Let me tell you guys after reading this short article you would change your mind about getting an expensive DSLR camera. This photography tip is the Bomb. No kidding. And I have my pictures to show you so you can compare it for yourself.
Inappropriate focus is the most common reasons why iPhone photos end up blurry. You know the focus is wrong when the important parts of the image are blurry while others are sharp, or when everything is blurry even though there is abundant light in the scene.
Most iPhone users don’t adjust the focus themselves, and that works 95% of the time. With that said, there are times when autofocus fails, particularly when your photo has large uniform areas, when some parts of the photo are close to you while others are far, or when the scene changes rapidly.
Interestingly, you are more likely to experience problems with focus on the newer iPhones, especially iPhone 5S which has a significantly smaller depth of field. While the small depth of field (which is caused by larger aperture) is awesome, it also means that you have to set your focus more carefully.
The best thing you can do to avoid out-of-focus images is to always set the focus yourself. Simply tap on the part of the image that you want to be in focus, and your iPhone will take care of the rest.
In this example I set the cake in the foreground, which set the focus (and exposure) on the cake. Notice how the cake is now really sharp, while the picture frame and candy in the background are blurry. You want to make sure that the important parts of the image are in focus by tapping the screen there.
However, even when you set the focus perfectly, the iPhone will automatically try to change it as soon as anything changes inside the frame. This can get quite annoying, especially if you’ve set the perfect focus yourself and all of a sudden it’s lost just because somebody walks into the scene.
Even worse, sometimes the iPhone will try to refocus exactly when you’re trying to take a photo, but then the iPhone starts refocusing.
As you see in the camera shoot I have locked the focus, which prevents the iPhone from refocusing when there are changes in the frame. You can lock focus (and exposure) easily by holding down your finger for a couple of seconds where you want the focus to be – a larger yellow square and the text AE/AF LOCK appears when the focus is locked.
Then, you’ve essentially disabled autofocus and the iPhone won’t adjust focus no matter what happens inside the scene, which is particularly useful when you expect someone to walk inside the frame and you want to make sure that the focus stays unchanged. To exit focus lock, simply tap the screen again.
While it requires more effort to set the focus manually every time you take a photo, it’s definitely worth doing if you want to make sure that your iPhone photos are always sharp.
