The new camera from Lytro coming out in the next year could be a real game changer in the world of photography and cinematography. This new method of capturing image data will allow for some powerful capabilities with your images and film.
Click on the sample to give it a try.
Currently, film and digital sensors only record the color, intensity, and location of light when taking a photograph. While this information can be modified somewhat in post, one aspect of the image cannot be changed: it cannot be refocused. Once a shot has been taken the focus is locked. I'm sure you've all experienced a shot that you wish you could do over because it was blurry. The new light field camera by Lytros is going to change all that!
How Does it Work?
While typical cameras focus and concentration light on the sensor to reproduce what appears in front of the lens, it is in fact losing a very important component of the light: its vector. All that is recorded is the color of the light and its position in the image. While this provides for quality images, it does not provide for the ability to make certain changes to the final photo. This includes the ability to change focus after the photo has been taken.
So, what is a vector? It is the direction of motion of an object, or in this case a ray of light. When light hits an object such as your subject, light rays bounce off in countless directions. Some of those rays head toward your eyes, and yet others head toward your camera lens. A light field camera is able to record the angle of each ray of light that enters the camera in addition to the light's color, intensity, and location.
