Fig. 4: Light field print encoded with 3 × 3 perspectives of a multi-coloured cube.
From: High-resolution light field prints by nanoscale 3D printing

Digital camera macro images of the cube were captured from each viewpoint denoted by azimuthal angle α and elevation angle β. The cube appeared to protrude out of the plane of the substrate. In this light field print, each colour pixel comprised 5 × 5 nanopillars (pixel pitch P = 5 µm). The same scale bar applies to each viewpoint image.
