So you have an iPhone 6S or 6S Plus. 

With a tripod and a few extra pieces you can start to get creative. Attached to the tripod is TARION Model TR-S120 Track Slider Stabilizer which in turn has the ShoulderPod S1 Smartphone Grip and R1 Pro.

On the Shoulderpod R1 Pro is the Sony QX10 and HTC Re used for a few stills. The below video shows a shot of the church, taken on the iPhone 6S Plus, HTC Re and Sony QX10. Each photo is labelled. Finally the iPhone 6S Plus is used to film in 4K using the slider for effect.
