High Dynamic Range (HDR) spherical images can be obtained without a
requirement for special purpose cameras having linear optical sensors.
Various examples of the present invention can use a standard single lens
reflex (SLR) camera with a fisheye lens to obtain spherical images. The
camera is positioned to obtain a plurality of images at different
exposures with the camera facing up and again with the camera facing
down. The images may then be processed to obtain an HDR spherical image.
A center post of a tripod, an offset arm and a rotational mount may be
used to position the camera. The offset arm and rotational mount can
enable the camera to be oriented straight up or straight down along an
optical axis separated from the center post of the tripod.
