There's something beautiful about black and white images. They cause us to look at photos in a different way. They can convey beauty that colored images cannot.
Their graininess gives the picture a raw authenticity, rather than being merely a poorly lit subject.
They make us more aware of the distinct angles and shapes of the subject.
They can show extreme contrasts of light and dark that would otherwise be unpleasant in color.
Their blurred subjects look like an art technique, rather than an error of slow shutter speed.
The shades of black, grey, and white are like the blue, green, and brown hues of the sea--they are boring by themselves, but put together they create a depth that attracts the eye. I feel that by taking the color away, which our eyes are naturally drawn to, I'm forced to look deeper for what makes that photo artistic. There's lots of room for creativity in black and white images, and that's why I love them so much.
