Tap and hold on your screen. You will see your item move in and out of focus. At one point, the picture will become crisp and clear but then it will blur again. When you release your finger, you will see the AF/AE Lock HUD and a blurred image.
AEL (aka AE Lock) is a function that can be used when you want to reframe the scene, but keep the current exposure from changing. It allows the camera to maintain the same brightness between shots. The AEL function is useful when shooting a number of pictures that you want to stitch together later into a panorama.
Set just to the right of the viewfinder, the Nikon D5200's AE-L/AF-L button enables you to lock focus and exposure settings when you shoot in autoexposure and autofocus modes. Normally, autofocus and autoexposure are locked when you press the button, and they remain locked as long as you keep your finger on the button.
5Take the picture. To lock in the exposure for more shots, keep holding the AE lock button. You can also note the shutter speed and aperture, switch to Manual mode, and dial in those values yourself. This told the camera that he and his horse should be exposed correctly, regardless of the bright sky beyond.
You sure can disable it. Ignore the first post. Tap the object you want to focus, but hold your finger on the screen for a few seconds, when the square starts to pulse, release your finger. The square will be gone & AE/AF lock will appear at the bottom.
This is where focus lock comes in. To use it, point your camera at the subject and half press the shutter button. You should hear a beep and see a light come on in the viewfinder to let you know the camera has focused. The focus will now remain locked while your finger is still holding the shutter button half down.
The auto exposure lock (AE-L) function on a DSLR camera lets you physically lock the exposure reading from anywhere in the scene. You can use it on its own or at the point where you focus the image. It lets you take an exposure reading independently of where you want to focus.

It means SHUTTER PRIORITY. In this mode you will choose the shutter speed to use and the camera will determine the aperture to use for a properly exposed photograph. Shutter Priority is good for fast moving subjects where you want control of the shutter speed to stop the action.
AI camera means better algorithms and AI magicAs the mobile benefits from machine learning, the camera AI on mobile phones, at its most basic level, is used to quickly and automatically recognize what is in a scene. Meanwhile, it can automatically differentiate between foreground subjects and backgrounds.
The camera focuses and sets exposure for photographs when the shutter button is pressed halfway and focus (AF) and exposure (AE) remain locked while the shutter button is kept in this position. Use focus and exposure lock to compose photographs with off-center subjects.
How use AE/AF Lock?
- Open up the camera from the camera app.
- Tap the screen to focus and expose your image.
- Hold on your focal point until you see an AE/AF Lock banner on the screen, to lock exposure and focus.
- Press the shutter button to take a photo.
- To unlock, tap anywhere on the screen.
ISO (International Organization for Standardization) is an independent, non-governmental, international organization that develops standards to ensure the quality, safety, and efficiency of products, services, and systems.
Exposure Compensation allows photographers to override exposure settings picked by camera's light meter, in order to darken or brighten images before they are captured. The image is now properly exposed, with the whole scene appearing much brighter compared to what the camera thought was the right brightness.
Aperture (exposure modes A and M): Press the selected control and rotate the sub-command dial until F icons appear in the viewfinder and the control panel. To unlock aperture, press the control and rotate the sub-command dial until the F icons disappear from the displays.
What is the difference between auto focus and auto exposure? Auto focus automatically keeps the image sharp; auto exposure automatically controls the brightness of the image.
Description: Auto exposure is a shooting mode on a camera where the camera selects all aspects of an exposure. The photographer frames the subject or scene and the camera chooses an aperture, shutter speed, and ISO without the photographer's input.
Pretty easy, if you want to lock exposure, press half-way and hold the shutter button and recompose. If you don't want to lock exposure, simply don't press the shutter button half-way. Works like a charm.
In digital camera terminology, sports mode is a type of scene mode photographers can use to help take better sports or action shots. The sports mode will usually automatically set the camera to increase the shutter speed in order to freeze the action in the frame.
The Shutter Release Button AE-L is a menu point in most Nikon cameras. This menu setting allows you to choose what pressing the shutter button halfway does. By default, a half-press locks the focus and exposure until the button is released.
A press of the rear AE Lock button (marked with an asterisk icon — Canon's symbol for AE Lock operation) in P, Tv, or Av mode will lock in place the exposure settings for whatever lighting the camera is reading at that moment.
Flash exposure lock (FEL) enables the camera to remember the exposure for any selected area of the subject while you recompose the image in the viewfinder.
The lock switch locks the wheel on the back so that you don't accidentally change exposure compensation. It doesn't physically lock it (the wheel will still turn) but it turns off the function.
The LOCK switch only prevents the rear dial from changing the exposure compensation (or aperture in manual exposure). It doesn't lock anything else, or any other functions (like menu or playback control) of the rear dial. We can change what the LOCK switch does in the C. Fn.
