What gets decided before the first frame
Four things. Settled at the start and untouched all day.
Relative scale. A signet ring and a thin band don’t take up the same real space, but they do have to take up a similar proportion of the frame. Move in on the thin one so its detail reads, and in the grid it’ll look bigger than the signet. And the customer gets a surprise when the box opens.
Light direction. If the shadow falls right on piece three and left on piece four, the whole row flickers. Nobody can say what’s wrong. Everybody notices something is.
Camera height. It changes the perspective. A ring seen from directly above and one seen from thirty degrees aren’t the same ring.
The background, at the same tone across all thirty-five.
None of this is hard to get right on one piece. What’s hard is holding it thirty-five times in a row in a single day.
Metal has no colour
This explains almost everything that goes wrong when you photograph jewellery yourself.
A matte surface has colour: it looks the same from wherever you stand. A polished one doesn’t. What you see is the reflection of whatever is in front of it.
A gold ring on a white table in a white room reflects white. And it comes out as a uniform band, weightless, the colour of a toy.
So the question isn’t how to light the ring.
It’s what to put around it for it to reflect.
What brings gold alive is having something dark and something light to reflect at once. That contrast inside the surface itself is what your eye reads as weight, and as price.
