Check out the book trailer for Picture Day Perfection by Deborah Diesen, illustrated by Dan Santat (Abrams, 2013). From the promotional copy:
It's picture day, and the boy at the center of this charming picture book wants to make sure his picture is perfect.
It seems as though everything's going wrong for him—he has bedhead, a stained shirt, and a big scowl on his face.
But when he goes up for his picture, he thinks about his terrible appearance, and he smiles—because he secretly wants his picture to be the worst ever taken!
But just as he smiles, the photo is snapped and his plan is ruined—the photo looks great.
