  • Sometimes you need to combine bracketing with variable raw processing within each exposure level. Modern stitching softwares will do a good job of blending changing "virtual exposures" within a constant exposure layer so long as you change the effective EV gradually around the panorama. This art installation of giant syrofoam chains in a dim factory interior was sunlit in parts and...

  • With panoramas (spherical ones at least) good composition often involves having strong perspective cues. Scale and converging lines and haze for example. The viewer will feel more immersed if it is clear where the viewer position is. (About scale, the size of the hazy sun in the recent Mars panorama caught my attention.) So having figures in the scene, or a high enough viewpoint to...

  • Deshaker for Virtualdub works pretty well for this http://www.guthspot.se/video/deshaker.htm .. and removes rolling shutter as well to some extent or PTGui will do it if the camera is not moving through the scene -- I often use PTGui for stabilizing static handheld fisheye movies or if you know your way around Blender 3d here is a workflow from Photoscan 3d http://www.agisoft.ru...

  • http://www.mediavr.com/whalenewport/whalenewport.html .. here is a pole scene - with a 5m elevation - of people coming to see a dead whale on a Sydney beach a couple of days ago (the whale is in the rock pool). This is with a Nodal Ninja pole -- supported by the levelling base I've been using for metal pole shots previously. http://www.mediavr.com/levellingbase.jpg Before I got the...

  • http://www.kickstarter.com/projects/1523379957/oculus-rift-step-into-the-game Head mounted displays are a really compelling way of experiencing stereo panoramas (or regular) panoramas -- particularly if the field of view is very wide and the displays are tracked with a very low latency, accurate head tracker. This crowd-sourced project promises to deliver such a HMD for $300 or so...
