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.
To mark the occasion of the new year, our editor has asked me to come up with some predictions for the coming twelve months
Recently I've been expressing the view that all cameras are pretty much the same, because they all use the similar technology (give or take) for their sensors. I don't mean to be unnecessarily cruel about the work of camera manufacturers – taking an electronic component such as an imaging sensor and making it into a usable tool is far from trivial. Still, the absolute performance of cameras is determined by what you can get off the lump of silicon behind the lens
Scientists at Nanyang Technological University in Singapore have developed a new sensor technology based on Graphene, which is 1000 times more light sensitive than existing CMOS or CCD sensors
