. This is also
true of all but the most sophisticated missiles. Are you sure the video
you saw was shot from the bomb/missile and not from the dispensing
aircraft?

 

When watching the vision, did the target get bigger and closer until
blackout?

Or dis the vision look like it was rotating and you could see the
mushroom cloud of the explosion?

None needed.
Think about it, the camara angle starts narrow stays narrow for 95% of the
flight then goes wide?
does it have to go wide?



But the camera has to stay in focus before it can shoot. In the movie, all
the pictures
in the few frames before blackout are all in focus.

I have a webcam and a disposable cam that both focus from about 4-5 feet
to infinity. IOW, _everything_ beyond 4 or 5 feet is in focus.

Are you expecting to see the picture go out of focus in the last 5 feet of
the missile's flight?

Cheers!
Rich

Some errors are intended.

Verily, then they cannot be errors! That presents paradox!

Sadly, you have made this error over FIVE groups!

Stoner pigeons? I wondered what Bert on Sesame Street was always feeding
"his little friends"?
