Signs are one of my favorite things to photograph when I'm in a new city. If the sign is especially weird, random, funny or funky - I'm immediately drawn to it. If it's in NEON...all the better.
Photographing signs on your travels is a great way to document a culture or place. They give extra dimension (and flair! and humor!) when grouped with your other photos of main attractions, street life, food, etc.
Here are my top 3 tips for photographing signs:
1. Look for signs in the local language. Even if you have no idea what they say (you could always ask someone for a translation) you'll have a neat shot of something authentic and special to that country.
2. Look for signs in ordinary, everyday places (grocery stores, libraries, public transportation, parks). These can be great examples of the laws, history, and beliefs of a particular culture.
3. Look for signs for reference. Often, I'll shoot signs as a way to record information I may need later. It's easier than jotting it all down in a notebook. For example, if you photograph a piece of art - get a shot of the placard with the artist bio and description that goes with it. This way, if you want to do further research or share what you've found, you have all of the pertinent info in one spot.
