How to Hold the iPhone

Get the sharpest images possible without the risk of dropping your iPhone using this technique: 

1. Place the iPhone on the palm of your non-dominant hand, using your little finger to support one side of the iPhone and your thumb to support the other. The three middle fingers stay at the back of the iPhone to provide support.
2. Use your dominant hand to support the bottom of the iPhone, sitting partially underneath your other hand. 
3. Use the thumb of your dominant hand to change any of the settings and operate the camera. 

Bonus tip: Tuck your elbows in and keep them close to your body for a steadier grip!
