How are images captured?
The Lens. A camera lens takes all the light rays bouncing around and uses glass to redirect them to a single point, creating a sharp image. When all of those light rays meet back together on a digital camera sensor or a piece of film, they create a sharp image.
Is human eye better than camera?

Do cameras produce real or virtual images?
In a real image the light rays actually are brought to a focus at the image position, and the real image may be made visible on a screen—e.g., a sheet of paper—whereas a virtual image cannot. Examples of real images are those made by a camera lens…
Can real images be photographed?
Yes. Any camera that’s capable of photographing actual objects is also capable of photographing real and virtual images. If you stand in front of a mirror and take a photo, you’ll get a photo of the virtual image. Crowell points out, virtual images can be photographed; light does appear to come from them.
Can a virtual image be seen by the human eye?
Although a virtual image does not form a visible projection on a screen, it is no sense “imaginary”, i.e., it has a definite position and size and can be “seen” or imaged by the eye, camera, or other optical instrument.

What does a virtual image look like?
A virtual image is right side up (upright). In flat, or plane mirrors, the image is a virtual image, and is the same distance behind the mirror as the object is in front of the mirror. The image is also the same size as the object. These images are also parity inverted, which means they have a left-right inversion.
What is the difference between a real and a virtual image?
The main difference between real and virtual images lies in the way in which they are produced. A real image is formed when rays converge, whereas a virtual image occurs where rays only appear to diverge.
Is behind the mirror real or virtual?
Virtual images are always located behind the mirror. Virtual images can be either upright or inverted. Virtual images can be magnified in size, reduced in size or the same size as the object. Virtual images can be formed by concave, convex and plane mirrors.
Why real images are always inverted?
A real image occurs where rays converge, whereas a virtual image occurs where rays only appear to converge. Real images can be produced by concave mirrors and converging lenses, only if the object is placed further away from the mirror/lens than the focal point and this real image is inverted.
