WebBokeh simulator and depth of field calculator. This application interactively calculates the camera depth of field and background blur and visually simulates it on a photo together with different types of lens blur (bokeh) for any lens, camera and distance combination. Activating the help mode shows descriptions of the interface elements. WebShallow depth of field is achieved by shooting photographs with a low f-number or f-stop — from 1.4 to about 5.6 — to let in more light. This puts your plane of focus between a few inches and a few feet. Depending on your subject and area of focus point, you can blur the foreground or background of your image.
