I'm not sure why people think this feature is a gimmick.
If 0% of viewers can see a live photo you are trying to share on the web then I think it's clear why people think this feature is a gimmick.
Don't take my snarky comment wrong. As a photographer then I was actually very very excited for this feature. But after using it for but then several things became very clear as to why this CURRENT version is a gimmick:
1) Sharing. The limitations in showing a photo are a big deal. You wanted to sell the forum as to why the gimmick isn't a gimmick but you can't show us the Live Photo that is supposedly so amazing.
2) Low quality of non-Keyframes. The comoression of the surrounding frames are not clear or high quality. So you have a good shot surrounded by moving blocks
3) Blur when launching animation. These aren't the Harry Potter photos people expected because that blur when you activate a shot is just jarring. Apple needs to find a way to loop the file from the main shot to make it more fluid.
4) Tripod Required. Okay, not "required" but the slightest movement at such a low frame rate makes it very unpleasant to view.
And now the big one that will upset people...
5) Apple did Live Photos wrong
While the idea of grabbing surrounding frames around a picture makes sense, it seems like the right way to do this is to turn a high quality 4K video burst into a photo. This may create a very small workflow (edit, trim, save) but the results would be more consistent frames and far more visual appeal.
Okay well that's my view. I'll keep using it because It's a good 1.0 start but it won't graduate from "gimmick" for a generation or two and I definitely wouldn't say this particular version of Live Photos is a reason for someone to buy a 6S.
