All we got from NYT: quote:Law enforcement officials recovered an AR-15-type semiautomatic rifle from a deceased white male they believe was the gunman at the scene, according to two law enforcement officials. The federal Bureau of Alcohol, Tobacco, Firearms and Explosives, as part of its standard procedure in mass or high-profile shootings, is running an emergency trace on the weapon using its national firearms purchasing database, which could be critical in definitively identifying the shooter. Could've also slowed down with my not-a-bullet-but-shrapnel theory!

It sounded off in the video, which was why I assumed it was a stunt at first. I'm going to bed he missed either from a unzeroed optic, or he didn't account for the bullet drop as 9mm goes subsonic. I think 9mm is sub at that range, but I'm probably wrong.

You absolutely know better than I do on this topic, but the one video with the audio feed from the mic trump was talking into had a slight delay between the little thwack of a rifle round going past just a teeny bit before the boom from the gunshot reached the mic. Maybe. I'm guessing.

I wouldn’t put any weight on the specific figure. All I was saying is that the image isn’t inconsistent with parameters of a real photograph. The possible solution space is vast. It wouldn’t be unreasonable to have a two-thousandth of a second shutter interval, even higher. The lens may go to f/2.8, implying up to four times the bullet speed, and the editor’s not going to fire anyone for turning in photographs with noise levels of ISO 800, so the real limit is just whatever the camera is capable of, one eight-thousandth of a second, maybe. There’s rarely much reason to go that high, but on a sunny day, you can. One two-hundredth of a second, implying a much slower projectile, would be less likely because it risks blur from camera shake and/or the subject moving, but it’s not out of the question. There are also the trigonometric factor if the line of fire isn’t parallel wit the image plane, but this is small compared to the unknown of shutter speed.

The New York Times has an article (archive) on the photograph itself now.quote:Mr. Mills was using a Sony digital camera capable of capturing images at up to 30 frames per second. He took these photos with a shutter speed of 1/8,000th of a second — extremely fast by industry standards. Maybe it’s less than the foot long I estimated, maybe it’s coming in further off-axis, and maybe the rolling shutter elongated the trail, but in any case, that’s a fast projectile.

high as gently caress shutter wide open (to blur the people in the background as much as possible) makes sense on a sunny day. i dont think there's much reason to decrease shutter for human subjects unless you're trying to get motion blur, so you may as well max it to keep exposure down when it's bright out still a hell of a lucky burst though--even though you basically can run modern sonys at full tilt continuously you probably still pace shots a tad over a long rally unless you wish pain upon your editing team rolling shutter (rather, rolling sensor dumping) may have been a factor but there's a decent chance the photog had an a9iii Qtotonibudinibudet fucked around with this message at 07:40 on Jul 14, 2024 |

Qtotonibudinibudet posted:rolling shutter (rather, rolling sensor dumping) may have been a factor but there's a decent chance the photog had an a9iii I haven’t kept abreast of camera development. What’s special about the A9iii here? e: Oh O.K. they prominently advertise a global shutter, an “industry first”. Anyway, this only really matters if the image was portrait (usually, some sensors might dump by column). If the rows that the projectile are in were dumped in sequence, at worst you’d get a little bit of a parallelogram skew to it. Platystemon fucked around with this message at 07:57 on Jul 14, 2024 |

Platystemon posted:I haven’t kept abreast of camera development. yeah, modern best in class sensors just don't have rolling shutter anymore, though it's something you pay out the rear end for and don't need 99% of the time. this is the 1% where it'd matter. even if not that yeah, rolling shutter usually presents as distorted vertical lines, less so horizontal

Asking as someone who doesn't know much at all about cameras, what's the functional difference between a still camera taking photos continuously and taking still frames out of the video cameras that were probably pointed at the event - do still cameras use a resolution that would take too much storage to just record as video?

Yes, by a lot, and it’s not just resolution. Compression and the bits per pixel and color subsampling all hurt the quality of individual video frames. Still cameras are employed very differently. Because they’re not tied to capturing a continuous take of the whole speech, photographers can move around for different angles and reframe in ways that videogaphers cannot. Maybe they miss the moment, but maybe they nail it, like Mills or like Evan Vucci did yesterday.  Video frames will not have been captured at one eight thousandth of a second, either.

Is it just me or is there still surprisingly little being reported on the shooter and his background? Usually by this point a mass shooter would have his whole social media profile/activity all over the place.

So he wasn't the type to shoot his mouth off all over Facebook/Twitter/Instagram. Think more like the Vegas Mandalay Bay shooter than anyone purely politically motivated. I'm thinking more along the lines of a school/spree shooter.

Definitely possible. My current theory is that they know enough about the guy to know that he was definitely right leaning and likely a Trump supporter. They're gonna find out he was trying to martyr him or prove that he's sent by God or some other absolutely batshit thing. Even if Trump was genuinely shaken by this, and I think that's super likely even if it's temporary, I can't see the cooldown in rhetoric from everyone else without there being more known about the guy even if the motives aren't clear.
