Apple's new iPhone 7 Plus features a rear dual camera setup that can add a blur effect to images among other tricks. FabFocus, a new app that uses AI, promises to bring the exclusive feature to older iPhones.

Ever since Apple released the iPhone 6 and iPhone 6 Plus in September 2014, it has always given the larger 5.5-inch Plus models more advanced camera features than the 4.7-inch standard variants. Both the iPhone 6 Plus and iPhone 6s Plus featured the same megapixel rear cameras as their smaller siblings but included OIS (optical image stabilization) as the major differentiating camera feature separating the devices.

This year's iPhone 7 and iPhone 7 Plus continue Apple's strategy of offering a more compact 4.7-inch smartphone and larger 5.5-inch phablet, including using the iPhone 7 Plus' rear shooter to appeal to photographers and photo enthusiasts in a big way. The iPhone 7 Plus packs in two 12-megapixel rear cameras for a dual-camera experience that allows users to bring DSLR-like depth of field and bokeh effects. iPhone 7 rocks a 12-megapixel rear camera and finally gains OIS (optical image stabilization).

Free iPhone 7 deals and Samsung's recall of the Galaxy Note 7 have led to increased sales of Apple's new iPhones. Reports have claimed that Apple has had to increase iPhone 7 Plus manufacturing, as more iPhone users are making the jump to the larger 5.5-inch model, with the dual rear cameras being among the major reasons.

If you're holding out to upgrade to next year's iPhone 8, purchased an iPhone 7 or have an iPhone 5s, iPhone 6, iPhone 6 Plus, iPhone 6s or iPhone 6s Plus, a new app promises to bring the iPhone 7 Plus' exclusive feature to older iPhones.

The iOS camera application is created by Second Verse and is called FabFocus. The company has posted images showing how images look using its app on older iPhones, and the results look similar to the iPhone 7 Plus' popular blur effect. The app includes three distinctive features that can be easily applied with one touch. These include Automatic Depth of Field, Bokeh and Quick Touch Up.

"For novices without any previous experience or advanced photographers, FabFocus uses facial recognition to bring DSLR-like depth of field and bokeh effects to any iPhone," writes Second Verse on its webpage for FabFocus.

For a better idea, here are the features in store, according to the developers:

Automatic Depth of Field

Using advanced facial recognition A.I., FabFocus detects people in the foreground and automatically blurs what it distinguishes as the background. It's that easy to take an amazing portrait with a professional depth of field effect.

Bokeh

Quickly adjust blur and transform any point lights into customized aperture shapes like hearts or stars!

Quick Touch Up

For minor adjustments, use your finger with the built-in tool to get your photo just right within seconds.

The developer has also posted images on its site to give you an idea of how the app will enhance your photos and add the iPhone 7 Plus' camera effects to your iPhone.

FabFocus is expected to be released on the App Store in the very near future. It's unclear at this point if FabFocus will be released as a free or paid app. We'll be sure to update you on when FabFocus is available and see if it delivers upon its promises.
