Controlling the Background @ohnorok- Creative aperture control allows you to remove the background by blurring it out, which directs the focus to the subject. Using a shallow depth of field allows selective focus, which is used to highlight detail in a small area of a scene. Conversely, a large depth of field can bring the background into the picture, when needed. A Bit About Bokeh 20 | PicsArt Monthly @shamzrapz @kate-cat You have probably heard this word thrown around a lot, but what is bokeh? How do you even say it? While the second question is a topic of endless (and fruitless) debate, most people agree that bokeh is the way the lens renders out-of-focus blur. This is most obvious in points of light; when defocused, the haze they create takes the shape of the aperture. Sometimes it is beautifully round, sometimes it's octagonal, and can be more like a pentagon. Conventional opinion believes that the rounder the aperture, the better the bokeh.
