I purchased the new iPhone 7 plus because of a really cool feature that allows you to create depth called the “Portrait Feature”. I like this because in one second you can take a photo that makes you look like a total professional! Of course, you need to have an interesting subject, good composition and stellar color levels but anything can be done these days with filters and settings.
Here is a link to the info I read… https://www.apple.com/newsroom/2016/10/portrait-mode-now-available-on-iphone-7-plus-with-ios-101/
A recent great shot I took trying this tip was at a shower I threw for my niece. Here is the photo shot in portrait of the cake with a “letterboard” behind displaying a shower message. A few tries to get things centred correctly in the frame and voila! One click and I think it turned out pretty great.
