It has been said to me that I lately take alot of B&W photos and that it reflects a very sad/depressed mood I might actually be in. I may be sad sometimes, true.
But B&W or color photography has absolutely nothing to do with my mood, some lights have a better rendering in B&W than they have in color. It's purely a matter of aesthetic . Period.
I'll end this post with this quote :
"Viewing a color photography is like seeing a movie, while viewing a black and white photography is like reading the book."
