Are your photos blurry? A big reason for this blurriness could be that your camera isn’t focused correctly.
In this selection, the camera decides what the focal point is for you. The camera bases the focal point on what is most prominent in the viewfinder. This might work when your subject is obvious and there are no other distractions.
This setting allows more control, by letting you choose your own focus point. This will help a photographer who knows where they want to place their subject.
If your camera is having trouble detecting a focus point, you can change your setting to manual and focus the camera yourself.
Issues with focus:
-Try backing away from your subject. If you are too close, the camera can’t focus.
-Change your depth of field. If your depth of field is too shallow, it’s hard for your camera to tell what subject you want in focus.
-If the shutter speed is too slow, the camera picks up the movement and makes a blurry picture. Make sure your shutter speed is faster than your focal length.
