Here is several photos from ‘The Mirror Cube’ video backstage. For this video I made a simple holder for the iPhone from the guitar stand and a pair of office rubber bands. Then I fix tripod legs on floor with scotch tape to prevent moving during shooting. I use white window sill as background and daylight from window as main lightsource. I know that is wrong due to changes in exposure during day, but it was experiment and nothing better I could not find. Also I use paper lamp from ikea as second lightsource to vary the shades of light and add warmth in all picture. Also I add some marks on sill on backside of mirror cube to know it permanent position.
