Episode notes
Decisive Moment Reimagined
- The decisive moment in photography is fleeting but central to meaning.
- Computational tools can shift when and how that moment is captured or reconstructed.
From Rock Climbing To Light Fields
- Ren started from a love of photography and graphics to invent light-field capture.
- He wanted to refocus photos after capture, turning optics into software.
Rays Over Pixels
- Light-field cameras capture rays not just pixels, enabling post-capture refocus.
- Higher-dimensional capture moves lens work into software and leverages Moore's Law.
