B/W DSLR modification study

Generally color image sensor is arranged as the pattern of RGBG 2×2 pixels color filter array, It can make the color images through 1 shot exposure but the large amount of light were blocked by color filters on CMOS and color processing algorithm produce false colors. The optical low pass filter to prevent false color on color image sensor makes lower resolutions to output image.
In low light photography field B/W sensor with high QE and low noise is most valid device for higher resolution image. Read more
