Vine update for iOS brings exposure and focus locking

Vine's six-second videos may not allow much room for artistic expression, but the company is happy to provide a little more control. It just updated its iOS app to enable exposure and focus locking; you now just have to tap and hold on a subject to prevent any surprise changes in brightness or sharpness while you're recording. There aren't any corresponding updates to Vine for Android or Windows Phone, but we wouldn't be surprised if those arrive in the near future.
