The photo is following the rule of thirds and the depth of field is well placed. In the photo above, the lighting and shot are excellent. A photo with bad bokeh distracts the eye away from the central subject. Bokeh aims to highlight a subject while still emphasizing a warm and enhanced background. When bad bokeh occurs it doesn't mean the photo is "bad", it just doesn't qualify under the standards of proper bokeh use. Your eye should be drawn to the subject, and the background pushes you there even more. In good bokeh, the subject is further highlighted by a warm and welcoming background. Bad bokeh simply requires the wrong movements at the wrong time. In 1977, Mike Johnston officially named this skill as "bokeh" and it has evolved from there ever since. By letting in plenty of light and focusing the subject in a shallow depth, a skilled photographer could make a subject stand out even more through a soft and composed background. By doubling lenses, widening angles and rendering out of focus points of light favorably, spherical aberrations were no longer to be abhorred. The Petzal lens and others began to use aberrations in their favor. As witnessed here, aberrations make points of light take on unique characteristics when refracted through a camera lens. Fast cameras quickly capture the light with faster aperture settings and wide lens, creating clearer and cripser photos. When an image is completely blurry, the subject or camera moved, shifting the light refractions leading to the blur. Aberrations in photography simply refer to the blurry or distorted parts of a photo, generally seen to be in poor form either from a crap lens or terrible photographer. That was Petzval at its finest.Īs mentioned above, spherical aberrations are a photographer's worst nightmare. Imagine comparing a Monet to that one time your grandma tried to take a selfie. Creating a double lens system meant the background or anywhere outside the depth of field no longer appeared quite so blurry and instead appeared artistically driven. While this sounds like a bit of mumbo jumbo to the average person (read:me), the science was ground-breaking. The camera contained a double lens that corrected for spherical aberrations and with a quicker f-number (f-stop), the subject appeared sharper while their background took on a swirly, softness. Now this is where we throw on our lab coats and go back to 1840 when Joseph Petzval created the Petzal lens and bokeh began to take shape as an identifiable, scientific idea. The Science Behind Bokeh and iPhone 7 Plus Portrait Mode However, if years of art and science are worth following, Apple's foray into the world of bokeh is worth paying plenty of attention to. But even with all this computer software being thrown around, most common users were still left wondering why bokeh was anything worth caring about. With the help of artificial intelligence and a dual camera system, Apple has created a program to mimic Bokeh using faster aperture settings and software that takes facial recognition, lighting and the depth of field into account to create an image that appears to use the traditional methods to create bokeh. Good bokeh is identifiable by a softer, diffused image that accentuates the depth of field while not sacrificing the background by simply blurring it. A variation on a Japanese word that means ‘blur’, Bokeh centers on the quality of the background as it works to emphasize the subject. Portrait mode, essentially, is using the photographic stylings of bokeh. Being the writer/know-it-all/nerd that I am, I figured the best way to figure out Portrait mode was to actually research what any of it actually meant. Except that I knew absolutely nothing about bokeh or portrait mode and the internet was still raging about the loss of the headphone jack. I finally thought I could become like my professional photography friends, taking hipster pictures of my dog staring off into the sunset. With the announcement of the iPhone 7 and 7+ from Apple, the internet became alight with discussions on the bigger storage capacity, water resistance, and Portrait Mode. They were a bit nicer but it's true, I know just about nothing when it comes to photography. When I began to ask about bokeh and Apple's new Portrait Mode for the iPhone 7 Plus, the seasoned professional photographers in my life generally answered like this: A Primer On Bokeh And iPhone 7 Plus Portrait Mode An image from Apple's keynote introducing Portrait mode for iPhone 7+.Įver wondered how to get that beautiful bokeh effect with your iPhone 7 Plus? Ever wondered what exactly "bokeh" is? For all of us out there who aren't professional photographers, join this journalist as she dives into the wonderful world of iPhone 7 Plus photography, the science and art of Bokeh, and learns how to take great iPhone 7 Plus pictures using Portrait mode.
