This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.

More likely it's a single frame from a high speed shutter or high quality video. A lot of cameras I think can be set to do a rapid fire series of shots, you hear the clicks when you see them in movies or the news sometimes.

Okay here's the chance for a math wiz to step up, guesstimate the shutter speed, calculate the length of the bullet in the frame, and determine what velocity the projectile was going after impact. Why? I don't know. Science? Perhaps.

Mathematician here. Looks like it's going about as fast as a bullet.

Or just use plain old common sense, and realize that 5.56 usually goes about 3000 fps (or 900 m/s).

Ugh, I know it’s gonna be a waste of time but I wanna do it lol

The photographer talked on NPR about it. It was one of 40 photos he took during that time frame.

I know, I’m a sports photographer myself. The photographers probably had more or less 12fps set in the camera, more would probably be overkill for a journalist portrait basically.

Even so, you can miss something like this if you start taking photos too late or too early. I had this situation many times when a footballer goes for a header and I get a photos of the ball coming towards him and going away from him, but not the moment he touches the ball. 12fps means a photo every 83ms and you can still miss it. Not to mention a bullet going a bit faster than a ball. Everything happens faster than we realise.

Not to mention shutter speed, how fast the shutter goes down, exposing the sensor. Too fast and you won’t get that streak, too slow and you’ll entirely miss it.
