    Photography is undoubtedly one of the most important inven­tions in history -- it has truly transformed how people conceive of the world. Now we can \"see\" all sorts of things that are actually many miles -- and years -- away from us. Photography lets us capture moments in time and preserve them for years to come.

    The basic technology that makes all of this possible is fairly simple. A still film camera is made of three basic elements: an optical element (the lens), a chemical element (the film) and a mechanical element (the camera body itself). As we'll see, the only trick to photography is calibrating and combining these elements in such a way that they re...

    The optical component of the camera is the lens. At its simplest, a lens is just a curved piece of glass or plastic. Its job is to take the beams of light bouncing off of an object and redirect them so they come together to form a real image -- an image that looks just like the scene in front of the lens.

    But how can a piece of glass do this? The process is actually very simple. As light travels from one medium to another, it changes speed. Light travels more quickly through air than it does through glass, so a lens slows it down.

    When light waves enter a piece of glass at an angle, one part of the wave will reach the glass before another and so will start slowing down first. This is something like pushing a shopping cart from pavement to grass, at an angle. The right wheel hits the grass first and so slows down while the left wheel is still on the pavement. Because the left...

    The effect on light is the same -- as it enters the glass at an angle, it bends in one direction. It bends again when it exits the glass because parts of the light wave enter the air and speed up before other parts of the wave. In a standard converging, or convex lens, one or both sides of the glass curves out. This means rays of light passing thro...

    Apr 16, 2024 · Focusing. Like your eye, a camera lens sees the world in focal planes. These planes are parallel to the front element of the camera lens and (in most cases) to the sensor. The exceptions are tilt-shift and extremely wide-angle lenses. A lens element must move inside the lens to get a certain plane in focus.

    The main difference between film and digital cameras is the medium that registers the image. Digital cameras have a sensor that stores the image as data, while analog cameras use photosensitive film. A digital camera uses one sensor – once the camera is built, there’s no changing it.
