If I should try another player let me know!
it's ok, let me do a bit of research first

Wow, marz, that was a powerful post!
From what I can see, everyone who reports shortcomings with the camera is respectful to the developers etc, does appreciate the support and effort that is being put in to make it an even better product.
I don't know what "chill pills" contain in your part of the world, but if someone perceives there to be an issue, and in this case a demonstrable issue, what is wrong with them highlighting it - that is how things get resolved. Chilling out over the issue doesn't help get it resolved. Do you think people are being unreasonable over this?
As dashmellow already mentioned, the dynamic range is not optimal yet. This is on CENTER with WDR ON.
As you can see the weather conditions are excellent.
Guess the AE emphasis is still too much on the top part of the image?
yeah we haven't got into the contrast and brightness tuning as yet, getting the tables right is first, will have another update soon, still doing some work on that, the file you sent will help, thanks for that
not EVuser control for brigntness? That would be the EV right?
not sure at this stage if Gamma is something we can adjust or it's fixed, it's something that will be looked at further though

In my minimal understanding of how this works, the sensor would inherently have certain characteristic gamma values and the DSP needs to properly map those values for the desired output. I believe it is accomplished with a LUT similarly to the AE LUT. For some reason that seems to be a difficult task with this particular sensor/DSP combination for whatever the reasons, as if the camera is properly mapping the exposure values but not properly mapping the tonal values.
yeah I'm not sure what adjustment is available at this stage, I have another model based on a different solution that we've been working on and the engineer made a gamma adjustment as that is an available option and it made a total mess of the output, that could have been a mistake on the engineers behalf though, not entirely sure at this stage, sometimes these things get lost in translation so it could just be a communication error that lead to the end result, I'm back in China in a few weeks time and will be working on this, I find I get a lot further with this kind of thing when I'm in the same room as the engineers
This makes me worried...If your engineer knows how to adjust the gamma but doesn't understand the concept of how it actually works

If your engineer knows how to adjust the gamma but doesn't understand the concept of how it actually works he could easily make it all worse. It is confusing, in part because it is an inverse curve intended to bring the values back to linearity.

Well, it could well explain all the problems here. To be perfectly frank about the whole thing, I have speculated as to whether a different group of engineers might possibly do a better job with this camera.
