Strictly speaking, the definition of the word “glow” implies that the object in question is giving out light on its own. But the weekly challenge, as presented here, includes scenarios where things may not be really glowing, but appear to do so. With that in mind, here is a picture that appears to show trees whose leaves are glowing. But this is only a trick of the light. The effect is due to the angle of the light of the sun coming through the trees. If you look at the leaves from another angle, as they appear in the left side of the picture below, it is clear that the leaves do not really have a glow. Perhaps I could also claim that the object in the background (which you might recognize) also has a certain glow to it when seen from this angle.
