Lysfeltkameraer

Lysfeltkameraer, also known as light field cameras, are a type of camera that captures not only the traditional 2D image but also the light field information of a scene. This additional data allows for post-processing techniques such as refocusing, changing the depth of field, and even altering the perspective of the image after it has been taken. The concept of light field photography was first introduced by Adelson and Bergen in 1991, and since then, various technologies have been developed to capture and utilize this information.

One of the earliest and most well-known light field cameras is the Lytro, which was released in 2011. The Lytro camera uses a micro-lens array to capture the light field information, allowing for post-processing features such as refocusing and perspective shifting. However, the Lytro's image quality and processing speed were limited by the technology of the time.

More recent light field cameras, such as the Raytrix and the Raytrix R11, use different technologies to capture the light field information. The Raytrix R11, for example, uses a single-lens, single-sensor design with a rotating diffuser to capture the light field information. This allows for higher image quality and faster processing times compared to the Lytro.

Light field cameras have a wide range of applications, from professional photography and cinematography to scientific research and virtual reality. They allow for greater creative control and flexibility in post-processing, as well as the ability to capture and analyze the light field information for scientific purposes. However, the technology is still relatively new and expensive, and the image quality and processing times may not yet be on par with traditional cameras in all situations.
