I’ve written before about how I think most B&W pictures would probably also work as colour but that the reverse is rarely also true. The inherent interest of an image will always remain regardless of the saturation, but B&W composition requires the interplay between light and dark to work in a way that isn’t always required for a colour composition to also be successful.
I love B&W, but I am more aware now than I’ve ever been that my talent, such as there is any, is for colour rather than monochrome photographer; I always find myself composing in colour and then deciding after the fact that a given image would perhaps work well, or even better in B&W. This is luck and serendipity rather than talent; I am certain that exceptional B&W photographers compose in monochrome and know how that composition will work as such before they take it.
For now, I am happy to see the world and the people in it in colour. I will always enjoy the serendipity of a good B&W composition, but I won’t try to maintain any pretence about being talented in this area!
