Lytro light field camera passes by the FCC, shows us its tasty internals
The Lytro light field camera is an incredible feat of engineering. If you’ve never heard of this elongated boxy camera before, then know that it doesn’t just look different to every other camera out there, it functions very differently too.
The premise of the camera lies in its ability to capture the light field, that is besides the color and intensity it also captures the vector direction of all light rays hitting its sensor; traditional cameras only capture the color and intensity of light but not the direction. The huge advantage is that you don’t need to worry about focusing when taking an image, focusing happens later on the camera or on your computer.
You can quickly and easily focus on different subjects by simply clicking on a point in the image captured by Lytro. That’s amazing, because so far we were able to adjust every other aspect of a photograph (e.g. exposure, white balance etc.) after it was taken but you were stuck with the manner it was focused.
