EX Cinegammas compared to Hypergammas

I just got this from Sony.

PDW-700 has HyperGamma (Ver1.2 or higher) such as,

HG1 : 325% D-range is compressed to 100%
HG2 : 460% D-range is compressed to 100%
HG3 : 325% D-range is compressed to 109%
HG4 : 460% D-range is compressed to 109%

These HyperGammas are the same as HDW-F900.

PMW-EX1/EX3 has the same CineGamma as PDW-F335/355 such as,

CINE1 : Same as the HyperGamma HG4
CINE2 : Same as the HyperGamma HG2
CINE3 : Independent setting for EX1/EX3
CINE4 : Independent setting for EX1/EX3


Therefore, please use CINE1 or CINE2 if you want to use the same gamma curve as PDW-700 or HDW-F900.

Thanks for passing that along!!

It's nice to have the hard numbers.

I always thought it strange that Sony didn't include any specific data about the Gamma settings with their literature. It's like being in 1985 and buying a computer that doesn't come with a manual!

Alister, it is nice to have those numbers, but they don't make total sense. Surely the highest range should be around 600% compressed down to 109%? 460% says to me that the full over exposure capabilities of the 2/3" sensor are not being used.

Somehow I suspect that Digital Praxis will show this to be the case with custom curves for the PDW-800.
