By looking at the river you can notice a moiré pattern with lines both horizontal and vertical to the camera, although the vertical lines are more apparent. I figure these would be either artifacts from the stitching process, or limitations of the lens itself. The effect also correlates in size and shape with out of focus areas, which can likewise be found in the river, signaling that it is indeed an artifact caused by the panorama.

I guess you can take this as an exercise for the future when you can't quite figure out whether you are stuck in a virtual reality or not.

When you clear the cache or visit the site for the first time and zoom in, you can see the tiles load. These lines are at the stiching borders, and coming from the stiching algorithm.

Lens/sensor limit moire looks very different when compared to this.

Haha, I don’t know what I was expecting but that made me chuckle.

I wonder if anyone’s put together a collection of amusing “inadvertent Photoshops” from botched panorama stitching.

Nothing I’ve seen yet tops this specimen of neural net weirdness:

Am I the only one who gets a "FATAL ERROR: 404" message? I tried from different browsers on different devices. Wonder if they just block some countries?

Try adding a ? at the end of the url, for some reason that makes it work for me

Works fine. Latest Chrome. Europe.

Just checked, and it's down for me now (Bay area, California) whereas it was up earlier. Looks like Gigapan is down, too.

That's incredible. If you zoom in on the tippy top of huge building under construction across the river and then follow the crane cable down to the hook, you can see a construction worker in sufficient detail that you can tell what clothes he's wearing.

It's like one of those cop show computer lab scenes where the detectives find a vital clue from a witness' blurry 5 megapixel cell phone photo.

"Wait a minute. Why didn't I see it earlier? Zoom and enhance on that smudge!"

That is the most performant and responsive panorama I have ever seen!

It really puts map websites loading for around a second or more after panning/zooming into perspective.

It's interesting seeing how they dealt with moving objects like the boats.

If you scan anti-clockwise until the river is hidden behind the buildings you should see two tour boats with "China Bohai Bank" on the side. One appears to be pulling in and one pull out. If you look at the passengers - it's actually the same boat. If you follow the river clockwise, you'll see two barges carrying dark material. Again, these are the same boat.

I could be mistaken, but it seems in both cases that some 'manual effort' would have been involved to make the picture look natural by placing the duplicates slightly out of position as if they were two individual boats.

People too, unless this lady has an identical twin with the same umbrella https://imgur.com/NQ5keHY

I haven't seen any ugly merges between the frames yet, but they can't have been done manually

????

Of course.

You take these photos by mounting a dSLR on what is essentially a programmable tripod type thingy. It takes a series of photos, and all the images are stitched together in software. Depending on the software used, the algorithms will place things differently. Using different software to stitch the mosaic would result in, (probably), different artifacts in the final image.

Why would that be manual and not an artifact of movement between snapshots? If it were manual effort,why wouldn't they erase a duplicate?
[+] puranjay|7 years ago|reply
How are pictures like these taken? What kind of equipment would you need?
[+] jeffreymartin99|7 years ago|reply
They are shot with a dSLR and a very long lens. This one was likely shot with a 300mm lens. The camera is mounted on a programmable robot, and a mosaic of photos is created. They are then stitched together with software such as PTGui or kolor Autopano Giga. I've shot a number of images like this, in fact some of them over 4x bigger than this one. My largest one, of Prague, was released 2 weeks ago: http://360gigapixels.com/prague_gigapixel_panorama_900K_2018....

Phenomenal. Can clearly read the text on the billboards on the tennis court. "Twosome apply together second enjoy discount".

There's a lot to explore. I love that circular crosswalk. It also makes me smile to see the potted houseplants on the blue-roofed barge. Can't quite read the QR codes on the Disney fence, though.

You can see the amphibious warfare ship, Wuzhi Shan, being fitted out at the Hudong–Zhonghua shipyard.

I'm really surprised by how few people there are walking around on the street. You can see the people on the observation deck of World Financial Tower pretty clearly though.

This is my favorite photo now. I can relate my recent trip to Shanghai now. But these photos are very old I think because I'm missing tower inside the lawns of Disney store.
