Amazing! See the World's Largest Spherical Photo, 18 Gigapixels

| by DeepDiveAdmin

Jeffrey Martin from 360Cities spent over a month stitching together what he (and TechCrunch) believes is the largest spherical photo ever created. Click on the link below and take an panorama view of Prague -- and spot license plate numbers from literally miles away.

A lot of people are curious about how exactly an image like this can be made
at all. So, we’ve compiled the most basic questions and written some answers. If
you have another question, be sure to leave a comment below.

The Prague 18 Gigagpixel image was shot from the top
floor of this tower.

From Martin's blog --

How did you create this panorama?
I used a Canon 5d mark 2 and a 70-200mm lens, set to 200mm. The camera was
mounted on a robotic device which turned the camera in tiny, precise increments,
in every direction. All together, 40 gigabytes of images were shot. These images
were then stitched together using PTGui. The resulting panorama was adjusted for
color, contrast, sharpness, etc. in Photoshop. Afterwards, the image was cut
into lots of “tiles” and uploaded to our server. When you view the image online,
you only load a few of these “tiles” at one time.

How long did you spend stitching this panorama?
Between loading the initial raw files into the computer, and having the
panorama stitched, it took about a week. It took 3 additional weeks to fine-tune
the image.

What kind of computer did you use?
I used a four year-old windows PC with two single-core 3ghz xeon processors
and 8GB of RAM. After a week of frustration, I also bought an SSD, which helped
to speed up some tasks a bit. If I will make this image again, I will buy a new
computer.

What is dimension of this panorama, and size it takes on disk?
The final image exists as a 120 gigabyte photoshop large (PSB) file. It
cannot exist as a TIFF or JPEG file because of their size constraints. The
panorama online exists as a few hundred thousand small tiles (in JPEG format),
and they take up about 1 gigabyte of disk space.
