There are many challenges to being a true photographer. Lighting is one that can make an image shine and give it 3 dimensionality. When captured poorly the image can look average and flat, there are no layers and you feel nothing. There will be no breath, no life in the photograph and people will find that they feel indifferent when looking at it. Effective lighting is when you see catch lights in the eyes, highlights in the hair, contrast within the composition, and reflections or something to create depth. It this was easy to accomplish we would all be professional photographers.
