Black and white images and how to generate them
Duh! Simple right! Well, kind but no.
To my understanding, there are two fundamental ways to get a black and while image from a bayor sensor.
The first way is to desaturate the image 'mathematically', basically taking a colour image and removing the chroma.
The second way is to only process one channel from an RGB video signal. Sort of going backwards in the de-bayor process.
Both of these methods do have a different effect.
Over time i will add some test images below for reference.
