Today is 3/14, and people throughout the world celebrate two very important events: Pi Day and Albert Einstein‘s birthday. What do Pi and Einstein have to do with photography?
Well, Pi is an integral part of mathematics, be that algebra, geometry, calculus, or differential equations. Without mathematics, signal processing would never materialized. And naturally, modern digital camera’s would not be possible without signal processing.
Einstein on the other hand, explained Photoelectric Effect. A variant of the photoelectric effect is widely used for digital photographic imaging, and in particular in silicon image sensors such as Charge-Coupled Devices(CCD).
So you see, today is definitely a day for celebration for digital photographers all over the world.
