    Abstract: Apparatuses and methods for producing improved photographs suitable for measuring teeth whiteness with a handheld camera using a camera jig are provided. The camera jig includes a base that contacts a surface. The camera jig also includes a light shield made from a tubular structure defining an interior cavity. The camera jig further includes a slot in the tubular structure that supports the handheld camera at a predetermined distance from a target, which may be teeth of a user. The slot aligns a lens of the handheld camera with the target. Further, the light shield blocks substantially all ambient light, other than light of a light source of the handheld camera, from the target as it is photographed.
