Light Fields
A light field is the highest quality hologram you can make on a Looking Glass display. Think of a light field as what a RAW file is to a JPEG (or .webp if you're one of the cool kids!). A light field photoset contains all of the information originally captured by the camera, meaning that you can adjust the focal plane in the photoset to focus on an item in the foreground or the background.

There are a few different methods to capture light fields, including Linear Capture, Arc Capture and View Shearing Capture. View shearing capture is only possible on virtual cameras in 3D software.
While you can have an theoretically infinite amount of images in a light field photoset, there are diminishing returns above 45 views. Generally, there is a small difference between 45 and 99 views in that items that are further away from the focal plane of the Looking Glass display will appear slightly sharper, but it is very minimal. For most cases, we'd recommend 45 views, but feel free to experiment!
In general, you'll want your light field captures to be at least 3840x2160 in resolution per frame. Dropping below this will cause a loss in sharpness and visual fidelity!
Currently, light fields need to be captured at a constant speed. In 3D software, you'll want to make sure your keyframes are set to linear. If they have easing on them, it will stack up too many similar frames and cause some visual artifacts.
