I wanted a Mockup of a Phone that looks like iPhone, but with full-screen , from "edge to edge". I wanted it classy and glossy and slim :) So created a 3d Model and rendered it in HQ.
In Photoshop i separated everything in a different layer. All Phones, All Objects, All Shadows, All Highlights are in separate layers. There is control over the Background (Colors & Shadows), over the glow Effect on the Phone Button and over the every option of the Spheres including color change.
