This is a fascinating article that covers something I've thought about plenty of times! Genuinely how often do people take virtually the same photo at the same time? You'd think it'd be more often at places like Disney World but it's fascinating to hear it happened in a scenario like this.

A couple was captured in the same photo at Disney years before they met: https://disneyparks.disney.go.com/blog/2010/06/couple-knows-...

I met First Wife at a festival. I sent my brother a photo of her from the day I met her. He sent back a near-identical photo of exactly the same woman in exactly the same position from the day before when he had been at the festival himself and took a photo of her lol.

That's not an example of a distributed system, so it doesn't really clear up whatever the GP was trying to say about time in distributed systems at small scales. But even if it was this is nonsensical. The visual content of a photo is generally not what is used to determine the moment in time when it was captured. There's metadata in the image format that specifies when the photo was taken. There are pictures taken a…

The distributed part is the clocks on the cameras across the world. The article discusses the timestamp is included in the exif data embedded in the jpeg file. The clocks are most likely synchronized based on gps assuming they’re already pulling location data from the satellites, the time is “free”. However, the precision of the clocks is not specified and like any process is subject to error. So at the small timefra…

Whoever arrives first? Since they can't arrive at the same time because of sequential processing at the final step. So the guy who implemented the system will be the arbiter of truth.

(I realize that there are a few details that you can use to tell these apart, but,) Who gets to register the copyright on the image?

The scene is not subject to copyright (naturally occurring). If we pretend that camera sensor captures are exactly the same, then I guess it does not belong to a single photographer in this case. But usually no one cares about sensor data, people care about "deliverables", like JPEGs or printed versions, and they will not be the same because everything after sensor capture would be different for each photographer.

What do you mean by "scene"? Like, the state of the world at the time of the photograph? Why would anyone think that was "subject to copyright"?

Photons mostly

Scene itself is absolutely ""subject to copyright"" in many cases, like when it's set up by photographer or includes recognizable people (they can sue you if you sell a street shot with their face)

Or maybe it says that we all see the beauty around us, but we don't notice everyone else seeing it, too. (More than one person stopped, but only two people knew that.)

Why only two? In fact, several of those who stopped to take the picture were also informed by a neighbour (each time a different one) that others had taken the same picture before.

At least if the woman in the house was good at forgetting and asked everyone if it was a class assignment? :-)

In fact? How do you know that?

What?

Think of it this way: you run a website that displays photos in chronological order. You receive these two photos. Which picture was taken first? How can you tell?

I've looked at user telemetry and the conclusion I've come to is that the only time you can trust is from systems under your control (i.e., submission time).

In a way this says something about human brains. Presumably both people took many pictures of many waves that day, but somehow both of them decided that this is the one that is the best from that trip. As humans we share a similar metric for beauty. I find this idea simultaneously obviously and amazing.

This is ultimately a study in bias and how we choose to take pictures of the same things.

I remember being struck by this when Microsoft Research first started releasing their photosynth technology, some of the demos showed raw flickr dumps for certain large cities, and there were massive clusters of photos around the most famous tourist bits. In fact, the technology somewhat relied on this overlap.
