For this product photography class Karl uses refraction through two Dior perfume bottles to create this lovely fresh product image.

Throughout the shoot Karl highlights common problems on might face in such a shoot –  lighting the chrome details on the bottle, the transparent bottle tops and achieving the right amount of refraction.

Watch as Karl and Urs Recher tackle each challenge, clearly explaining and demonstrating the solution to each. At the end of the shoot Karl experiments with a number of alternative lighting modifiers and shows how each produces a slightly different result.
