Setting off jewelry
Inspiration for setting off and lighting jewelry may be gleaned by looking at jewelry adver tizements in magazines . But there can be no substitute for examining a piece by holding and rotating it beneath different light sources . While black , blue or even red velvet is often used by jewelers to display ivory , gold and silver , it is not an imaginative background for photography . The best natural backcloths for single pieces of jewelry are clothes or simply fabrics and , of course , bare skin . Other back grounds include wood , cork , coal , crystalline rock and coral for pearls . If transparent gem stones are placed on a colored background , a small piece of white paper attached to the back of the stone prevents the colored background shining through .
As with crystalline rocks ( see p . 116 ) , direct lighting of faceted stones may cause problems if light is reflected back towards the camera . Although indirect lighting with a diffuser ( see p . 152 ) between the light source and the sub ject or , with a light tent ( see p . 152 ) around the subject , will eliminate reflections , gems will inevitably lose some of their natural sparkle . Gold and silver items can also be photographed inside a light tent or by indirect lighting by shining light sources on to a reflector encircling the camera lens . For gold objects , the reflector should be covered with gold - colored rather than aluminum foil .
Lighting gold
A Multiblitz Minilite 200 flash fitted with the light box diffuser gave soft , even lighting for this brooch made from a real orchid coated in gold . Lens Hasselblad 80mm + 32mm extension Mag . on film x0.5 Mag . on page × 0.6
Highlighting opals
Natural sunlight brought out the iridescent colors of the opals in this bracelet . I wedged it into deep folds of material ( see right ) to hide the wristband . Lens 55mm micro - Nikkor Mag . on film x0.4 Mag . on page x3
Enhancing a cameo ▷ This brooch has been carved out of a cameo shell , so I used such a shell to offset the brooch . I wanted only the cameo to be sharp , so I separated the two with matchsticks , wedged into modeling clay , as shown above . Lens Hasselblad 80mm + 55mm extension Mag . on film × 0.75 Mag . on page × 4
