You will find camera icon on your main screen. Click on the icon, and you will enter inside. First of all, you need to decide which camera you want to use, the front camera or the one on the back. The camera on the back has higher-resolution, and it is chosen by default.
The users just need to tap the button on top right corner to get the front camera. By tapping it again, you can go back to the camera on the back.

Before pressing the picture-taking button, you need to adjust a few things, like zoom and focus. You can focus one single object as well as zoom it. Use pinching and dragging for this. Sliding the bar left or right is another simple way to zoom in and out.

If you find light unsuitable, turn the flash on. The flash is available only in the newer models though, like iPhone 5. The flash icon is on top left side of the screen, with the lightning bolt on it.
You can also put the flash into Auto mode. Having done all, you just need to tap the camera icon at bottom centre of the screen. The picture will be taken.

You can also record videos, if using iPhone 4S or 5. To change mode from taking still pictures to video, go to the slider at the bottom right corner of the screen. The camera will go to video mode, and you can record as many videos as you want.
