![]() The app made the list because of the wide range of bokeh styles and colors. This app comes with existing bokeh effects that are overlaid onto an image. Unlike what the name suggests, Real Bokeh does not add a 'real' bokeh to your images, though one could quibble over the precise definition of free. Unlike some of the other apps on this list, the Bokeh Lens app comes with a fee, though it is small at only 99 cents. This gives it a more natural look, though one that still isn't quite on par with an actual DSLR or similar camera. ![]() The app isn't the easiest to use, but once you get the hang of it, you'll be able to produce decent photos.īokeh Lens is an app for iOS that works by converting an image's actual background into a blurry bokeh rather than overlaying bokeh effects onto the image. If you phone doesn't offer a bokeh effect, though, give the following apps a try:ĪfterFocus is an app available for both iOS and Android that enables users to select the foreground and background in their digital photos, apply a shallow depth-of-field effect, apply a bokeh effect, and choose the shape of the bokeh. If it has one, it's possible that effect will be higher quality than something you'd get from a random app store effect. In this shot, taken in my office, the cat is literally 5-6 feet away from the iPhone, but it is still significantly blurred.The first thing to do is check your phone's native camera app for a bokeh feature. In both cases, the thing I’ve focused on is literally about a foot away from the camera, while everything in the background is around 100 feet away or more.īut you can get significant background blurring even with much less space to play with. That’s what I did in the photo at the top of this piece, and here’s another example. There is, however, an exception: when you focus on something very close to the camera. So even at f/1.8, pretty much the whole image is focus. Yes, the iPhone one is bigger than many, but it’s still tiny compared to a full-size camera. On an iPhone, however, normally almost everything is in focus despite that f/1.8 lens, so what gives? The answer is the second factor: sensor size.įor any given aperture, the larger the sensor, the shallower the depth of field. A full-format DSLR camera has a large sensor, so permits shallow depth of field. Compact cameras have smaller, but still sizeable sensors, so can still achieve shallow focus, just not to the same degree. On a DSLR, that would get you a beautifully-blurred background, like this photo I took in Cambodia with a whole bunch of people stood just 10 feet or so behind the child. But the iPhone 7 has a wide-aperture lens, at f/1.8. Smartphones don’t let you change the aperture. ![]() Shoot on a conventional camera with a wide aperture and you’ll blur the background. Also, the wider the aperture the shallower the depth of field. ![]() The bigger the hole, the wider the aperture – and the more light the lens lets in. That’s known as the aperture, and a traditional lens uses metal blades like this: The other way is to change the size of the hole through which the light passes. One way to do this is to adjust the shutter speed – have the shutter open for a shorter or longer amount of time. To correctly expose a photograph, a camera needs to let in the right amount of light. The answer to that question is down to two factors: ![]() So, why does the 7 Plus need to create fake shallow depth of field anyway? Why does shallow depth of field tend to be found only in expensive cameras, not cheaper ones, and not smartphones? But if you’re interested in understanding how this whole shallow depth of field thing works, read on. If you’re not interested in the ‘why’ but just want to get to the ‘how,’ then skip down to the sentence above the leaf photo. But all iPhones are capable of generating optical shallow depth of field in very limited circumstances, and it’s actually really easy to do so … Only the iPhone 7 Plus, with its dual-camera system, has the ability to generate artificial shallow depth of field, an effect activated in yesterday’s beta. But, thanks to Apple, the world is using one term to refer to the other, so I gave in where the headline was concerned. I did cringe slightly as I wrote that headline, as it would be more correctly stated as ‘How to get shallow depth of field’ – bokeh being the particular appearance of the out-of-focus areas. Not the most artistic of photos, but illustrates my point … ![]()
