It doesn't offer much in the way of configuration. In the long term, + it's going to be replaced. In the short term, there are other apps available providing + more capabilities and better support for taking advantage of the hardware.</p> + + <p>The Pixel 2 and Pixel 3 (but not the Pixel 3a) have a Pixel Visual Core providing + a hardware-based implementation of HDR+. HDR+ captures many images and intelligently + merges data across them, taking into account motion, etc. It substantially improves + the quality of images, especially in low light. This is used transparently for third + party apps that are compatible with it, and there isn't an explicit switch to turn it + on or off for most of them. An example of a compatible app is Open Camera's default + configuration, or Open Camera with the Camera 2 API and other settings (including the + the various knobs / toggles outside of the settings menu) left alone. In general, HDR+ + will work transparently in most apps as long as they keep things simple and use a good + minimalist approach to taking pictures. It should work transparently in most messaging + apps, etc. with internal support for taking pictures.</p> + + <p>In addition to supporting HDR+ via the Pixel Visual Core, or similar features on + other devices with the same constraints, Open Camera offers advanced configuration and + various advanced features. Make sure to enable the Camera 2 API in the settings, which + should be the default, but the app doesn't have a great user interface / user + experience. You probably don't want to use the traditional HDR feature in the app. + That's not HDR+, but rather captures 3 images and merges them in a way that isn't at + all intelligent and causes a lot of blur and distortion. The HDR+ implementation can + actually benefit from the camera not being completely steady as it's smart enough to + match up the picture and it provides it with more data vs. a traditional HDR + implementation where it essentially doesn't work without a tripod and is not really at + all useful on a phone unless you actually have that for it.</p> </div> <footer> <a href="/"><img src="https://grapheneos.org/logo.png" width="512" height="512" alt=""/>GrapheneOS</a> |
