Says everyone: (Banding = Structure of sensor + defective product) Well, why clean photos? I suspect that the GH1 orginal software! What do you think this suspect?
12bit vs 8bit.
How many video bits in gh2 ? 12?
GH2 and nearly all prosumer cameras are 8 bit. Which equates to 256 luminance values vs 1024 in 10 bit. So if you imagine a smooth gradient with almost infinite subtle shades and you have to reproduce it using 256 values vs 1024... you have to make the cutoff somewhere. It's like trying to make a circle with straight lines, the more you have, the smoother the circle will be and have less 'stair-steps'. It's not the sensor. It's the processors and software used to encode it.
Guys, first, we already have topic about banding. http://www.personal-view.com/talks/discussion/202/banding#Item_45
Second, it is impossible to understand that you are talking about and all this things about 12bit in JPEG photos.
