Photography Step By Step

History of Nude in Photography

Andrei — Sat, 18 Feb 2012 15:12:20 +0000

Nude in photography began just while photography was invented and it is not something that started recently as many people believe. Since early 1800, together with the first photographic attempts we had the first nude pictures, either in the form of art or in the form of mapping the naked body to intrigue the human [...]

Portrait Photography Tips

Capturing an image of a person’s face, their entire body, or even a group of people is most commonly referred to as a portrait photo, or portraiture. There are different ways a portrait photo can be shot, whether it is at setup shot with the subject looking into the camera, or in a more documentary [...]

Magnetic Storage Devices

The building blocks of digital images are bits. These can either be zero or one. Magnetic storage devices such as hard disks distinguish a one from a zero by changing the magnetic properties of the disk in that location. The great thing about hard disks is that their capacities are constantly increasing while prices are [...]

Lens Vignetting

In photography, lens vignetting is a reduction of an image’s brightness or saturation at the corners compared to the image center. The word vignette originally referred to a decorative border in a book. Later, the word came to be used for a photographic portrait which is clear in the center, and fades off at the edges. [...]

Camera Field of View

The camera field of view is determined by the angle of view from the lens out to the scene and can be measured vertically or horizontally. Because the aspect ratio differs between formats, the more universal camera field of view is calculated along the diagonal of the scene. A shorter focal length (such as a [...]

Perspective In Photography

Andrei — Sat, 07 Jan 2012 14:48:25 +0000

If you photograph a subject with a tele lens and want it to have the same size on the sensor when photographing it with a wide angle lens, you would have to move closer to the subject. Because this would cause the perspective to change, lenses with different focal lengths are said to have a [...]

Macro

In photographic terms, “macro” means the optical ability to produce a 1:1 or higher magnification of an object on the sensor. For instance if you photograph a aquarium shrimp with an actual size of 21.6 mm so that it fills the 35mm sensor (43.3mm diagonal), the shrimp gets magnified with a ratio of 43.3 to [...]

Distortion

Distortion is a deviation from rectilinear projection, a projection in which straight lines in a scene remain straight in an image. It is a form of optical aberration. Although distortion can be irregular or follow many patterns, the most commonly encountered distortions are radially symmetric, or approximately so, arising from the symmetry of a photographic [...]

Image Stabilization

Andrei — Sat, 03 Sep 2011 14:42:22 +0000

Image stabilization (IS) is a family of techniques used to reduce blurring associated with the motion of a camera during exposure. Specifically, it compensates for pan and tilt (angular movement, equivalent to yaw and pitch) of a camera or other imaging device. It is used in image-stabilized binoculars, still and video cameras, and astronomical telescopes. [...]

Shutterspeed

Andrei — Wed, 24 Aug 2011 22:00:42 +0000

The shutterspeed determines how long the sensor is exposed to light. Normally this is achieved by a mechanical shutter between the lens and the sensor which opens and closes for a time period determined by the shutterspeed. For instance, a shutter speed of 1/125s will expose the sensor for 1/125th of a second. Electronic shutters [...]
