Looks like this could be a browser problem?

Love this type of composite photography, really gives a fun perspective of a location.

rubyn00bie• 3 years ago

This is awesome. Is there a version of this, or something similar, not using Perl? I have nothing against Perl other than I’m absolutely shit at it and have zero incentive to get better (except maybe playing with this).

OO000oo• 3 years ago

Why?

esafak2• 3 years ago

So you can show the passage of time in one image.

TIL this is a reliable method of time travel.

taneq• 3 years ago

For landscapes these are great. For action shots I’m a fan of the long-exposure-plus-flash approach where you get a sharp freeze frame overlaid on the motion blur showing the movement.

It would be interesting to see this concept extended into time-lapse video. The day/night segments of the video could shift to the right with the passage of time.

mazzystar• 3 years ago

I think it won't move. As the segment is extracted by current time, it's somehow similar to record a video from day to night. Tell me if I'm wrong.

This is really really cool

One nitpick:

a photograph, an inherently static medium

At least on a computer screen, it is far from static

Just displaying a photograph requires looping through the whole thing multiple times per second, both to refresh the display and to draw the image

And even a static photograph usually contains enough time information to be compressed quite a bit

lukevp• 3 years ago

This is more than a nitpick. If you want to define static in a way not implied by common usage, you could say that even a blank piece of paper is not static because it’s made of atoms, or orbiting the sun, or whatever. They clearly meant static in the sense that it’s not a video.

nico2• 3 years ago

No one intended redefining static, just pointing out that a photograph is most definitely not static

And as you point out, everything in the universe is moving, which is actually a big deal that we don’t consider nearly enough, and which we tend to completely dismiss as if it was the most obvious thing in the world, like you are doing with your comment

Not the same concept, but in terms of extremely long exposures I love these images too:

I'm actually working on my own implementation[0] as a standalone binary to avoid dealing with Perl and its dependencies and as a collaboration with my nephew, who is learning new photography styles and techniques.
