While I've heavily been a black and white shooter for a while, there's been a slight tugging to colour. I truly enjoy the tones and the mood that black and white images have. It forces you to look beyond shades of red, green, blue and straight into the geometry and also straight to the people's expressions and actions in an image.
The truth is though, I enjoy colour too but... I think I'm really picky about it. It HAS to be right. It's so easy for us to just explode images with colour without thought or to get it wrong or inaccurate. Colours play an integral role in a photographic image and, believe it or not, also in black and white imagery.
Film for me gets colours right.
(And, with some tweaking, digital images with film presets).
