I absolutely love food photography!! Would I buy a cookbook with out it? Probably not, unless it came high HIGHLY recommended. Photos of Food just add so much charisma and substance to cook books and Magazines. They provide such an emotion that comes with eating food. A good photograph of food should provoke all of the senory senses. You should beable to taste, hear, smell, see, feel the food.
I wish so badly I was better at food photography and styling. But I have found these links helpful Food Photography.
