What’s more important? Can one pick and choose between the two?
A brilliant shaft of light shot through the triangular window over head. It threw its brightness over the wall like a golden blanket. The soft sun discovered hidden lines and objects hanging amongst the shadows and jet black of the wall. As the color rushed in behind the light it warmed them too. Shimmering gold and bold reds revealed. The whole spectacle framed in its the triangle of light and color.
Shooting in each has its merits. The strong light and lines are particularly present in black and white, while the eye is drawn to the impossibly vibrant colors when shot that way. I personally think balancing color can be quiet tricky, and black and white is the easier, and maybe more elegant, medium to work with, however when done correctly one cannot deny the dynamic and animate display that takes place across a color photograph. To say one is better than the other is impossible, you can choose a film for a particular shot and even that eventually is the artist’s preference and even then sometimes they cannot: as I could not below.
