I know you are into this sort of cutting edge technology so can you do a blog on camera sensors and how they work. Maybe even take apart old cameras to show how they have evolved over the years.
The breakthrough is a different type of sensor that captures what are known as light fields — basically, all the light that is moving in all directions in the view of the camera. That offers several advantages over traditional photography, the most revolutionary of which is that photos no longer need to be focused before they are taken.
