How the Nature of Light affects the performance of digital cameras — (Part 2) Noise

In the second of two articles I look at another natural phenomenon, photon noise (also known as Shot noise). As with diffraction blur, the problem becomes more serious as the physical size of the sensor is reduced. Whilst this is … Continue reading

How the Nature of Light affects the performance of digital cameras — A new Technical Note

Reducing the physical size of a camera, even if the total number of pixels is maintained, inevitably reduces the quality of the images because of two fundamental properties of light itself. This technical article looks at diffraction, usually explained by … Continue reading
