The set is simple：a little fabric，a chair，maybe some flowers.Its users are more complex：an American mother who takes her children to visit their Mexican father every weekend，and a nine year-old boy who wants to "have a memory of us together" before his father goes back to California.They pause what they're doing.sit for a photo，and leave with a printed copy.Behind the camera is Alexia Webster.a South African photographer who sets up street studios around the world.At Studio Transfronterizo，her project in Tijuana，Mexico，passing characters offer a look at life on the world's busiest land border.Every day nearly 100，000 people legally cross from Tijuana to San Diego，California，at the San Ysidro border.
More than a decade ago Webster was photographing for the United Nations in a refugee（難民）camp in Kenya when a man told her he'd watched photographers visit for 15 years but didn't have a single picture of himself or his family.Many of Webster's subjects had escaped from war，leaving personal archives（檔案）behind.One photo could help them rebuild.
In 2011，with a printer and a temporary studio on a corner in Cape Town，South Africa，Webster invited people to pose for a free session.She printed their pictures on the spot. "Primarily it's for them，for their kids，their grandkids，their lovers，their friends，" she says. "It's a record of who they are." Webster has since put up studios in other places，from the streets of Mumbai，India to a refugee camp in South Sudan.
She gives few instructions from behind the camera. "The idea of the project is for people to rebuild their archives and reaffirm their identity，" Webster says. "I like them to determine how they want their photo to be.
