Image sensors and their patterns - opinions?
« on: August 29, 2013, 04:08:02 AM »
Despite owning the 550D, I've never really been a fan of CMOS sensors, or of the bayer sensor pattern.
3CCD has always looked juicy in my own opinion, but I have been told it can only do up to certain resolutions before alignment becomes an issue.
(Although recording all three sensors separately could then be aligned correctly in post I would imagine.)


Recently! I came across information of this "foveon X3 sensor" - https://en.wikipedia.org/wiki/Foveon_X3_sensor
And I'd like to get any opinions on it if people hold them. http://www.foveon.com/article.php?a=67

The axiom camera plans to use a CMV12000 from CMOSIS, which is a CMOS sensor with a global shutter, but it still has a bayer sensor pattern.

Which the problem with bayer is the moire.
But, ultimately with raw, if things like libraw improve, which it constantly does, moire becomes less and less a problem.

Sensors need to be responsive to frequency.  Then they could dump the bayer filter which cut out around 80% of light iirc.

Which is in a way what that foveon does.
