This question was posted on Personal-View.com, the web site for micro four thirds (run by the author of the GH-1 and GH-2 hacks) and specifically the high end Lumix cameras.
Suggestion is made to consider using graduated neutral density filters or polarizing filters to help reduce the highlights in photographs. The same could be said for video, and that this tip applies not just to Lumix cameras but all kinds of still and video cameras.
I shot something recently, on video, using a Canon camera, where the subjects were in the shade but enough else was in direct sunlight. There was nothing I could do but allow the highlights to blow out on the limited dynamic range of 4:2:0 HDV video. But the suggestion to use a graduated ND is a good one that I thought worth sharing with others.
