Popular photo-sharing platform Instagram already allows users to export its photos to other networks, but inside the app has mostly been a walled garden — until now. Today, Instagram CEO Kevin Systrom and Hipstamatic CEO Lucas Buick told Fast Company that the two companies would be announcing a partnership, allowing photos taken with Hipstamatic's photography app — which includes a wide set of filters and effects — to be directly imported into Instagram. When the feature is unveiled, Hipstamatic users will be able to push their photos, including added tags and comments, into Instagram. Photos will be marked with a "Taken with Hipstamatic" attribution that links back to the app, potentially providing a big revenue boost for Hipstamatic.

Hipstamatic won't be the first app to add Instagram export: 100 Cameras in One claimed that title last year. However, Hipstamatic is one of the most popular photography apps, and Instagram stands to gain a lot from better integrating its community. "People post Hipstamatic photos on Instagram all the time, and we just want to make that experience easier," says Systrom. He says it also opens the door to other app developers: "I'd imagine if the experiment takes off that you'd likely see more API clients being allowed to do the same in the future."

Instagram integration will be coming in an update to Hipstamatic that rolls out tonight for iOS. The update will also revamp other sharing features, letting users auto-tag lenses and effects, upload to multiple streams simultaneously, tag Facebook friends, view a photo's history, and zoom photos or swipe through them.
