There is a lot to say about the new iPhone5, but one thing that might not be evident is how to take advantage of the feature to take still pictures while shooting video. If you do a google search, right now the results only talk about the addition of feature, not how to actually use it. While shooting, a camera button will appear near the red recording indicator. That's it!
This is both obvious and non-obvious at the same time...that button reminds me a lot of the button to switch between front- and rear-facing cameras, so it might be easy to miss if you are trying to figure out how to take stills. A friend of mine asked how to use this feature, so I figured I'd post an example.
The image below is not a good example of what the iPhone can do as far as image quality; it's just there to illustrate where the still image capture button is located. I was moving quickly in a dark room, filming my dog in front of my shoes.
