This is a sunset from the Lake Street Bridge. It's a pretty sky and contrasts nicely with the bridge silhouette.
The photo didn't start out this way. The sky was fine but the bridge was too dark. See photo two ... the original.
With photo editing software, I kept the sky bright but lightened the dark bridge. Lightening up the darkness.
Street lights would have added interest to the picture. The lights weren't on yet ... so in the final photo I turned them on.
