BOKEH
Now this isn’t really a compositional technique, but I feel it fits best here as it is very much about the aesthetics of an image. Bokeh is, in simple terms, the out of focus areas of an image. Those that fall out of the sharp areas defined by the aperture drift into a blur, and using this can be fantastic to focus attention on subjects or areas of a frame. For the best Bokeh, you will want to work at a wide open aperture (f2.8-f5.6) being eye level with your subject. For the cleanest looking backgrounds, you’ll want the area behind your main subject to be at least three times the distance between you and your subject for the optimum blur. By also lowering your position and using foliage between yourself and the subject you can subsequently add blur into the foreground, something that is especially useful if you want to hide certain elements of the image, or have a simple minimalist composition. Using the above rules, try them out with different subjects and always keep them in the back of your mind when shooting. With time composing, using the rule of third with three elements, will become second nature, leading you on to try more daring and interesting compositions within your images.
