Adjust focus-----after taking photograph!
We have often experienced the frustrating experience of taking a photograph and then discovering that the focus was not quite right. The photograph had to be discarded. Now an exciting new development in camera technologies means that you may never have to experience this frustration again-----you can adjust the focus after the photograph has been taken! This allows you to readjust the focus in the photograph on the foreground, medium or background objects.
You can also it so that all objects are in good focus. Both 2D and 3D photographs are possible from the same shot, and you can also take photographs in low light conditions. Normal digital cameras combine all the rays together to one amount of light. The new “light field” camera however records the colour, intensity and vector position of the light rays separately, thereby allowing the data to bee manipulated by the software embedded in the camera. The new camera has been launched in June 2011 by a company “Lytro” based in Mountain View, California and will be available in the shops later this year.
