Emergency Doctors Determine that Trump was Struck by a Rifle Bullet

[Charles Collins]

Mills' camera had a "rolling shutter".

    "Rolling shutter is a method of image capture in which a still picture
     (in a still camera) or each frame of a video (in a video camera) is
     captured not by taking a snapshot of the entire scene at a single
     instant in time but rather by scanning across the scene rapidly,
     vertically, horizontally or rotationally. In other words, not all parts
     of the image of the scene are recorded at exactly the same instant.
     (Though, during playback, the entire image of the scene is displayed
     at once, as if it represents a single instant in time.) This produces
     predictable distortions of fast-moving objects or rapid flashes of light."

Rolling-Shutter Distortion

The left half of the streak was recorded earlier than the other half. In the meanwhile, the bullet had moved a small amount.

That explains it. Technically any single point or pixel in the photo is exposed for the specified shutter speed time. However, the time that it takes to expose the overall photo (or even just the length of the bullet streak) is greater than the specified shutter speed time. Since the shutter “roll” apparently moves horizontally when the camera is in landscape orientation, I imagine that if Mills had had the camera turned 90-degrees (portrait orientation) that the shutter roll would have been vertical and a horizontal bullet streak would have been closer to the correct length for that 1/8000 of a second shutter speed setting. Thanks Jerry!

  Trump's Uncle did far more than, "...went to MIT". He also did clandestine work for the U.S. Govt. Immediately after the death of Nikola Tesla, Uncle Trump was tabbed to independently sift through the numerous "locked down"  labs that Tesla had established across the USA.

Going back to one of the original themes of this posts, emergency room doctors do not act like Sherlock Holmes. They get reports of victims of gunshots wounds coming in, they don't go sit in a corner and smoke a couple of pipes and figure out the details, dydywhile the patients bleed out. They get busy and treat the wounds.

In the Trump case, they don't make a careful study of whether a wound was caused by a rifle bullet or a fragment. They just treat it and report it as a bullet wound.

If the JFK case, they don't make a careful study. Wounds typically occur in pairs. And entrance wound and an exit wound. If they find one wound, they don't carefully look for the other wound and then consider which is the entrance wound and which is the exit wound. If they find a round wound on a dying patient, they will just consider it to be an entrance wound, and not consider the possibility that it was an exit wound that was shored up by a collar.

The statements by emergency room doctos are not Holy Writ.

You began this thread by claiming that Trump was not struck by a bullet or bullet fragment.  Instead you claimed he was struck by some other mystery object three feet long.  Tin foil hat stuff.  Now you appear to accept that Trump was struck by a bullet or at least a fragment of a bullet.   Either way that means he was shot.  Why go through this tortured exercise?  Here is your reason:  "Trump is claiming he was struck by a bullet to make himself seem more heroic, a man spared by a miracle of God."  You want to denigrate this conclusion (a fact) because you hate Trump.  It is very revealing of the psychology of those who pathologically hate Trump.  Ideology is more important than fact.  It is more important to believe something that supports the narrative than your own eyes.

The camera used was a Sony ILCE-1 camera which used a vertical travel mechanical shutter:

But that is not a problem since the camera was turned so that the vertical travel of the shutter curtain was in the same direction as the bullet travel.

While the exposure time is effectively 1/8000th of a second, the time it takes for the shutter opening to travel from top to bottom of the image sensor (shutter speed), appears to be 1/400th or 1/500th of a second (depending on whether it was 35 mm full frame or APS-C).  This means that the space between shutter curtains as it passes over the sensor is 1/20th or 1/16th of the vertical image captured.  So each photo is essentially a series of exposures from top to bottom of 1/8000th second snippets.  The time between the beginning of exposure of the top snippet and the end of exposure of the bottom one would be 1/400th of a second or 1/500th of a second.

If the camera used a shutter speed of 1/400th of a second (2.5 ms) and an exposure time of 1/8000th of a second, the time between one end of the streak and the other would be the width of the streak divided by the frame width x 2.5 ms.  So in this case, I measure the streak to be 21.4% of the total width of the image.  So the total exposure time is:

Exposure time for streak = .214 x 2.5 = .535 milliseconds.

If the camera used a shutter speed of 1/500th of a second (2 ms), the exposure time for the streak would be .214 x 2 = .428 ms.

Bullet speed

If the muzzle speed of the bullet was 3300 feet per second, by the time it travelled 450 feet it would be down to around 2700 fps.  So in 1 ms it would travel 2.7 feet. In .428 ms it would travel 1.16 feet or about 14 inches.  In .535 seconds it would travel about 17 inches.

So it looks to me like that is the real bullet streak is consistent with being captured by a shutter speed of 1/400th or 1/500th of a second with an exposure time of 1/8000th of a second (shutter curtain window of 1/16th or1/20th of the sensor width travelling across the image sensor in the direction of the bullet travel (ie direction of bullet travel in the image).

Well done Andrew. I had the aspect ratio backwards (in my memory). But I did grasp the concept. Thanks for your efforts and correcting my mistake.

I have you and Jerry to thank for the idea. I just worked it out. 

I should add that this also explains why the beginning (left side) of the bullet trail is faint and gets progressively stronger until about 1/4 of the way along.

The beginning of the bullet track captures the bullet as its image passes the trailing shutter curtain.  But that part is then cut off from light as the trailing shutter curtain immediately covers the sensor at that point. After 1/8000th of a second or 1/20th of the full frame width (at shutter speed of 1/400th second), the sensor is fully exposed with the bullet present.  That continues until the bullet passes the leading curtain.  So we should see a faint trail becoming stronger as the bullet moves to the right to about 1/4 of the trail length, then a consistent image afterward until the bullet passes the leading shutter curtain.  That appears to me to be consistent with the image, which adds credibility to the authenticity of the photo.
