It wasn't a vapor trail. To get a vapor trail off a bullet you need atmospheric conditions at or very near to what would naturally cause fog. You also need a very fast bullet. The only cartridge I ever shot and perceived a vapor trail was .257 Weatherby Mag and they probably chronoed 3800+.

What you are seeing is called bullet trace. It is the change in refraction of light cause by the pressurized air as it is pushed aside by the bullet. You can not perceive it with your eyes with a bullet moving left to right but you can from directly behind it. It hangs in the air long enough to be caught by a camera going left to right. I have watched it hundreds of times from the bench shooting F-class or standing directly behind someone on the line. You can follow the travel of the bullet to the target or more usefully to "not the target" when you miss paper and there isn't a dust kick.


Just a guy in the pit shooting the correct exposure through a fast lens that wanted (or was OK with) limited depth of field. He was also shooting big/fast bursts which gave him that amazing shot. Nothing about this indicates any sort of conspiracy in and of itself. Just the musings of someone with just enough knowledge to hang himself or possibly full knowledge that just wants to push an agenda, plenty of people responding to the tweet were lapping it up.

Also other guy mentioned maybe faster prime. But I doubt it.


The old news/journalism standard setup was a high end 24-70 f2.8 zoom. Some photographers liked the 17-35 for really close/wide shots though.

The other atndard setup was the 70-200 f2.8. Lots of guys used to carry two bodies with both of those setups so you could cover basically anything.

That was before the mirroless and Sony craze though. If you're publication has enough resources, I could see putting a pit photographer with a pretty wide prime, but that would be kind of unusual even a few yrs ago.

Regardless, on a bright day with shallow depth of field, 1/8000 is not unheard of.

I’ve captured vapor trace several times over the years with both still cameras and video. It’s not that unusual and most times is dependent upon some backlighting.

And yes, I’ve captured it at lower ISO and FPS.

The photographer was stating that it was the vapor trail not the actual bullet

1/4000 or 1/8000 doesn't surprise me at all on a bright, blue sky day like that. Also, that may be the actual bullet or may be the liquifaction of blood/tissue from the hit. Or maybe boiling might be the better term.

I am not a “photographer”

But I have the gear, and it is a hobby


Having the shutter speed cranked up high in bright daylight when you want to capture something that may move is not uncommon. For example, a bird sitting on a bird feeder.

For a bright sunny day, I would have my shoulder speed cranked up

People keep saying Trump wasn’t a fast moving object in therefore it wasn’t necessary. But for photographer like this and your taking a picture of someone that is speaking and moving his head, you want the pictures to be crisp and clean and you were trying to catch hundreds of images, every few seconds to capture get that perfect facial expression or moment

Heck, when I’m taking a picture of one of my kids doing something or speaking somewhere, I usually have 2 to 300 pictures for just a one or two minute thing. Then I go home and sort through them to find the perfect one or two.

If you’ve ever been around, I’m using these cameras. The clicking sound is almost like a very fast machine gun. Each one of those clicks is an individual picture. It’s not a noise. The camera makes all the time that’s the shutter fluttering at an incredible speed catching hundreds of images.


Anyways, that’s my two cents

Correct. You need water vapor that is just on the verge of condensing. A vapor trail is caused by something to push the water vapor from the gas phase to the liquid phase. It happens on the trailing end of the object flying through the air (with a high concentration water vapor) because that is the location where the Joules-Thompson effect (aka, refrigeration effect) occurs and lower the temperature enough to bring the water molecules closer together to condense.

The good thing about Twitter under Elon, this Twitter post got community noted. When I initially posted this tweet it did not have the community note. Now it does which explains the photograph.


We have to move away from calling inquisitive people conspiracy theorists.

Today predominately on social media, including this place, is the location where questions, even stupid questions get fleshed out. More speech not less.

This

People that actually believe it was a setup and a photog was prepared to capture it are legitimate retards

Being you like to ask questions, ask yourself this question:

Do you predominantly, or even exclusively, ask questions that would serve to bolster your social and/or political beliefs, or do you just as doggedly ask questions that would utterly undermine your closely held beliefs?

If the latter, well, that sounds exhausting, but more power to you. If the former, you should give some thought about whether you're actually inquisitive, or whether you're so driven by confirmation bias that you've lost track of reality.

I'm human so I'm predisposed to doing this.

I feel like I do this all the time. I love being challenged. Helps me become more informed and at times reenforce or bolster my arguments and sometimes being challenged I get corrected or "knocked down a notch" so to speak. But that's okay. It's how it supposed to work, IMO.

I would use a fast shutter in bright light like that at any event that I’d expect folks to be moving around as well.

Use those kind of settings shooting birds all of the time.

Being open to being challenged isn't the same thing as actively seeking out information that would contradict your beliefs.

As an example, since this assassination attempt, I've watched some on the left assert that it was a false flag to solidify support for Trump; I've watched basically everyone on the right accuse them of being absolutely horrible people for even considering that as a possibility.

Yet, for the past several years, I watched some on the right claim every major public shooting to be a false flag intended to undermine the right, while the entire left accused them of being absolutely horrible people for even considering that as a possibility.

If it had been Biden on that stage instead, would you be on here posting about shutter speeds showing that this was a grand conspiracy that even the media was in on, or would you be reposting tweets talking about why this might be a false flag to save Biden's election hopes?
