The iPhone 7 Plus is rumoured to feature a dual-lens camera. While we don't exactly know the reason for it, some people speculate that it may be used to take a photo at different focus levels, then allow the user to edit the focus of the photo after taking it.
If you can't wait till the release of the iPhone 7 Plus in September for this functionality then you may want to check out Live Focus. Live Focus is an app that allows you to take a picture then adjust the focus later on.
It works by taking the picture at a variety of focal points, then allowing you to use a slider to adjust focus level.
The app is really simple to use. Just press the shutter button, and it'll take the different picture automatically for you. A recent update even allows exporting the pictures as a GIF to show the change in focus, which is really good.
Below is a GIF I made using Live Focus. The quality isn't great but in keep in mind this is probably because I have an old iPhone.
Perhaps, one disadvantage of using this over the stock camera app is capture speed. Since the app takes a variety of photos, it'll take a couple seconds or more to snap that one picture. So if you're after a quick shot then you're better off with using the stock camera app. However, if you're willing to keep a steady hand for a few seconds and take the photo then you may want to give this app a try.
Also, keep in mind that photos have to be taken using the Live Focus app for the functionality to work.
The app is well built with a great design. It also features some really nice filters that are quick to apply. Some premium filters are locked behind an in-app purchase. This is a bit of a bummer considering that the app itself is paid.
What I like about Live Focus is that the developers worked around the one lense limit in an innovative way. I'm not sure how often you feel the need to have a photo at different focus levels, but if it happens frequently then I'd recommend you to check out Live Focus on the App Store.
