Guiding lines in photographic composition: straight lines, curves and line of sight

First determine the role of lines in the picture

When photographing buildings or other strongly linear subjects, observe how the lines lead the eye across the frame. Leading lines can sometimes take the eye out of the frame, so decide what you want the viewer to see before deciding which lines to keep. 〔G-LL-01〕

The line can be the subject or point to the focus

Roads, building edges, or other obvious lines can directly become the main subject of the picture, or they can lead the viewer to a focal area in the photo. Neither usage requires that the lines lead to separate figures or objects. 〔G-LL-02〕

Incorporate curves into the composition for observation

In addition to straight lines, look for curves on stairs, roads, or other scenes. The curve itself can become the subject, and it can also allow the line of sight to move along the picture or turn to other subjects; its role must be judged based on the specific picture. 〔G-LL-03〕

Use test shots to compare, rather than applying iron rules

You can change the shooting position or framing range and compare where the lines draw attention. Composition suggestions are only a starting point; if deviating from common practices better suits your pictorial goals, leave that option open. 〔G-LL-04〕
