Photos without focus

It’s no secret that now, in order to take a photo on a regular, let's say, soap box, you need to press a little button, after that the lens will focus on the object and then, when we see a clear image in the viewfinder (or on the screen), press end and take a photo. In principle, everything is simple and clear.



But Lytro decided to change this process. They declare that they will revolutionize the world of photography. With the help of their cameras, you can take photos without focusing the camera on the object. A sharpness can be adjusted in post-processing. Honestly, when I first saw this, it seemed to me that I was sleeping.

This technology was developed at Stanford University under the leadership of Dr. Ren Ng for a long time - about 50 million dollars were invested in it. The company showed a few photos, so that we could quickly understand what they invented. So, in the gallery, the link to which is below, you need to click the mouse on the desired part of the photo and that is where the photo will focus, and everything around will become blurred.

Example:
Focus on the girl


Or on flowers


Unfortunately, on Habré you can not insert Flash into the post, so you have to get on the site and play there. Go to the gallery and in the photos click on the places on which you want to focus.

And here , by the way, explain in detail how it works.

If this is not a fake and such cameras really will be, then it will definitely be a revolution. Lytro promises to release the first cameras by the end of this year.
