Deconstructing Facebook Paper's photo panner

Of course this feature is far from new / original. This app featured this effect years ago https://itunes.apple.com/us/app/photoloupe/id409722314?mt=8

Nice post! Another similar control http://github.com/chroman/CRMotionView

If anyone is interesting, I wrote a proof-of-concept Android implementation of this UI. Not as polished as this though. I didn't make any attempt to ensure the scrolling time was consistent for different image sizes, and left out the scrollbar. But this code would get you started.

Sweet new blog, goes straight to the iOS reading list.

I haven't used Paper yet, but is the photo panner different than the one used for large images on iOS 7's wallpaper/lock screen?

Yep, it's functionally very similar

Truly wonderful post. Curious though, could something like this be replicated with HTML5 and JS?

Thanks very much! There's a great HTML5 clone of the same feature https://github.com/tregoning/photoTilt

A thousand thanks to you good sir!
