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.

Earlier quoted context omitted.

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://360gigapixe…

Wonderful pictures. The 360 views really help capture the feel of the city. Wish there was a way to fix the black hole at the bottom, though.

Sure there is, you can paste a satellite photo of the ground where you shot the photo from ;-)

Prague link fix: http://360gigapixels.com/prague_gigapixel_panorama_900K_2018... How long it takes for robot to take all the pictures and how many pictures there is?

Prague was 3 hours per dataset. I was there for 3 days in the cold and rain, shooting multiple datasets, from 8am to 4pm last year in November.

Thank you for the amazing works. There is a type in the copyright footer on your website, it states (c) 1066 - 2019

I was around since the Battle of Hastings actually, so it's not a typo.

Thank you for noticing ;)

How are pictures like these taken? What kind of equipment would you need?

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 ar…

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.
