The new Pixel 4a supports Live HDR+ and Dual Exposure, features first introduced with the Pixel 4 (note that these won’t be backported to older devices). The tech giant published a detailed blog post explaining how the two features work.

First, what is Live HDR+? It shows a real time preview of what the final HDR+ photo will look like. Note that this is just a preview derived using a different algorithm. The real HDR+ takes 3-15 underexposed photos (to reduce noise), aligns them and merges them.

After the merge, tone mapping is applied to produce the final photo where details in both highlights and shadows are visible. The phone computes a 2D histogram to achieve that, which is interesting to see.

However, current mobile chipsets don’t have the computational power to do that 30 times per second. Instead, a dash of AI is used. The image is sliced into small tiles and the AI predicts the tone mapping for each of them. Then every pixel on the viewfinder is computed as a combination of the tone maps from the nearest tiles.

Here’s a comparison between the predicted image and the actual HDR+ result. It doesn't get it quite right, but it looks pretty close (especially since you'll be viewing this on the phone's screen).

Balancing highlights and shadows is done automatically by HDR+. The Dual Exposure sliders give you manual control over the process, so you can get the desired look for your photo in camera. Traditionally, this is something you would do afterwards by processing the RAW file.
