When you look in the mirror, you see yourself flipped and not as others see you.
A mirror that is an electronic display that shows you a correct – unflipped – image.
When you take a selfie, your phone might flip the picture to show the real way you look to others instead of a mirror image. You then realize that your face is not very symmetrical.
Build a filter that takes a picture of a face and makes it subtly more symmetrical.
A view from a bridge- all around the world 🙂
Have webcams set up by volunteer representatives (in return for exposure online) all around the world, so anyone can see what’s going on any place where there are pedestrian bridges, the view, as well as get their pictures taken with the background view showing. The software detects when someone is looking into the webcam and smiling, and then it takes their photo and automatically publishes it on an online wall of photos like it from all over the world.
When you’re on a balcony and would like to extend where your camera is when taking a panoramic picture, or you want a panoramic selfie from a little distance.
Have a mechanism that at a push of a button both starts the panoramic photo exposure on the camera and also start rotating the camera from one end of the scene to the other.
