This page provides several preliminary demonstrations of High Dynamic Range (HDR) panoramas. These are based on thesis work with my supervisor Dr. Jochen Lang. The panoramas were captured using a Point Grey Research Ladybug2 and custom capture software. These panoramas have not had any deghosting algorithm applied and may therefore show minimal ghosting in some areas.
- These use Microsoft’s HDview plugin, which offers linear and logarithmic tonemapping; make sure to enable tonemapping by clicking the tone adjustment button or pressing ‘t’. If you don't have it already you should be prompted to install it. If you're on a Mac, it will install HDview-SL which does not currently offer the HDR functionality of HDview, but should still let you see the panorama.
- HDview uses a multi-resolution pyramid storage scheme with JPEG compression. I've used 75% compression to speed things up a bit but there may still be some buffering delay. If this is a problem, see the alternate link below.
- HDview steals your keyboard and mousewheel functionality. If this happens, use your mouse to click your broswer's back button to get out of here.
- The Ladybug2 has a fairly low resolution of about 4.5 MP over the sphere, so you can zoom in but things won't look great past about 2x zoom. This is a HW limitation.
If you have trouble viewing these panoramas, try going here where you can view them individually.

To get a good feeling for the HDR aspect of this scene, switch the tonemapping (flat line button) to linear (straight 45 degree line), then zoom in on the farther windows.
Note: the windows were unfortunately quite dirty at capture time, that is not an imaging artefact.
