Please open "Settings" and select "Camera" > "Preserve Settings". You have three options to choose from Camera Mode (e.g., Video or Square), Filter and Live Photo.

Most people who enjoy photography are familiar with the rule of thirds. It's one of the basic rules you should follow when taking photos.

In short, you should place the subject of a shot on one of the four intersecting lines of a 3×3 grid. However, in order to take full advantage of the rule, you need to enable the on-screen grid in order to view the four intersections. Gridlines can also be used for other composition issues, such as keeping the horizon level or making sure walls and buildings are precisely at 90 degrees.

If you want to improve the quality of your photos, you need to start experimenting with focus and exposure. By understanding how these two functions work, you'll be able to take more professional looking photos. Simply put, the exposure determines the brightness of the image, while the focus determines the sharpness of the photo.

On the iPhone's camera, you can lock both values manually. This means you can customize the lens more effectively.

To manually lock focus and exposure, open the Camera app, then tap and hold the photo in focus. After a few seconds, you'll see the AE / AF lock banner pop up at the top of the screen.

A timer is one of the most commonly used camera Settings for front-facing shots. If you love taking selfies, then it is the perfect tool for you. You can place your phone in a certain position, with the camera pointing at the person, and the timer only kicks in when you press the shutter button, leaving your hands free to pose as you like.

To use the timer, click the stopwatch icon in the top bar of the camera window. You can select a 3-second or 10-second timer.

There is usually a shutter sound when taking pictures and most people don't like it, especially in public. It's as if it's telling everyone, "I'm taking a picture."

Unfortunately, there is no way to permanently turn off the shutter sound. However, you have two ways to prevent the sound. You can use the mute switch on the side of the device, or you can use the volume buttons to turn off the volume completely. If you use the latter, you will need to do this before opening the camera app, as the volume buttons will take photos in the camera.

Previously, we explained that exposure affects the brightness of an image. But how do you change the exposure?

It's pretty simple. First, open the Camera app and tap anywhere on the screen to bring up the focus.In addition to the focus, you will also see the sun icon. Click and hold on the icon, then swipe up and down to adjust the offset as needed.

Are you a traveler? If so, you will find it useful to enable geolocation on your photos. You'll still be able to know exactly where a particular photo came from years later.

To turn on geotagging on your iPhone you need to go to the privacy menu. Go to Settings > Privacy > Location Services > Camera and select Use app.
