The concept of lines is one of the first concepts we learn about in school (and in life). Whether it’s drawing a line, or walking in a straight line, or in math, most of us have been working with lines all our lives. Technically, a line has negligible width and depth, and infinite length, whereas a line segment has two fixed endpoints, and a ray has one fixed endpoint and an infinite length in one direction.
Mathematical semantics aside, lines appear naturally in life and nature. Buildings have straight line sides (for the most part), plants often grow in lines, people naturally form lines when waiting or when walking, and lines are even formed by erosion.
Not all lines have to be straight, they can be bent or ragged, but generally they will still provide a great concept in photography:
