Over the last
10 years of being obsessed with photographing panoramas, I have come
to consider spherical images the ultimate in pano photography. These
cool images not only let the viewer look around but also include the
up and down view of a location.
There are several
ways of creating spherical panoramas, the 4 main methods is listed here.
- Multi-row panoramas,
where the photographer photograph several rows of the panorama, this
involves many pictures and can yield extermely high resolution images
if so desired. Advantages: inexpensive, equipment. Disadvantage is
long photography time and large numbers of files for each panorama.
- Single shot spherical.
Created by photographing a reflecting
sphere, this type require the photographer to photograph a up
and a down picture and add these to the final result. Advantage, very
quick photography. Disadvantage very low resolution because the doughnut
shaped file only use about 1/3 of the image file.
- Spherical Fisheye panoramas.
Photographed with a fisheye lens with a field of view greater than
180 degrees. Advantages, quick photography, great utilisation of the
image area resulting in rather high quality panoramas, relative inexpensive
equipment. Disadvantages, sentisive to lens flare.
- Rotating Scanning back
cameras. Such as the PanoScan
digital camera and the RoundShot
Film based camera. These are cameras which slowly rotate while
photographing a complete panorama, there is virtualy no limitation
to the quality of the image or the size of the file. Disadvantages:
HIgh Price in the $10.000 range. Large size, and suporting equipment
requirements, not ideal for light traveling. Slow scan times, making
them unpractical in areas with rapidly changing conditions, souch
as the outdoors, or where large numbers of people might be in the
picture.
All of the above
processes will produce a beautiful spherical panorama. However the fisheye
seem to be the most interesting. After Nikon came out with a inexpensive
fisheyelens for their digital cameras, this process have become the
....... Tools are readily available, the Nikon lens can be purchased
for about $300, and tools such as the 3D-Vista
package will let you stitch these images easily The Njkon fisheye is
available in two versions, a 53mm lens tread version and a 28mm lens
tread version. With few exceptions most cameras require the larger diameter
lens in order to fill the image area. I prefer the 3D-Vista stitcher
package, because it is easy to use, fast and offer advanced features
such a outputing layered Photoshop files or cubefaces, to mention only
a few.
