At the shorter focal length (24mm), the depth-of-field is greater, with the elements in the background in focus. The examples below were shot at different focal lengths, but with the same f-number (f/11), and the shooting distance was adjusted so that the pillars appear to be the same size. Let’s take a closer look at each of the factors that affect deep focus.
In other words, the easiest way to ensure you achieve deep focus is to use a wide angle lens, set it at the smallest aperture, position your camera as far away from the subject as possible, and make sure that there is very little depth in your image.ĭeep focus tip: Using a narrow aperture slows down your shutter speed, which makes images taken in dim or dark places more prone to camera shake. The nearer the camera to the subject, the shallower the depth-of-field. Shooting distance: The further the camera from the subject, the larger the depth-of-field. The more depth in an image, the harder it is to achieve deep focus. The flatter the image (less distance between the elements), the easier it is to achieve deep focus. When you photograph, it is important not just to have a good understanding of the concept of “ depth-of-field” (the area of an image that appears in focus), but also good control of these 4 factors.įocal length: Depth-of-field is greater at short focal lengths, and shallower at longer focal lengths.Īperture: Depth-of-field is greater at smaller apertures, and shallower at larger apertures.ĭepth: This refers to the distance between foreground, medium ground and background elements. There are 4 factors in achieving deep focus: Focal length, aperture, depth and shooting distance. You can call it a technique that is the opposite to creating bokeh. “Deep focus” refers to a state where all elements in an image are in focus.
How about trying them in your next photo shoot? (Reported by Tomoko Suzuki) Here, we learn about 4 factors that affect deep focus. Deep focus, where all elements in an image are in focus, is a technique that is often used in landscape photography and street photography.
