Abstract: A reliable and repeatable accuracy of focus measurement device to measure the focus accuracy of cameras that employ a different light path between the lens and the focusing sensor and between the lens and the film or image sensor. The measurement device includes a frame having a substantially planar front face with a focusing target located thereon, and at least one depth-of-field ruler coupled to the frame with a transverse axis falling within a front face plane and a long axis that is angularly adjustable with respect to the front face plane.

Abstract: A method is disclosed for recording ambient lighting conditions from a reference card using a digital camera to record a spectral response of the reference card to enable a digital photograph to be white balanced. The method can include the operation of providing a substrate to carry a reference surface. A highly polished material can be applied over the substrate to form a reference card having a highly polished surface. The reference card can be photographed with the digital camera to record the ambient lighting conditions.
