Optical zoom capability
The iPhone 7 Plus features a dual-camera system that includes an optical zoom capability. This allows users to zoom in on subjects without compromising image quality, as optical zoom physically adjusts the lens to magnify the image. The primary advantage of optical zoom over digital zoom, which simply enlarges pixels, is that it maintains sharpness and clarity even when zooming in. With the dual cameras working together, the iPhone 7 Plus provides users with enhanced zoom capabilities for capturing detailed and crisp images.
Bokeh effect for portraits
The dual-camera system on the iPhone 7 allows for the creation of a stunning bokeh effect in portrait mode. Bokeh refers to the aesthetic quality of the out-of-focus areas in a photograph, and it can greatly enhance the visual appeal of portrait shots. With the dual cameras working together, the iPhone 7 is able to create a depth map of the scene, distinguishing between the subject and the background. This information is then used to blur the background, creating a smooth and creamy bokeh effect that makes the subject stand out.
How it works:
The primary camera captures the image of the subject while the secondary camera measures the distance between the subject and the background. Using this data, the iPhone 7 software then applies a blur effect to the background, simulating the shallow depth of field typically achieved with DSLR cameras and high-end lenses.
