## Caption / Quote

> "The ngoni's bowl is turned from stacked walnut rings — the same segmented technique used for the kora and ashiko drum. The goatskin head is stretched and dried in place, tuned by ear and by memory."

## Photography Notes

- Use natural light (window light); avoid harsh studio shadows on goatskin
- Show ring glue lines clearly in the bowl photo — they are a design feature, not a flaw
- Include a coin or ruler in at least one part photo for scale
- Capture the konso detail close-up: this is the most visually distinctive hardware element
