We present a portable multi-camera system for recording panoramic light field video content. The proposed system captures wide baseline (0.8 meters), high resolution (>15 pixels per degree), large field of view (>220°) light fields at 30 frames per second. The array contains 47 time-synchronized cameras distributed on the surface of a hemispherical, 0.92 meter diameter plastic dome. We use commercially available action sports cameras (Yi 4k) mounted inside the dome using 3D printed brackets. The dome, mounts, triggering hardware and cameras are inexpensive and the array itself is easy to fabricate. Using modern view interpolation algorithms we can render objects as close as 33-cm to the surface of the array.
