Sample text

The four main categories of camera design are: direct vision/rangefinders (both compact and advanced models), twin-lens reflexes, single-lens reflexes and view cameras, all of which are described in more detail in Langford’s Basic Photography. When considering purchasing or using a camera for serious photography, however, what is more important is the camera system. The system encompasses not only the design of the camera, but the level of sophistication in design, the degree of control by the user, the way in which it is used and the type of accessories available with it.

Amplifying the signal also amplifies the noise levels and this may show up as coloured patterns in flat areas within the image. Exposure and the image histogram: This is a process of shifting the output values by amplification of the input signal, to ensure that the maximum range of output values is produced, ideally without clipping the values at the top or bottom of the range. The actual exposure measurements are taken through the lens as for a film camera and image processing takes care of the rest.

When exposed to light, it produces a small amount of electrical charge proportional to the amount of light falling on it, which is stored, transported off the sensor, converted into a stream of binary digits (1’s or 0’s, hence the name ‘digital imaging’), and written into a digital image file. The process is a complex one, and the structure and operation of the sensor is covered in more detail in Chapter 6. There are many fundamental differences between film-based and digital imaging, not least that where a frame of film both captures and stores the image, and is therefore not reusable, a digital sensor captures the image, but it is then transported away and stored as an image ‘file’ somewhere off the chip.
