I find black and white photography really effective. The absence of colour creates the impression of a moment frozen in time. The mood and atmosphere encourages the viewer to reflect and search for a greater meaning.
Personally I feel black and white imagery looks really professional. I love the photograph of the children climbing the wall. The strong contrast of the railing against the sky and the composition and perspective leading your eye deep into the photograph.
Effective Black and White photography is a technique I would like to develop.
