A screenshot (not photo) will include that area of the screen as well. While you have the Camera app open, press and hold the power button and while doing so also press the home button to take a screenshot (I'm assuming you have the iPhone SE since you tagged that one).
The screen will flash, indicating that a screenshot was taken, and the screenshot will be saved in the Photos app. You can then share the screenshot here through the "Attach files" button. Make sure there's nothing in the viewfinder you don't want to share with the rest of the world when you take the screenshot.
