Story from dpreview.com:

"Canon has launched a site promoting its CMOS sensor technology. This site is broken into four sections; Image capture, Technology, Full-frame appeal and Shooting options. It's an interesting insight into why Canon believe they have the edge in sensor technology and also exactly what goes on inside the sensor at the time of capture."

Even though much of the science has been bowdlerised beyond common sense:

Quote:
Given two cameras with the same number of pixels, the one with the larger CMOS sensor usually delivers finer gradation resulting from higher sensitivity, wider dynamic range, and better S/N ratio. It also has a wider depth of field allowing shallower settings for effective background blurs.

What they actually mean is that "Larger sensors gather more light, so they're more sensitive. And, because the format is larger (than other, smaller, formats), the depth of field, for the same aperture is shallower, allowing for effective background blurs.". Claiming that larger formats have "wider depth of filed" is just meaningless and wrong.

Get my test cards document, and cards for 625, 525, 720 and 1080. Thanks to Gavin Gration for hosting them.
Camera settings documents are held by Daniel Browning and at the EBU
My book, 'Circles of Confusion' is available here.
Also EBU Tech.3335 tells how to test cameras, and R.118 tells how to use the results.

You're right Alan. "wider depth of filed" is just meaningless and wrong. :D :D :D

Sorree ! Couldn't resist. :rolleyes:
