Brainstorming graduate capstone projects

Hello all — I’m currently brainstorming potential capstone project ideas and am particularly interested in exploring photography and “third spaces” (informal social environments outside of home and work, such as cafés, libraries, parks, or community hubs).

I’m wondering if anyone is aware of datasets that include photographic collections or structured data related to third spaces—such as images, geospatial information, usage patterns, or metadata describing public or semi-public social environments. I recognize this may be an unconventional request for this forum, but I would appreciate any leads on relevant datasets, digital archives, or research repositories that could support this type of inquiry.

Thank you in advance for any suggestions or guidance.
