How to Adjust The Exposure in iPhone Camera App
Most of the time, the iPhone’s “Camera” app will correctly estimate the amount of light that is needed to turn a snapshot into a great photo. But there are certain exceptions. Difficult lighting conditions can stump the smartest of cameras, it is no different with Apple’s products.
Thankfully, it’s the photographer and not the camera who makes for a great photo. Thus you can and should intervene from time to time and tell your iPhone whether the current scene is way too dark or way too bright. Here’s a tutorial on how to change exposure or “brightness” settings while working with the iPhone camera.
First of all, you will need to launch your “Camera” app via the Home Screen, Control Center or Lock Screen. Use whichever method you prefer. Then point your iPhone at the subject.
Tap the area on the screen that you would like to focus. A small yellow rectangle and a sun icon will appear. This tells us that we can now adjust the exposure. Drag your finger either up or down to adjust the final brightness of your image. Shoot when ready.
This method has a number of advantages over editing your images later on. You’ll get a live impression on what the photo will look like when finished, there won’t be a lot of compression artifacts and not a lot of reasons to edit the photo later on.
