What is the AE / AF lock of the iPhone camera ?:

The AE / AF lock it is quite simply blocking exposure and focus. Those initials mean the following:

  • AE: From English, Automatic Exposure, which in Spanish is automatic exposure.
  • AF: Automatic Focusm which in our language means automatic focus.

To activate it, you simply have to focus on a place you want to photograph and hold the screen. In a few seconds the function will be activated and this information will appear on the screen:

By clicking on an area we are focusing on, the camera calculates the exposure and focus for that point and then locks it. If you activate the AE / AF lock, then when you move the phone you will see that the focus and exposure are locked and will not change. You can focus on a closer object and you will see how it appears blurred and with a higher or lower light exposure, without automatically adjusting as the iPhone camera does.

When to use iOS AE / AF lock ?:

This lock comes from pearls to take the following pictures:

When something on the scene moves:

Imagine that you want to photograph a statue and at that moment a person passes by and the camera of the iPhone it detects it and instead of focusing on the statue it focuses on that camera. Locking AE / AF that will not happen since it only focuses on the element that you have clicked on to activate the function.

When there is an extreme range of exposure:

When we want to take a photo of someone and the background, for example, is very bright, the AE / AF lock it is a very good option. Focused on the person’s face the capture locks the exposure and proper focus to take the photo. We can also do it if we want the person’s face to appear but focusing on the part that appears in the background of the image.

Depth of field:

The example that we can put here is very illustrative. Imagine that we want to take a picture of the raindrops on a window. If you have ever tried it, surely you will have gone crazy to do it. Well, if we block the focus and exposure in some area, for example on a wall, and then focus the glass with drops of water, zooming in or out of the phone we must take the photo when the drops are in focus. The result is terrific.

Photographing silhouettes:

For example, if you are trying to create a silhouette, you will have to underexpose that person or thing while their camera tries to expose it correctly. To do this, direct the camera to expose the sky, press on it to lock AE / AF but, yes, making the silhouette enter the field of focus.

Create Bokeh effects by activating AE / AF lock:

This is something that the function Portrait of the iPhone It does it automatically, but if you want to create, for example, a blur effect on a close-up object, blocking the exposure and focus will come from pearls. You put the object or person in the foreground, and then lock the focus on the landscape or objects that appear in the foreground.

Once it’s set up, zoom in or out until you see the perfect shot.

When you can’t focus on an object or person:

As in depth of field, when something cannot be focused, it is best to activate the AE / AF lock at one point and then, moving the mobile closer and further away, find the correct point where that object or person focuses.
