Anfy Panorama images creation
The Anfy Panorama applet could display any image in panoramic view, but of course only the
ones made with special 360 degree optical cameras will look perfect.
The exact format is: spherical panoramic image with 2:1 size ratio (equirectangular).
This means, the image should cover 360 degrees horizontally (pan from -180 to +180) and 180 degrees vertically (tilt
from -90 to +90), and the image width should be 2 times the image height.
Cylindrical panoramic images like the QuickTimeVR ones (covering only the horizontal
360 degrees) could be used, also if size ratio is not 2:1 (you may stretch the image until
you reach better results, or use conversion tools). If using cylindrical images, the vertical
tilt should be limited, for example ranging from -20 to +20 rather than -90 to -90, since
the photo does not include all the 180 vertical degrees of a spherical view.
To see how these images look before being processed by the applet, just load the sample
ones provided in AnfyPanorama with a normal image editor.
How to create cylindrical panoramic images with photo cameras:
You may try placing a normal photo camera on a tripod, pointing to the horizon
and taking a dozen or more photos, rotating to the right the camera by an equal angle between each shot.
Then, you have many different photos taken from same point to the 360 degrees environment: be sure
to don't move up or down the camera but only rotate it. The photos should overlap by 25% on
each side or a bit more, but not more than 50% of what you was seeing in previous photo should
be present in next one. Also, be sure to set the exposure in a way that all the photos have
very similiar light (or retouch photos later).
Then, you can scan/digitize all these photos and merge them with a paint program or (better)
using a more specific stitching software for panoramic images creation.
This technique is the cheapest, and may give acceptable results for hobbists, but
of course there is much work in photos merging and the approximation will be visible.
Otherwise, you can search for a swing lens panoramic camera like The Noblex 135-S (136 degrees),
or a japanese Widelux F8 (it has a 28mm fixed focus and lens rotates to cover a 140 degrees),
or a russian Horizon 202 (120 degrees). However, even if these are panoramic
cameras, them can't provide a full 360 degrees cylindrical photo, and then
three 120 degrees photos should still be merged.
Some rotating cameras are also available, such as the SpinShot, the Hulcherama,
and Globuscope: these can capture a 360-degree image by revolving in one direction while
the film moves in the other so it's synchronized with the lens motion.
Please note: all these techniques can't produce spherical panoramas where you can
watch up to the sky on the top and the ground on the bottom, but only cylindrical
ones with any or minimal vertical tilt allowed.

Here is a list of companies able to provide cameras for creation of
360 degrees horizontally and 180 degrees vertically wide spherical
panoramic images, for use in AnfyPanorama applet.
