A good approach is to combine map research with local knowledge and exploration. Online mapping tools can help a lot: terrain views show the shape of the land, and photo layers can reveal places other people found worth photographing. Detailed topographic maps are even better when available, since they can hint at viewpoints, tree cover, trails, and landmarks.

Local photo communities are also useful. Joining an area-based Flickr or similar group lets you see what others are shooting, often with geotags, and you can ask directly about locations.

Another practical way to discover overlooked spots is simply to explore on foot—activities like geocaching can lead you to parks, trails, old structures, and hidden viewpoints you might never find on a tourist map.

For sunsets, both timing and landscape matter. Season affects where the sun sets, but learning the terrain helps you choose a viewpoint with a clear horizon or a foreground that makes the scene stronger.
