A hobby, a passion, a meditation, a craft, an art:
however you look at it, photography is a wonderful way to capture light, and to share it with others.
Of course, there's much more to capture, than light: shapes, colours, textures, emotions, motion, mood, information, nature, memories, grandeur, simplicity: whatever you can see (or whatever is present waiting for you to look at it), an image captured in a camera can bring the experience into your own soul, ready to express as a photo to others.
