Final answer:
The statement is false; the rule of thirds involves dividing the image into thirds both horizontally and vertically to create nine parts, not a 4 x 4 grid.
Step-by-step explanation:
The statement about the rule of thirds involving splitting your image into a 4 x 4 grid is false. The rule of thirds is a principle of composition in photography and visual arts where an image is divided into thirds, both horizontally and vertically, using two equally-spaced horizontal lines and two equally-spaced vertical lines. This creates a total of nine parts. The important elements of the composition should be placed along these lines or at their intersections. Practice of the rule of thirds can be aided by using a digital camera's grid overlay setting, if available, to help position subjects according to this compositional rule.
