| Center of interest | A single element of the photo to which all the other elements of the picture will relate. |
| Exclusion | Selectively framing to eliminate unwanted elements in the photo; sometimes referred to as “cropping in the camera”. |

| Leading lines | Pictorial elements that draw the viewer’s eye from one area of the photo to another. |
| Pattern- | A compositional element made by multiple objects. It may consist of repetition of identical shapes, or may have elements alternating or varying in either shape or size. |
| Rhythm | A compositional element that consists of repeated shapes or lines that move the eye through the frame. |
| Rule of thirds | A compositional device that divides the frames into thirds, both horizontally and vertically. |
| Viewpoint | Descriptive term for the distance and angle from which the camera (and eventually, the viewer) would see the subject. |
