Filmmaker Philip Bloom, die onlangs nog zijn drone liet filmen in Thailand, heeft een eerste videotest van de Sony A7S online gezet. Philip heeft vooral de enorme lichtgevoeligheid van de 12 megapixel-sensor getest. Eerdere video’s die we zagen waren al indrukwekkend, maar deze beelden mogen er ook zijn. Philip testte verschillende ISO-standen op een donker strandje in Brighton. Hij laat daarbij duidelijk zien hoe de scene er ‘normaal’ in het donker had uitgezien en wat het effect is bij hoge ISO-standen. De uitkomsten zijn enorm indrukwekkend… nacht lijkt haast dag. Je ziet meer details dan met het blote oog…
Philip zegt er zelf het volgende over:[quote align=”center” color=”#999999″]
James Miller and I went down to our favourite shooting haunt, Brighton with our matching A7s to see what we could get and try out different profiles. James shot mostly S-Log. I mostly shot various Cine gamma modes.
Pointing away from practical lights so I could push the ISO up to see just how far you could push it. Just how much can you see in the dark?
Brighton Beach has no lights on it of course. There are lights on the promenade but there are a lot of people who sit out there in the dark that you can barely see with your eyes. This camera though? Well take a look!
I shot most of the daylight stuff at ISO 100 in Cine Gamma 4 and S-Gamut colour. A very flat image, not quite S-Log but close.
My glass was: Canon 24-70 F2.8II, Canon 70-200mm F2.8 IS II, Sigma 35mm ART F1.4, SIgma 50mm ART F1.4
I used the Small HD DP4 as a monitor/ viewfinder, additionally I had a Tiffen variable ND filter and my Really Right Stuff tripod with FH-350 head. To top if off I also had my new Special Edition Kessler Crane “Burl Wood” Pimipn’ edition for the odd slider move!
With the shots where in goes from dark to light and vice versa, these dark parts are what I could see with my eyes. They were all shot with high ISOs and graded down to show you what I could see and what the camera could see if it was set to around 800-1600iso as opposed to what I actually was shooting at. At night between 6,400-80,000!
It was incredibly dark out there so even though I could see everything way better than my eyesight could some of the shots with dark area in them were just too noisy not to fix. I used the ever marvellous Neat Video to get these results.
So there is no cheating here by grading it dark. I made it look exactly as it would do and to prove it watch after the credits for a shot where I cycle through the ISOs![/quote]
