Key ideas in iPhone Photography: The Assignment Series
- The iPhone's AI defaults to the closest or most central object
- The sun icon next to the focus box controls brightness
- Tapping the screen manually overrides the automatic focus point
- Sliding down reduces light intake to prevent 'blown out' white areas
- A yellow square appears on the iPhone screen to confirm where the lens is now focused
- Once a sky is pure white on an iPhone, that detail is lost and cannot be recovered later
- How to override the iPhone's automatic focus when it targets the wrong object
- Using the exposure slider to preserve detail in bright areas
- Tapping the on-screen button often causes the phone to tilt or shake
- The side volume buttons act as a physical shutter release
- Gripping the phone like a traditional camera and squeezing the volume button keeps the iPhone steadier
- The subject's face must be sharp and in focus, not the background
- Reducing physical movement when taking a photo
- The grid is a tool for intentional placement rather than just a decorative overlay
- Using the grid helps distribute visual weight across the frame for a balanced look
- iPhone settings allow the grid to stay visible to prevent accidental centering
