Tripod

In the climactic scene of Paradise, a tripod and 8mm camera are visible on screen.
Harada filmed part of Paradise in a school hallway.

Harada started making animation at the age of 14. At first, he photographed outdoors using sunlight.
If you take pictures in the shade on a sunny day, you will be surprised at how well you can take pictures.

Paradise features a mix of outdoor and indoor shots.
The slightly darker parts of the screen are indoor shots.

After many experiments, he found conditions for shooting indoors with the right lighting.
That means using two 300 watt blue light tungsten lamps.
