You Can Finally Zoom In On Instagram Photos And Videos
At long last, you can zoom in when you you are taking photos and videos using the Instagram app. Just pinch a photo like you would in most apps to zoom, but you have to hold the pinch or it zooms back. For now its only available to iOS users after an app update. Android will get the update "in the coming weeks."
This is the kind of features that Instagram wants to grow beyond a "capture the moments" app and recent updates from the Facebook owned company seem to indicate that they know it.
