The document discusses various photographic design elements including focus, depth of field, movement, timing, optics, exposure, flare, glare, and silhouettes. It explains that focus draws the viewer's attention and selective focus emphasizes a specific area. Movement can be used to create motion blur. Timing is important to capture decisive moments. Focal length, lens type, and tilt affect the geometry and perspective of an image. Exposure controls contrast and where the eye is drawn. Flare and glare happen when light is reflected in different ways. Silhouettes require backlighting to render the subject in shadow.
