Quickly Open the Camera
When you want to take a quick picture with your iPhone, it can be a little cumbersome to wake the iPhone, move the slider to unlock it, find the Camera app, and tap it to open the camera. If you are hurrying to get a shot, this process may seem to take an eternity.
To speed up the process, you can access the camera from the iPhone lock screen. Simply press the Home button or the Sleep/Wake button to bring up the lock screen. You will see a camera icon just to the right of the unlock slider. Drag the icon to the top of the screen, and the Camera app will open and be ready to take pictures.
Using the On-Screen Shutter Button
When you touch the on-screen shutter button to take a picture, the camera does not actually take the picture until you lift your finger off the button. When you need to hold the camera very steady for a shot, tap and hold the shutter button as you are preparing to take the shot. Then, gently lift your finger to take the picture.
Use a Different Shutter Button
In addition to the normal shutter button on the screen, you can use the iPhone’s “Volume Up” button to take photos. Depending on how you hold the iPhone, it may be easier to reach the “Volume Up” button than to tap the on-screen shutter button.
Additionally, if you plug the earbuds ( or other three button headphones) into the iPhone, the “Volume Up” button on the headphones can also be used to take photos.
