In the world of Instagram, photographers run wild, capturing everything from the extraordinary to the ordinary. Doors would appear to fit in the latter category but Caryn Cullinan's Instagram account may make you re-consider how you look at entrances.
Seen here, a dramatic entrance in Barcelona, Spain.
But what is it about doors that captured Cullinan's focus?
Her interest first revealed itself on a trip to Florence, Italy, where she started to gravitate toward doors. The interest quickly turned to a passion.
"There's a story behind every door," Cullinan told CBS News. "Wherever I am, I like to find a door that reflects the culture, and I love being there in the moment, capturing it and tagging it on my map."
For Cullinan, the doors are much more than just an entry way -- they're an extension of culture. She points out that with a single photo of a door, one can almost instantly know where that door is from.
"It just tells a lot," she said. "Behind every door is a story -- a reflection of architecture and the city and the culture."
