While many of my images are more intimate and skyless, the glow effect works on images with sky quite well also. The image below is a more traditional nature photograph with clouds, sky, and land. Even though there was a nice glow already happening in this scene, the make-it-glow technique was still used to boost the effect and increase the sense of radiance in the image. The rollover once again shows the added glow. Notice that both the blues and the reds in the sky benefit from the added glow.
