This release does not have a Play Store Description, so we grabbed one from version 8.2.300.368894857.16:

Never miss a moment with Google Camera, and take fantastic pictures and videos using features such as Portrait, Night Sight, and the video stabilization modes.

Features
• HDR+ with dual exposure controls - Take pictures using HDR+ to capture fantastic photos, especially in low-light or backlit scenes.
• Night Sight - You’ll never want to use your flash again. Night Sight brings out all the best details and colors that get lost in the dark. You can even take photos of the Milky Way!
• Super Res Zoom - Super Res Zoom keeps your pictures sharp when you zoom in—without the blur.
• Top Shot - Pick the perfect moment with Top Shot. Automatically recommends the best pics, where no one is blinking and everything looks just right.
• Portrait - Add elegant background blur (bokeh) to pictures. Google Photos can also make the subject of your photo pop by leaving them in color, while changing the background to black and white.
• Long Shot - Take casual, quick videos by simply long-pressing the shutter key in the default camera mode.

Requirements - The latest version of Google Camera only works on Pixel phones running Android 11 and above. Some features are not available on all devices.
