一般的な商品写真では、影なしで撮った方がいいですが、食べ物の場合には影ありのほうが普通です。皿、カップの前に影を作ってください − 照明は商品の後ろとちょっと左の方に置いて下さい。 Normally you should be aiming to remove almost all shadows from a product shot, and instead having no single evident light source. However for the case of food, you need to ensure that a shadow exists, and more partiularly that the shadow falls in front of the item, towards the camera. So you need to position your main light source behind and slightly to the left of an item.
