Desaturated image

What is lost when an image is desaturated is all the colour information. What is left is simply luminance, or light & dark aspect of the image. What is not present , as would be the case in film image is the relationship between red, green& blue translated to the greyscale.

Photography should not be about taking images, it should be about being taken by them, It should be about allowing yourself to be completely consumed by the decisive moment that will pull you through the lens & the  image is captured along the way.
