Introduction to VR equipment
For great full-360 photography,
you need a Digital Camera, Fisheye
Lens, Panohead and Tripod.
VRstitcher Fisheye Pro stitches
the 3 different fisheye image types created in full-360
photography:

VR Equipment Summary |
|
Digital
SLR Camera
Digital SLR cameras,
give photographers the best of both worlds; high quality
full-360 images, plus SLR lens flexibility. |
|
Fisheye
Lens and Adaptor
A fisheye lens
is an extreme wide angle lens, that captures
180° in all directions (circular fisheye), or 180°
across the diagonal (full-frame fisheye).
dSLR photographers can use either the 180° circular
fisheye lens, or the full-frame, diagonal fisheye lens.
A full-360 spherical panorama
is created by stitching together 2 or 3 circular
fisheye photos, 4 cropped
circular fisheyes, or 6 full-frame
fisheye shots. |
|
Panohead
Rotator and Tripod
A PanoHead rotator and tripod,
aligns the fisheye lens/camera so the photos may be
taken at precise intervals.
Attached to the tripod when shooting,
it eliminates the displacements between hemispheres
and ensuring seamless stitching.
PanoHead rotators are available
for digital SLR cameras, as part of the VRstitcher
Full-360 Kit. |

Fisheye Image Formats |
Digital
SLR cameras - Cropped circular fisheye images |
 |
Cropped fisheye images
are created when a circular fisheye lens (eg Sigma 8mm fisheye),
is used with a digital SLR camera.
Because the focal length multiplier of most dSLR cameras
is greater than 1, the edges of the circular fisheye become
cropped. |
|
Therefore, while 180° is captured
vertically, less than 180° is captured horizontally.
This means that in order to get full-360 coverage horizontally,
4 shots are required.

Digital
SLR cameras - Full-frame fisheye images |
 |
Full-frame fisheye images
capture 180° view across the diagonal of the image, using
lenses including the Nikon 10.5mm and the Sigma 15mm.
As a result, 6 shots are typically required to capture a
complete 360° horizontal view. |
|
Because full-frame fisheye images
do not capture 180° vertically, they do not produce a
complete floor-to-ceiling view.
The main advantage of the full-frame fisheyes, is the very
high resolution panorama that can be achieved.
