still substantially weaker (especially on Linux, where it can hardly be considered a
sandbox at all) and lacks support for isolating sites from each other rather than only

<h2>Camera</h2>
<p>The Camera app included in GrapheneOS is very basic and can't take full advantage
of the hardware. 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>
