Depth of Field (DOF): The distance between the closest and farthest objects in an image captured by a camera; a narrow DOF has fewer objects in focus, whereas a large depth of field can have an entire image in focus.
Focus: Adjusting the camera lens manually or automatically to get maximum detail and sharpness.
Saturation: intensity of color
Rule of thirds: a type of off-center composition in which an image is divided evenly into thirds, both horizontally and vertically, and the subject of the image is placed at an intersection of two dividing lines in order to draw the viewer’s eye to the main subject
