How about trying out food photography, styled as if for an advert, poster or menu? This was my get=pushed challenge by Sally Ings. Well I meant to photo graphed the Layered Pizza Dip But it is a heated dip and I was late preparing it to my nieces next door and hurried it - forgetting to photograph. So I got my Great grand niece to pose eating it. A person smiling eating the product sells.
