Landscape Photography and iPhones were never the most comfortable pairing, but there's no reason it can't be done with a little care and attention. We've put together some hints and tips to help you out.
The biggest problem is always going to be stability - the iPhone is light and landscapes large. The slightest movement will result in blurred detail so be mindful when choosing a subject that it will bear close inspection.
Secondly, landscapes generally look best in a near letterbox format - this is not the default format of the iPhone so some cropping is needed. 16 x 9 is a good place to start.
Never, ever zoom on the iPhone - you'll get much better quality by cropping in software after the picture has been taken.
Choose the subject carefully, hazy winter scenes are great for phone snaps - the detail we are worried about is lost in the haze and the light is gentle and soft. It's possible to capture a really good exposure in the Phone in this kind of light.
Do some light touch editing. There are some great apps out there - I recommend Snapseed on the Phone, its available in iOS and Android versions and there are lots of tutorials available on the web.
There are also some excellent apps that take over the camera in the iPhone - ProCamera is my current favourite - amongst its many strengths it can produce a RAW file which gives a lot more data which gives you more control in post processing.
The best thing about the iPhone? it's the camera in your hand - I've taken several shots now that only existed for seconds because the light was changeable. It's portability means I can grab a shot any time, with no notice.
