How to Lock the Focus and Auto Exposure of iPhone Camera

The iPhone camera is one of the most popular in the world, as some studies say, such as one last January in which it was claimed that the iPhone 5 camera surpassed the Nixon in popularity on Flickr, the photography service. owned by Yahoo! It is not one of the most popular because it is one of the best of all, no. The iPhone camera has always been preferred by users because of how easy it is to use and because it is a very versatile camera that allows us to take good shots without knowing anything about photography in almost any situation.

Even so, there is still some adjustment that we can escape, as is the case of the auto focus and exposure lock. Sometimes, we may prefer that the iPhone does not decide for itself which point to focus and how much light to collect. For example, a group photo that is taken not too far away and where the group does not stop moving. It is possible that in that case the iPhone does not know where to focus, so we will have to indicate it ourselves. It is a simple process, as you can see below.

For this we will have to block the AE (from English, Automatic Exposure) and the AF (from English, Automatic Focus). AE adjusts the amount of light entering the sensor and the AF simply prevents focus from determining by itself where to fixate. Both factors are blocked at the same time and for this we will only have to choose the point where we want to focus / collect the light and press for more than one second. We will see that the square takes a couple of jumps and the banner of AE / AF LOCK.

When the lock is already operational, it will not move even if we move the iPhone. On the right side of the square we will see a vertical line with a sun used to modify the ISO, which marks the amount of light our camera needs to take a picture. To modify this value, just slide a finger up or down on the iPhone screen (it doesn't have to be on the sun icon).

I know that many of you knew this trick, but there are many people who did not know it and it is to those users that this little one is directed type and whom I hope has served and helped.
