HDR videos

Some users have created HDR time-lapse videos with their Canons. The
technique is quite sim ple: set the camera to bracketing mode and config-
ure the Custom Timer as discussed in section 6.2. Then use any time-lapse
script that can press the shutter button in defined intervals, such as the
script developed in section 5.7.1. Again, be sure to have fresh batteries and
rather large memory cards on hand (see appendix A.1 for running the
CHDK with memory cards larger than 4 GB).
The resulting bracketing series must be processed with an HDR com-
poser. The composer should be able to combine images in batch mode
Make sure that tone mapping is performed with the same parameters for
each bracketing series. The result should be stored in the form of JPEGs
that are then combined into a movie with a time-lapse converter (section
5.7.1).
1 Photomatix Pro, FDRTools Advanced, Dynamic Photo HDR all have batch
facilities.
