Hi Todd,

The iPhone’s camera, just as many point and shoot cameras, is an auto focus 
camera. This means it automatically focuses on what is in the centre of the 
picture. This is why Voiceover say “Focus unlocked” it simply means focus is 
not locked to anything outside the auto focus area which is in the centre of 
the screen.
As a blind person all you can do is to try and focus the camera so whatever it 
is you are taking a picture of is hopefully about in the middle of the screen 
where the auto focus area will do its job.
If you take a picture of a person Voiceover will tell you when it sees the face 
and if the face is centred and if it says “face near left edge” you can try to 
move the phone a tiny bit to try and get it to be in the centre where the auto 
focus area is located.

You can force the camera to focus on something that is not in the auto focus 
area in the middle of the screen by tapping on it, but obviously this is a 
photography feature which is of limited or no use to a completely blind person.
Note that if a sighted person taps on something off to the side, maybe a flower 
or person that is not in the centre of the frame then the camera will still use 
auto focus and focus will still be “unlocked”.
A sighted person can also “lock” the focus on an object or person on the screen 
by tapping and holding on the object or person instead of tapping it just once. 
If somebody did that and then you turned on Voiceover it would say “Focus 
locked” instead of “focus unlocked”. I have not yet discovered a way to “lock” 
focus when Voiceover is running, a double tap and hold doesn’t seem to do it, I 
tried a double tap and hold and then to tap with another finger and I tried 
force touch. On the other hand, if I toggle Voiceover off with a triple click 
of the home button and then touch and hold somewhere on the screen and the turn 
Voiceover back on, Voiceover will then say “Focus Locked”.

There are also third-party apps which allow for “manual focus” instead of “auto 
focus”, but once again these would be of no use to a blind person and the same 
applies to adjusting the exposure which you can do even with Voiceover running 
if you double tap and hold and then slide a finger up or down on the screen. Of 
course you don’t really know what exposure will be best and here it is simply 
best to let the camera of the iPhone which is a very good camera do it’s job 
and let it auto focus and auto expose the picture.

For anybody who is interested to learn a bit more about how photography in 
particular on the iPhone works even if many of the features require you to see 
what you are doing, the below article explains this quite nicely:

Subject: Focus automatic in camera

For those who have experienced taking photos using the iPhone’s camera, how do 
I make the camera before taking a photo made to automatically focus on an 
object when facing the camera in front of it?

What does it mean when it says Focus unlocked image?

That is concerning iPhone 6S iOS 10.1.1.

Please let me know.

Thank you.

Todd
