Stockphoto Tip: Stock photography sites advise their photographers to create people images that have clear backgrounds so there is more flexibility for the buyer. For example, you really like the expression on the face of a particular man in two different camera shots. But, the first man is shown with a white background and the second is of a man driving a car. The second option limits your usage. And remember, since you are paying for the people images, you want it to be as versatile as possible.
