📸Filming real-world content

The HLD system can also be used to capture real-world footage. One of the ways you can achieve this is by filming an individual on a white background. There are a few techniques that help reinforce the HLD's impact .

Camera Position and FOV

For the best effect, you should use a zoom lens — around 75mm or a 2.5x zoom level on an iPhone. Shooting on this lens length will make the person feel like they're standing on the floor of the holographic stage, though it does mean that the camera has to be quite far away from the subject.

Wide angle lenses like the standard lenses in smart phones will cause fish-eye effects which will need to be corrected in post.

Solid Color Background

Pure white will render as transparent on the HLD, allowing the alcove to shine through. You can also have the background be a solid color — this will apply a tint effect to the alcove. To have a dynamic filming environment, using a white background and colored lighting can allow you to change the effect while you record.

Shadows

When filming content you should use a soft light box to cast a shadow behind the individuals being filmed. The shadow cast by the individual should be soft and dispersed.

Reflections

Reflections can also make a big impact in HLD displays. For filming content, we recommend placing a piece of reflective acrylic on the floor and have the individual stand on it. This will create real reflections, which will come through in the display.

Our filming setup consists of three main elements, a soft box light, reflective floor, and white backdrop. In this shot, the camera is behind us, it's further away from the subject because we're using a zoom lens to counteract any perspective distortion that you would normally get in a lens with a wider field of view.

Previewing and exporting for HLD playback

Once you’ve recorded your video, we recommend opening it in HLD Author.

HLD Author lets you:

• Preview how your content will appear on a Hololuminescent Display

• Automatically export the video in the correct format for playback on the included HLD Demo Media Player

This is the easiest way to confirm framing, depth, and orientation before deploying content to a device.
