Could someone kindly list the points please ??
By the way, what is Color Filter array? G-R-G-B or C-Y-G-M ? What's the difference ?
1. You look for what you need in a camera.
for eg. what final output your camera is for: print? or screen (to be viewed only on the computer)
But now cameras are a min 2 megapixel and above, which is more than enough for most basic printing needs of a 4R picture, den comes the question of WHAT FUNCTION you need.
Full manual controls? Lens (how wide or how tele you need) etc..
It's quite a wide scope to talk abt the more advance camera so my question to you is "WHAT ARE YOU GONNA BE SHOOTING WITH??"
I'm sure many CSer here will reply if your a little more specific abt ur needs.
2. Colour filter array is the wat the pixels recieve colour through the lens, either Green-Red-Green-Blus or Cyan-Yellow-Green-Magenta. Tecnically, a film camera picks up light and colour at every "pixel area", but with digital, it picks up the intensity of a colour at it's pixel within the array and "GUESS" the neighbouring pixel's colour to form a picture. Reason this is done is because CCD cannot see colour. It sees only Black and white. It makes use of the colour filter array and creates a picture through channeling the light into Red Green and Blue channels. Add theses channels up and it forms a full colour picture.
Now where is there an extra Green in a RGB photo with a GRGB pixel array? That's because the human vison are more sensitive to green (or something like that LOL ;p not too exactly sure)
