A while ago I came across the Profoto Globe. This is a flash diffuser that basically resembles a massive frosted 60W light bulb. The image that was created was an Audi S5 power sliding on a frozen lake. An awesome image, and the globe was, among others, the key light. The result of the reflection is a soft but crisp light that allows almost direct lighting of a shiny surface with minimal harsh flare.

It was fortuitous that we were lent some Hassleblad Broncolor lights, a Scoro generator, some flash heads and light shapers. One being a globe, or Balloon as they call it.
We also took receipt of the Superdry branded Morgan three wheeler and couldn't resist rolling it into the curve and snapping a few shots. The results were great.
