Product photography is another catch all category. It really includes everything from food to cars, but in reality it is what you put on your website, posters, flyers or in a magazine to sell product. It is a photographers bread and butter, but lets give it a bit of respect and make sure it is done right. Even a pack of butter on a white background needs to be sharp, clean and clear. This really is just information, but it can be given attitude and style and lifted above the rest. Advertising 101 - 'point of difference'.
