![]() The look and shape of the bokeh are also dictated by the lens’s optical design. To achieve a bokeh most associated with the word, your aperture should be an F/2.8 at its narrowest point. This means that at 75mm, the lens’s widest point is F/4, but as you move closer to 300mm, the aperture will narrow to F/5.6. This is denoted in the following example: Canon 75-300mm F/4-5.6. Some lenses have a variable aperture, which means that the width of the aperture changes throughout the lens’s zoom. All lenses will have an F/-number- after the lens focal length (the -number- MM).įor example, a Canon 50mm F/1.8 lens. By looking at the lens name, you can see what aperture your lens can go at its widest point. Some lenses have apertures that can go super wide, such as the legendary F/0.95, but others are more narrow, such as F/5.6. How wide your aperture can go is limited by your lens. The smaller the aperture, the less light it lets in and the deeper the depth of field. The wider the aperture, the more light it lets in, and the shallower the depth of field. The larger the number, the narrower your aperture. ![]() The smaller the number, the wider your aperture. ![]() Fun fact, “bokeh” is a Japanese word that directly translates to “blur”! What Causes Bokeh? When a depth of field is deep, the subject, the foreground, and the background are in focus.īokeh is the characteristic and quality of the blur produced by shallow depths of field. ![]() When a depth of field is shallow, that tends to mean that just the subject is in focus, and the rest of the image blurs away. Depth of field refers to how much of an image is in focus. To explain what bokeh is, we must first define the depth of field. So what is this “bokeh” we are talking about? What is Bokeh? One way to achieve this goal is to create images that the average person cannot- such as shallow depth of field! Shallow depths of field produce a bokeh, a photographic characteristic only proper cameras can do. To learn more about Focos or pick up the free app for yourself, head over to the Focos website or go straight to the iTunes App Store.As photographers, we aim to capture eye-catching images that captivate the viewer and leave a lasting impression in their minds. The results should ostensibly look better than what Apple is generating with its own Camera app, but at the very least they'll be more customizable so you can find a more appropriate effect for every photo. And since it's already capturing 3D data, the app allows you to access that data and apply filters based on depth. But if you're not a fan of the fake bokeh Apple's standard camera app generates, you might want to check out a free new app called Focos.Ĭreated by the same indie developer behind the apps Colorburn and MaxCurve, Focos takes your iPhone 7 Plus, 8 Plus or X's Portrait Mode shots and makes them look more 'professional' by adding more realistic and customizable bokeh effects.įocos allows you to pick custom bokeh 'shapes', generate more professional-looking bokeh by selecting options like 'creamy' or 'swirly', import your current Portrait Mode photos and re-edit the background, and re-focus Portrait Mode photos after the fact. Apple's 'Portrait Mode' on the company's dual-camera iPhones is a cool feature that produces some neat photos.
