Maybe it’s just me, but there’s something to be said about shadows. Depending on the lighting, background, framing, etc. they have the capacity to make powerful images and convey many different moods.
Dark background and out of focus subject, the photo can be scary or mysterious. Field of flowers and bright sunshine and the same shadow is suddenly calming and cheerful.
Being a photog means paying attention to the little things. Shadows are something that people see every day with normal objects, but do they really pay attention?
A photographer’s job is to show people something they don’t normally notice. Shadows are a nice way to do this.
So grab your camera and try examining shadows at different angles! You may rediscover an old place or object or person in a new light.
