Scott Highton has unveiled his VR photography website, which features a case study showing what goes on behind the scenes at a VR shoot; and a review of three multi-row panoramic panheads. The review covers many interesting aspects of multi-row panheads, such as space required for storage and carrying weight. In the review, Scott evaluates an issue few people may be aware of: the amount of deflection (or sag) of the panhead caused by camera weight. "This is a typical shooting problem, because image sequences shot with the camera as little as half a degree (0.5°) off of vertical alignment can cause noticeable stitching errors at higher resolution assemblies." He points out it is possible to correct for the sagging by inserting a shim at the appropriate place, but opines that this should not be necessary in expensive professional gear. IMHO -- every panhead I've ever seen suffers from the sag problem. I hope some organization with a big research budget thinks of a solution to this problem. 7:00:02 AM
