Abstract: A picture composition guidance system for guiding a user to take pictures with quality picture compositions includes a horizon guide having an upper horizontal line and a lower horizontal line, a diagonal guide having a pair of diagonal lines, and a strong points guide having a pair of upper markers, a pair of lower markers, and a center marker. The horizon guide, the diagonal guide, and the strong points guide are superimposed on a viewfinder for a camera such that the upper horizontal line and the lower horizontal line demarcate the view finder substantially in thirds. Further, the pair of diagonal lines intersect on the lower horizontal line while the pair of upper markers are positioned on the upper horizontal line, the pair of lower markers are positioned on the lower horizontal line, and the center marker is positioned substantially in the center of the viewfinder.
