What camera are they shooting at 409,600 ISO at?
- jeswin 6y agoThe Sony a7s and a7sii have a native iso range of 100 to 102400, which can be boosted to 409600.
- Traster 6y agoIn the video they reference the Sony A7S II, on Sony's website[1] they claim: >Still images: ISO 100-102400 (expandable to ISO 50-409600), [1]:https://www.sony.co.uk/electronics/interchangeable-lens-cameras/ilce-7sm2#product_details_defaul https://www.sony.co.uk/electronics/interchangeable-lens-came...

Unlike film, adjusting the "ISO" in a digital camera doesn't increase sensitivity; that's physically impossible. Instead, very strong overgain processing is applied. So in this instance they're processing lossily on top of an image already processed lossily in-camera.
- anigbrowl 6y agoThe A7g image is used for comparison rather than input data, as that camera is widely regard as the state of the art for low-light photography on a non-scientific/military budget.
