Image resolution

All digital photos fundamentally consist of countless, interconnected pixels. These tiny pixels contain information about colour and brightness. When an image is captured, the camera’s image sensor stores individual detected pixels and projects a corresponding image. The resolution indicates how detailed an image can be reproduced or how many pixels it consists of. Different minimum […]

AF – Autofocus

Since the 1970’s, there have been attempts to develop cameras with autofocus capability. Besides camera shake, using the wrong focus is a main cause of a photo appearing blurry. Since about 1985, automatic SLR cameras have played an important role in the world of photography. Currently, the speed and precision of the autofocus is so […]

MF – Manual Focus

Ambitious hobby photographers can’t but help themselves to try their hand at adjusting the sharpness of the photo themselves. Technical utilities can be used to assist in this endeavour. When using a DSLR camera with a live view, a central portion of an image can be enlarged and later perfectly focused after some manual adjustments. […]

Focusing

The exact distance setting used to photograph an object is known as focusing. The object should be focused by adjusting the camera as well as the lens. Often, people don’t really pay attention to using the right focus when photographing, but by keeping the amount of focus in mind when taking pictures, you can widen […]

Camera Flash

Camera Flash

In photography, any method of producing better lighting of the object you’re photographing by using an instant and short burst of light is known as a flash. Using a flash makes it possible to take pictures with sharp quality even in poor lighting conditions. Most cameras come with an integrated flash or a port capable […]

A lens acts as an optical system that generates an image of an object. The simplest form of a lens is made up of a collecting lens, which gathers together rays of light and projects them onto an image plane. Modern camera lenses, however, are made up of multiple lenses and mirrors. Some camera lenses […]

All lenses with a focal length less than 50 millimetres are classified as wide-angle lenses. If a lens has a focal length of 20mm or less, it’s classified as an ultra-wide-angle lens. The most extreme form of a wide-angle lens is the fisheye lens. These lenses have a focal length of less than 16mm and […]

“Tele” comes from Greek and has the meaning of “far.” Telephoto lenses enable the photographer to photograph objects “up-close” from a far distance. A telephoto lens essentially functions the same way a telescope does. In comparison with normal lenses, telephoto lenses have a higher focal length. A lens is considered to be a telephoto lens […]

Macro Lenses

Macro Lenses

Using a macro lens makes it possible to achieve a high image ratio. The reproduction ratio describes the relationship between the actual size of an object with the depicted size on the photo sensor. With a ratio of 1:2, for instance, the photographed object is twice as large as it is depicted on the sensor. […]

Focal Length
Technology

Focal Length

/

The focal length describes the distance between the lens and the focus. A focal length is given in millimetres. The larger the focal length is, the larger the object will appear in the photo at the same distance. It is also an expression of the image magnification at a given distance. The focal length directly […]

Aperture
Technology

Aperture

/

The aperture regulates the amount of light that hits the sensor. If the aperture is fully open, a lot of light is allowed through. The more closed the aperture is, the less light is allowed through to hit the sensor. The aperture is mostly a mechanical system that consists of circularly arranged blades which slide […]

Objective Lenses

Objective Lenses

Objective lenses (from now on referred to as just lenses) are translucent objects that focus light beams through refraction. The first theories of optical magnification by using curved lenses came about a thousand years ago. These theories were further developed in the 12th century. At this time, the reading stone was created, which was placed […]

The Pinhole Camera

The simplest and most likely oldest optical device used to generate an image of an object is the pinhole camera. The famous Greek philosopher and naturalist Aristotle first described the construction and operation of a “dark chamber” over 2000 years ago. In this dark chamber, a small opening was made for light to pass through […]

A camera that produces a developed photo directly after snapping the picture is called an instant camera. In classic analogue instant cameras, a stack of paper with a light-sensitive surface is used instead of normal film. This paper contains the chemicals necessary for the development of the photo. When taking the photo out of the […]

A comparatively low weight and compact size are two of the biggest advantages of compact cameras. Compact cameras are available in a wide range of capabilities and prices from manufacturers such as Canon, Nikon, Panasonic, and Sony. Unlike DSLR and system cameras, compact cameras are equipped with a fixed lens. This camera class also includes […]
