Portrait modes that simulate the shallow depth of field of a large sensor camera and fast lens have been around on smartphones for a long time. The Pixel 2 was the first Google phone to offer the feature. With the Pixel 2 being a single-lens camera the dual-pixel autofocus system was used to estimate the parallax and thus depth. The Pixel 3 still relied on dual-pixels but the system was improved using machine learning.

The latest Google flagship, the Pixel 4, is the first phone in the Pixel line to feature a dual-cameras. This allows for even better depth estimation by leveraging both the dual-camera and dual-pixel auto-focus system. In addition Google has also improved the appearance of the bokeh, making it more closely match that of a large sensor DSLR or mirrorless camera.
With the dual-pixel autofocus distance between the two focus pixels is very small which makes it difficult to estimate depth further away from the camera. The Pixel 4’s dual-cameras are 13 mm apart, allowing for a larger parallax and making it easier to estimate the depth of objects at a distance.
…dual-pixels provide better depth information in the occluded regions between the arm and torso, while the large baseline dual cameras provide better depth information in the background and on the ground.
Google is also still using the information collected by the dual-pixels, though, as it helps refine depth estimation around the foreground subject. In addition machine learning is used to estimate depth from both and dual cameras. A neural network first processes data from the two separately into an intermediate representation. A final depth map is then computed in a second step.
In addition to the improved depth estimation spotlights in the background are now rendered with more contrast, making for more natural looking results. This is achieved by blurring the merged raw image produced by the HDR processing and applying tone mapping.
It’s inexpensive, lightweight and will keep going for days on a single battery charge. While it’s not great for video and its wireless image transfer is slow, the D3500 is a simple and un-intimidating camera that’s a great starting point for beginners.
The D780 comes as a belated update to the well-respected D750. We’ve been impressed by what we’ve seen of what’s essentially a mirrored Z6.
Canon’s latest flagship, the EOS-1D X Mark III is a big, fast, tough DSLR that hides an impressively refined mirrorless camera within it. We’ve taken a pre-production model to a basketball game, a low light concert, and even a blacksmith shop. Find out how we think it stacks up.
We’ve been testing the Nikon Z50 extensively and found a lot to like about it. However, the camera’s biggest drawback is probably that it faces such well-established competition.
