Composition concerns arranging elements in an image with consideration for several factors to create a harmonious whole that conveys the intended message. The frame determines what is seen, and horizontal or vertical formats should be chosen based on the subject. Important compositional techniques include filling the frame, adjusting the vantage point, using the rule of thirds, and incorporating lines, symmetry, patterns, and a vanishing point to guide the viewer's eye. Mentorship can help less experienced photographers develop their technique, philosophy, style, and chosen subject matter. Examples of influential photographers discussed are Andreas Gursky, known for large format architecture photos, and Hiroshi Sugimoto, whose long exposure works explore themes of time and transience.
