Portrait Photography tips for Beginners

If one person is a bit stale two people are perfect

Whenever I m shooting a subject that gets a bit camera shy and won t give me much of an expression, I always try to let the person interact with someone different. For example, trying to get kids to have fun and smile will be tough without a parent being in the studio too. This technique works the same with adults. If your subject looks a bit stale, wait until they talk with someone else to capture the best expressions.
