The Tower Panorama

Unlike a classic 360°x180° panorama, a tower panorama is not taken from a single center point.
Imagine yourself on a tower with a viewing platform. You can walk around, but usually you cannot position yourself in the center.

The way to create a 360° tower panorama is to take multiple segments from each side. Using a fisheye to cover the entire side is not an advantage here. Taking multiple segments is better to allow for more correction of the parallax error.

Perfectly square

How to make a rectangular object perfectly square using the panotools:

In this example the frame is straight, but somehow the photo looks distorted.

Panotools Projections

The most common Panotools projections are Equirectangular to make interactive 360x180 panoramas and Rectilinear to fix distortions of photos. But what about the others?
With a small Field of View (FoV) the difference isn't that obvious, but with a large Field of View things change quite a bit.

Imagine yourself standing in front of a large object and try to take a photo. Using a wide angle lens will get you visible distortions once you go above 50 degrees (100 degrees FoV) because of the Rectilinear projection.
Here is where the other projections come into place to map large Field of View objects to a print.

This is an example of an extreme Field of View, standing right in front a Ferris wheel taking several pictures using a 24mm lens:

The quick shot

You got your camera with you. Great. You have your tripod along with the panoramic head next to you? Probably not. Unless you go for the architectural motive, using the right control points gets you quite far.

This panoramic image is composed from 4 individual pictures using a 24mm lens on full frame without the use of any panoramic head:



One row with three consecutive pictures and one to make sure the interesting part at the bottom isn't gone in the final cut:

Lewis and Clark, The End Of The Trail

Seaside, OR
Finally a sunny day in the summer and I decided to get a 360x180 from Lewis and Clark.
This is a handheld spherical panorama made from 4+Z+N (4 shots horizontal and 1 up, the Zenit, and 1 down, the Nadir):

Seattle Center Fountain, One shot Panorama

A circular 8mm Fisheye on a full frame 35mm Camera covers 180° horizontal and vertical. See how to make a panoramic picture out of that.

McCaw Hall, Seattle, WA

Located north of Seattle Center, the McCaw Hall is a performance hall and opera house.

While walking along Mercer St, I noticed a convoy guarded by police on motor cycles. Not that this is unusual here, but this convoy didn't seem to end. The convoy finally ended with 3 coach buses and a medical ambulance, while I snapped this panorama handheld.
Once they past, the almost empty Mercer street was opened again for traffic on Friday, June 18. 2010 at 2.35pm.
