The sensor is made up of millions of photosensitive cells arranged in rows and columns. For example, a 24Mpx sensor usually has an array of 6000 x 4000 photosensitive cells. We will initially assume a monochrome sensor (which only generates black and white images). Each cell collects an amount of light, which corresponds to that … Read more
Sometimes the analogy is made with the world of analog photography and is colloquially called digital negative, referring to the opposite of the film. I’m not a big fan of this analogy, but in a way, RAW and negative share some similarities that we will see later. How does a digital image sensor work? In … Read more

When the shot occurs, the mirror is raised, rotated upwards so that light can reach the electronic sensor (or the … Read more
The photograph is a relatively expensive hobby. Especially the initial investment in a camera. The cameras’ electronic systems are technologically advanced, and the optical elements (lenses) are very complicated to design and manufacture. Both the cameras and the lenses are expensive, and as soon as we go to medium and high ranges, prices skyrocket. One … Read more
