02 · WHERE IT BEGAN · BRAZIL, 2018–19

Put the tools in people’s hands, and stay until they can use them.

Helping people is what brought Rikki to Brazil. The teaching began there, in a classroom, before the first lesson online.

The classroomRIKKI TEACHING A CAMERA CLASS · BRAZIL
THE CLASSES · FREE, FOR YOUNG PEOPLE

Free camera and photography classes for young people from the favela communities of Niterói and Recife. Hands on from the first class: the rig on the table, then in their hands.

It drew on London, where Rikki directed live broadcasts at Kensington Temple and trained new camera, sound and lighting operators.
