Night Sight, introduced with the Pixel 3, returned on the Pixel 4 and was further refined. This feature allowed the Pixel 4 to capture surprisingly bright and detailed images in extremely low light conditions, often rivaling dedicated cameras. The process involved the phone capturing a series of long exposures over several seconds, analyzing the data, and then combining it to produce a remarkably clear photograph.
The Pixel 4 extended this capability to astrophotography. When pointed at the night sky, the device could capture stunning images of stars and even the Milky Way. By keeping the shutter open for extended periods and employing sophisticated noise reduction and detail enhancement algorithms, the Pixel 4 could reveal celestial details that would otherwise be invisible to the naked eye. It transformed the smartphone into a gateway to the cosmos, making astronomical photography accessible to a broader audience.
Portrait Mode Enhancements
Portrait Mode on the Pixel 4 continued to refine its ability to create photos with a blurred background (bokeh). The dual-lens system contributed to more accurate depth mapping, leading to more natural-looking subject segmentation and a smoother transition between the in-focus subject and the blurred background. The algorithm understood the spatial relationships between objects and applied a more nuanced bokeh effect.
Continued Excellence in HDR+ and White Balance
Google’s HDR+ (High Dynamic Range) processing remained a cornerstone of the Pixel camera. This technology captured a burst of images at different exposures and combined them to produce a single image with a wider dynamic range, preserving detail in both the highlights and shadows. The Pixel 4 continued to excel in this regard, producing well-balanced and natural-looking images in challenging lighting. Similarly, its automatic white balance was consistently accurate, ensuring that colors were rendered faithfully.
