Elements of art and principles of design in photography

Line is a mark with greater length than width. Lines can be horizontal, vertical, or diagonal; straight or curved; thick or thin.

Shape is a closed line. Shapes can be geometric, like squares and circles; or organic, like free-form or natural shapes. Shapes are flat and can express length and width.

Forms are three-dimensional shapes expressing length, width, and depth. Balls, cylinders, boxes, and pyramids are forms.

Space is the area between and around objects.

Color is light reflected off of objects. Color has three main characteristics: hue (the name of the color, such as red, green, blue, etc.),

Texture is the surface quality that can be seen and felt. Textures can be rough or smooth, soft or hard. Textures.

PRINCIPLES OF DESING
Balance is the distribution of the visual weight of objects, colors, texture, and space.  
Emphasis is the part of the design that catches the viewer’s attention.

Movement is the path the viewer’s eye takes through the work of art, often to focal areas. Such movement can be directed along lines, edges, shape, and color within the work of art.
Pattern is the repeating of an object or symbol all over the work of art.

Rhythm is created when one or more elements of design are used repeatedly to create a feeling of organized movement.



Unity is the feeling of harmony between all parts of the work of art, which creates a sense of completeness.
