Keep Your Smile Natural
Don't say "cheese," which usually conjures an artificial smile. Instead, ask the photographer to throw out an unexpected word, like "money." This will usually elicit a genuine laugh, and your expression won't look forced. "I always think of something funny, like my disastrous attempts at cooking, to achieve a natural smile," says Dupont. "If you're self-conscious or critical of your smile, practicing before a photo shoot might be helpful, too."
