Internet forums, YouTube and magazines are full of articles extolling the virtues of large sensor video cameras, whether it's the Red Epic or the Canon C300. But should we be obsessed with the Big Chips, or do they have a downside as well. Kieron Seth investigates.
As we saw in my previous article on sensor technology, we can now build sensors with enormous numbers attached to them - if not trivially, at least reliably. Given that current 4K sensors are more than adequate to replace 35mm film in terms of sheer resolution, we need to be careful about turning this into a numbers game.
Most large-sensor cameras use a Bayer colour filter pattern to allow full colour images to be output - after "debayering". This entire process is now pretty routine but unfortunately what is also routine is the amount of light lost through the colour filter process. Less light means more noise, and noise is what ultimately limits the low-light capabilities all cameras
If you're one of the people who's preordered a Blackmagic Cinema Camera, unless you're very lucky, you will probably have noticed that you don't actually have one yet. RedShark, in common with the rest of the world’s media, is eagerly awaiting the arrival of a camera to put through its paces.
Over the weekend we brought you the first images that were from the new RED Dragon sensor. We thought they looked sensational, and said so, but before everyone (including us) gets carried away, it's worth injecting a note of caution into the frenzy that surrounds this new sensor
