Architectural photograph of lighted city sky jigsaw puzzle

A few clues to get started

Explore city, architecture, travel. Look for these features as you bring the picture together:

• Follow straight lines in buildings, windows, or streets when they are visible. Repeated windows can be deceptive, so check a corner, shadow, or change of color before joining them.
• Sort open sky by brightness and color temperature. If clouds are present, follow their edges first and save smooth areas for when surrounding clusters are in place.
