BBC test card 61, 'Cardboard Kate'
BBC test card 61 flesh tone reference card for colour television cameras, featuring 'Cardboard Kate', developed by the BBC Research Department, 1976-1977.
Test card 61 was developed by the BBC to provide a fixed and uniform image of a model's face so that colour television cameras could better reproduce accurate skintones. The card was nicknamed 'Cardboard Kate' but the model was actually Lynne Holmes, an administrator working for the BBC at the time. The card is angled slightly downwards, to avoid reflection from the studio lights.
