As I have been learning to enhance photos, I have also been learning why black and white photos are perennially popular. It is a nice change of perspective to get away from working with color and work on a more sculptural and/or textural image.
Black and white also has different moods than color, ranging from cool and spare to dramatic and mysterious, depending on your choices while composing it.
I was able to make this photo dark and dramatic by heightening the black and white contrast. However, it was lacking interest until I decided to experiment with Picasa’s neon effect. The red edging was just what the photo needed to really pop. It’s hard to believe that the enhanced photo came from the original photo below.
