The image goes to a wireless printer, and if there is not one near you, you can choose Print to PDF. Other choices under the Print heading include Orientation (is the image being printed in landscape or portrait?) and Size (Letter, Tabloid, Legal, Statement?) If motion was detected during the capture of the image, the photo can be used as a Living Image picture. Somewhat similar to Apple's Live Photos, with Living Image the first few seconds before you snap the shutter to take a picture is recorded as a video. This allows the image to move. With the update, you can have a Living Image picture viewed in motion whenever you load it on the screen, or you can set it as a still picture with no motion.
The changelist for the Camera app for Windows 10 Mobile includes the usual bug fixes and reliability improvements. Unfortunately, it doesn't add the Rich Capture HDR option, or one that would allow you to shoot in panorama view.
Just because they weren't included in the update now, doesn't mean that those features won't be added to the camera app at a later date. Keep your fingers crossed.
