Other alternatives which show promise in small-scale trials include acupuncture and light therapy. A study of 27 depressed mothers-to-be in the Journal of Clinical Psychiatry in April found that after five weeks of full- spectrum light therapy, of the type given to people with seasonal affective disorder, 13 of the women had at least a 50 per cent improvement in their symptoms and 11 were no longer depressed.

Setting up a Still Life
Lighting is also important. If you want dramatic lighting, you can choose to set up near a window for natural light, or create your own dramatic lighting with the use of lamps and spotlights. Spotlights are especially good for glass or shiny objects as they will “twinkle” in bright light. Spotlights can also cast unwanted shadows, so be careful about placement.

What is the visible light spectrum and who is it visible to?
