![]() (If there isn’t much detail in the background, the effect of the depth blur will be less pronounced. Here’s how to use Photoshop’s neural filters to quickly and easily add background blur to images that would benefit from a shallower depth of field for less visual distraction from a busy background.įirst, choose an image with a well-defined point of interest- a portrait for instance-and open it in Photoshop. (You can also use neural filters for other magical editing applications, including skin smoothing and expression changes and even the repositioning image elements in ways heretofore impossible without human intervention.) These neural filters use machine learning to evaluate millions of images and distinguish, among other things, from foreground elements and backgrounds. This capability is part of Photoshop’s major update for 2021 that added neural filters to the image editing application. This means a photographer who shot an image at ƒ/8 can convert that file to have the look of shallow depth of field that comes with an image captured at ƒ/2. In practice, it means that Adobe has figured out how to help us photographers make artificial depth of field adjustments post capture to help put the center of attention on the subject. And while smartphones use multiple lenses to approximate the same sort of binocular vision as our eyes, the engineers at Adobe have built algorithms that can infer those qualities in any camera image-even ones from those old-fashioned cameras that produce files with just one lens. It then uses that information to apply smart filters that create the artificial appearance of shallow depth of field by blurring the background. The modern smartphone uses its multiple lenses to quickly create a depth map of a scene and distinguish subject from background.
