When Instagram added video in June, Kelly and others were able to further bring to life their shots of daily North Korean life. Jean H. Lee, who just finished her assignment as the AP's first Pyongyang bureau chief and also posts on Instagram, uses the iPhone app Loopcam to share animated gifs.
Lee, a Korean speaker, said she's seen a lot of interest from South Korean Instagrammers.
Meanwhile, two tour companies, one American and another British, have taken to Instagram to promote North Korea and their trips.
The government is particularly sensitive about photographs of the country's present and past leaders, as well as shots of military-related subjects, Lee told ABC News.
But Lee is able to photograph sites the AP reporters have access to that Americans and other foreigners do not get to visit, she said.
"Hopefully by sending images from those places," Lee said, "we're broadening the view that people have of North Korea and filling in the gaps."
