Thanks for trying that out Liszon! It might very well be that the exposure of clips from the 'ungraded test footage' is a bit off, as they were really just quick tests. I hope we can provide you with better video material soon! Best Regards, Anselm Eickhoff

Hi Shijan, I'm sorry, but I'm still having a hard time exactly understanding your point. Have you looked at the full quality 10Bit download of the first video you posted? ([url=http://www.sinacam.eu/downloads/sinaCAM_ungraded_video.zip]Link[/url]) I guess you are talking about the trees at 0:07 as they are the darkest I could find in the video, but even though the forest isn't the target of exposure there are a lot of details in the shadows. In the sky there are sometimes hard bright spots, but those are areas that are lit directly by the sun and are thus [i]much[/i] brighter than the areas around it that show a lot of detail. You might be used to [i]lower[/i] dynamic range, where the transition between the bright and normal spots is smoother but you stop getting details much earlier. Now I also don't understand what the "bloodrop" video you posted has to do with it. There the sky is barely visible at all (overexposure, but used for artistic effect here) and the video is completely postprocessed and color-graded. The sinaCAM footage we have published so far is all completely ungraded, so you can see the quality of the base material the camera delivers. If you were to postprocess and color-grade it, you could get much more dramatic or interesting stylistic effects but you would almost always give up overall dynamic range in order to highlight the parts of the picture you deem important. Can you perhaps find a video of another camera with a similarly extreme light situation (shady precipice against dark sky) that doesn't have the problems you are referring to? If you can make your criticism clear, I can talk to sinaCAM engineers as they know more about the exact image processing and sensor differences and they will probably be able to come up with a better answer. Best Regards, Anselm Eickhoff Edit: Sorry if I hijack this thread so blatantly, but what people think about sinaCAM is of course important to us! Mods: feel free to move this discussion elsewhere or remove it completely, if you think this should be discussed in private.

BTW you can see same problem with SinaCam footage which also use those Kodak CCD sensor [url=http://www.sinacam.eu/media/]http://www.sinacam.eu/media/[/url] [/quote] Hi everyone, I'm the admin of the sinaCAM Website. As far as I know the Kodak CCD sensor was used for sinaCAM exactly because of its [i]good[/i] dynamic range compared to equal-size CMOS sensors. Shijan, could you please tell me in which of the videos specifically you see overexposure/too little detail in the highlights or low dynamic range? Thank you, Anselm Eickhoff
