The Lytro doesn’t really look like a camera. Just look at its shape, a rectangular middle east mobile number list model of about 11.2 x 4.1 x 4.1 cm. It has two buttons, a slider and a USB port. But the most special thing is in the camera, the Lytro is a light field camera . Lytro was found by Ren Ng who receiv his PhD in light field photography from Stanford in 2006 (his thesis can be found here ). Steve Jobs was interest in this form of photography and talk to Ren Ng about using light field photography in the iPhone.
Light field?
A light field camera (or plenoptic camera) is very different from a normal camera. In front of the imaging sensor is a micro-lens array (130,000 microscopic lenses). This registers a 4D image (light from every point in a 3D environment, including the direction, the fourth dimension). What is record are actually 130,000 small images that are all slightly different. The software in the camera ensures that a 3D image is creat, where you can later choose what you want to focus on and shift the perspective yourself.
The micro-lens array also makes it possible to record 3D images with a lightfield lens, normally you ne two lenses for that. To make it simple, you could say that you don’t take one photo of an object, but dozens, all with a different focus. In concrete terms, this means that you can china numbers take a photo and then adjust the focus:Shoot first focus
That doesn’t mean that taking pictures with
a Lytro will immiately produce great ‘ living images ‘, on the contrary. You will really procedure for issuing permits for performing high-risk work by the state labor service have to experiment with the camera and see how you can make beautiful compositions with this camera. For example with the Creative mode of the camera. What you can do with it at the moment is still quite limit. You can make close-ups or photos at a greater distance with the 8x zoom. There are now about ten filters available that you can put over the images, the Glass filter for example shows depth nicely in the photo.
