Just thought I'd share this valuable info. for those who own GH1s.
There's a great thread that shows some pretty amazing images using a firmware created by tester13 on DVXUser forum.
Here is the thread by Michael Pappas.
I find this interesting especially for still photo use. The image quality is quite amazing and I may try this approach for still pics. It basically shows that when tweaked the GH1 is a very capable camera for pictures and film.
