Notice the lettering
Pay attention to the way a name is written and how it fits the doorway. Collect your impressions in words rather than trying to photograph every sign.
Look at useful objects
Handles, baskets, awnings and display stands reveal how a place works. Keep observation respectful and give people room to go about their day.
Take one idea away
Choose a detail that changed your impression of the street. Write a short caption that explains why you noticed it.
