Abstract
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.
