Entitled "The Backdrop," the video features the Depth Control in action on a shot of a woman taken on a busy street with a lot going on in the background.
Depth Control is used to blur the background out, putting the focus on the woman in the picture.
Introduced on Apple's newest iPhones, Depth Control is a Portrait Mode feature. Once you capture a Portrait Mode image, you can use the Depth Control slider to change the amount of blur in the background.
Apple also recently shared a new video on the Smart HDR feature in the new iPhones. Smart HDR is an automatic feature designed to bring out more detail in highlights and lowlights in iPhone photos.
The video was created as a behind-the-scenes look at the techniques used by Jia Zhangke in his recent short film captured to celebrate Chinese New Year.
