In busy destinations it can be difficult to take new images that don’t look like postcards or cliché scenes from social media. To get a different perspective on a location, try changing the height you shoot at or the angle of view. For example, shooting really wide at 14mm or close in at 200mm can produce a new take on an everyday scene.
Getting up early for sunrise, or staying out late for sunset or low light night images will also change the colours you get to work with. There are also a lot of non-obvious images to take. Study the patterns, colours, shapes and textures in objects or buildings. Every location has an almost endless supply of things to photograph.
If you get an overcast day, think about using the macro feature on your camera or a macro lens to explore the location in close-up detail. Most of all, be patient. For the best images, you may have to wait for the right light or adapt your shooting style.
