Very nice composition and lighting. Well done.
Joe Ogiba: I also like "Where the Hell is Matt?" that was done with short video clips.https://www.youtube.com/watch?v=zlfKdbWwruY
Good call. I hadn't seen this before.
Reg Natarajan: With every camera capable of ISO 12800 these days, tripods are about as useful as slide rules to me. (I'll bet some of the younger people here don't even know what a slide rule is. Trust me, you're not missing anything.)
So you're a bit of a snapshooter, eh?
Very nice indeed.
Gesture: Here is a company extending its reputation while respecting and building on its heritage, not ...
Lilianna: Cool effect, however ALL camera phones will do the same thing, this is not an Apple Innovation.
It's a CMOS shutter phenomenon, nothing to do with Apple. per se.
Trevor G: Sorry guys, but this looks like a massive con job.
1) IF the electronic shutter in an iPhone functioned in such a way that it would resolve the vibrations of a guitar string, it could only resolve one such string, because each string has a different frequency.
It might be able to resolve a particular harmonic frequency common to all strings, but I have serious doubts that that would be possible, too.
2) When the phone is placed inside the guitar the fingers, strings the bearded guy and the background are all out of focus - when the music starts the strings, the fingers and the background are all amazingly sharp. That's amazing DOF, if nothing else!
3) Check the light along the edges of the strings pre-music, with the way the light no longer "surrounds" the strings with-music.
4) The skin colour of the fingers is clearly visible when inserting the phone and switching it on, but they suddenly become stylised, sharp, black and colourless once the music is played.
The reason the skin colour is visible at the outset is because light is falling on the hand. When playing, they're in the shadow.
The rolling shutter is not resolving harmonic frequency, it's simply doing its job - and filming. It would be quite odd if a camera couldn't film a 100 meter sprint because all runners were moving at a different speed.
