Answer

Yes. No. They can both be photographed.

Work Step by Step

Real images can be projected onto a screen because actual light rays come to a focus at the image position. If you place a screen there, the image appears on the screen. Virtual images can’t be projected onto a screen. Light rays do not converge at the image position. For example, a flat mirror’s virtual image is “behind” the mirror, and placing a screen there will not lead to an image on the screen. Both real images and virtual images can be photographed because you can see both types of images with your eyes. See Figure 23–37c and Figure 23–39 and place a camera where the eye is. The converging lens in the camera/eye can make an image from those incoming rays.
