How to Adjust Camera Exposure on iPhone
The iOS camera always has the auto-focus and auto-exposure feature. However, after a long wait, you can independently tap to set the focus and then adjust the exposure separately since the iOS 8 has released. In this article we’ll show you how to use this feature to take better photos with your iPhone.
Why is Exposure Compensation Important?
Exposure determines the amount of light that reaches the camera’s sensor, and therefore affects how bright or dark the photo will be. Exposure is controlled by three parameters:
- Aperture: the size of the opening in the lens determines how much light reaches the sensor
- Shutter speed: how much time the shutter is open for determines how much light reaches the sensor. The longer the shutter speed, the brighter the photo will be.
- ISO: the parameter determining how sensitive the sensor is to light. The higher the ISO, the brighter the photo will be.
The aperture is a fixed size so this can’t be used to change exposure. However, shutter speed and ISO cab be altered to manually adjust the exposure of a photos.
How to Adjust Camera Exposure on iPhone?
Step 1: Launch the Camera app and point it at the subject you’d like to take a photo of.
Step 2: Simply tap on the screen to choose where you’d like to focus. You’ll see a small sun icon right next to the focus box that appears.
Step 3: Tap and hold on the sun icon that appears next to the focus box. Keep your finger pressed on the screen and you will see a slider that allows you to adjust the exposure.
Step 4: Swipe up or down to alter the exposure: up for brighter/larger exposure, and down for darker/lesser exposure.
Step 5: Stop the swiping when you reach the desired exposure level. You can then click to shot the picture.
If you are unhappy with the result and want to start over then tap on the screen again to focus and then adjust the exposure by sliding up and down. It is a really nice feature that can make it easier for iPhonegraphers to take nice and amazing photos.
