Variable factors in Digital Cameras that effect quality
Variable factors in Digital Cameras that effect quality.
In addition to build quality, and ergonomics, there are many subtle factors that make these cameras different from one another in terms of how they produce the final image.
- A sensors dynamic range, anti-blooming and highlight control, blue channel response, and physics associated with sensor (e.g. fillfactor)
-Demosaicing algorithm and interperlation
-Noise processing (particuarly with CMOS sensors)
-Image capture method (eg. clocked Kodak 14n/SLRn/SLRc routine for long exposure)
-Image processing (eg. Canon DIGIC II/ LSI Venus Engine II just to name a few)
-Size of pixels
-The array of microlenses and filters that lie on top of the actual sensor
-AA filter (if installed) and strength
-Arangment of sensor (e.g. Bayer pattern, CYMG, Fujifilm's SuperCCD/Fujifilm SuperCCD SR / Sony ClearVid CMOS sensor/ Nikon D1x's double horizontal resolution CCD (rectangular pixels))
-Sensor technology (CMOS, CCD, JFET LBCAST sensor, MOS, Foveon X3 sensor, Live MOS' sensor, Canon CMOS (modified for astrophotography) )
-Raw software (E.g. H2's Digital APO Correction (DAC))
-And lets not forget the lens used ( e.g. Digital Optimized lens design as detailed in Olympus 4/3rds whitesheet)
