If you use a professional digital camera, you can't go far without understanding the relationship between sensors, lenses and depth of field. It's slightly more complicated than you might have thought!. Phil Rhodes makes it understandable
Somehow, I managed to overlook the fact that last month saw the death of Bryce E. Bayer, the man who decided that the best way to make a single-chip colour imaging sensor was to silk-screen a pattern of coloured filters on the front
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
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.
CMOSIS upgrades CMV12000 sensor to 300fps at 4k (4,096 x 3,072)
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
