= Yosemite, hugin, nona, and enblend =

Here's three snapshots of a waterfall I saw, merged together.

It's twice the height of Niagara Falls. so I took three vertical shots in landscape orientation zoomed out as far as my lens would go.

Came out pretty well, I think.  Yes, that's a rainbow from the mist that was getting on my camera.

I used autopano-sift, hugin, nona, panotools, libxmi, enblend, and gimp to process the images.  What used to take hours of painstaking by-hand assembling and blending now is done by the computer in minutes.  It's in equirectangular projection.

There's also a slight trick with the polarizer.  The top two photos were polarized to suppress reflection to bring out the water against the rock.

The bottom one is with polarized light passed through to get the rainbow reflection properly, which also contributes to the extra mistiness near the bottom.  So you really couldn't take this picture with a single photo.

86x98 degrees field of view!  Imagine it plastered on a wall ten feet high (but curved on a square arc of a partial sphere quadrangularly), stand five feet (half the height) away with your eyes 5 feet off the ground to get an equivalent view of the camera.

The next image is also pretty good, but I overexposed the top.  It's due to not changing the exposure to do high dynamic range compositing later (since I had only room for three more shots).

It's of the Grizzly Giant in the Mariposa Giant Sequoia Grove.  Three portraits merged together in transverse mercator projection (so as not to make Rickie show out of proportion).

There are 50 degrees of horizontal field of view -- but 107 degrees vertically, just to demonstrate the size of the tree!

The last image is a cylindrical projection panorama with vignette correction.  On this image I should have corrected the polarizer for each shot, but neglected to and had to do a little post-processing.

Hugin did a pretty effective vignette correction, and autopano-sift did an excellent job fitting the images together.

This is four landscape shots with a total 54 degree vertical field of view and 224 degree horizontal field of view, which required a cylindrical type of projection (as opposed to a flat projection).

The subject is Little Yosemite above Navada Falls on the northern side.
