A startup company Lytro gained an explosive popularity once the company introduced an innovative and revolutionary camera which is due to ship later this year.

With Lytro, you can take a perfectly focused photo, always.

What does that mean? Below this article, you can experience it yourself.

The technology of Lytro allows a picture's focus to be adjusted after it's taken. 

The core science behind the camera is called the light field, the amount of light traveling in every direction through every point in space.

While traditional cameras add all the light rays and record them as a single amount of light, the light field sensor captures the color, intensity and vector direction of the rays of light. Then with sophisticated algorithms, the full light field will unlease new ways to make and view pictures, so the photographer and the viewer can both focus pictures after taking them.

In addition, Lytro allows you to shift their perspective of the scene, and even switch seamlessly between 2D and 3D views.

This way, Lytry lets you experience living pictures.

Today is a big day for Lytro, but I believe it is just the beginning of a bright and exciting future. Photographers and casual shooters alike will be able to create and share new living pictures. I believe that as people begin to use light field cameras, we will see an explosion in new kinds of photographic art. It will be another wonderful journey to see how people use light field cameras, see where these new living pictures travel, and discover how each person chooses to take this revolution, said Ren Ng in a blog post, Founder and CEO of Lytro.
