Photographic terminology

Image depth

The front boundary of the depth of field and the back boundary of the depth of field respectively * * * the distance between the two imaging planes of the yoke. Image depth corresponds to the depth of field, and the greater the image depth, the greater the depth of field.

The standard for determining the depth of field: 135 The diameter of the blur circle allowed by the camera is generally 1/30 mm, that is, 0.033mm..

Hyperfocal distance:

When the lens is focused at infinity, the scene at infinity forms a clear image, and at the same time, the object at a certain point at a limited distance can reach a clear standard, and the object near this point is blurred, so the distance between this object and the lens is hyperfocal distance.

Focal length:

The distance from the center of the lens to the focus. The unit of focal length is usually expressed in mm, and the focal length of the lens is usually marked in front of the lens, for example, f=50mm (is this what we usually say? Standard lens? , because its viewing angle is the same as the human eye, it is called a standard lens). The focal length of 28-70mm (our most commonly used lens) is most suitable for taking portraits, 70-2 10mm (telephoto lens) and so on.

Aperture:

A device that controls the amount of light passing through a lens. The aperture is represented by f, including f 1.0, f 1.4, f2.0, f2.8, f4.0, f5.6, f8.0, f1,f 16 and f22.

Shutter (shutter)

Device for controlling exposure time. Shutters can generally be divided into curtain shutters, lens shutters and steel shutters. Among them, curtain blinds can be divided into vertical curtain blinds and horizontal curtain blinds. Steel shutter can reach higher speed (the highest shutter speed can reach112000 seconds or more at present). Generally, the highest speed of the inter-mirror blade shutter does not exceed 1/500 seconds, but the biggest advantage of the inter-mirror blade shutter is that the noise generated during shooting is extremely low, which is very conducive to sneak shots and can realize synchronous flashing within the full speed range.

Shutter speed (shutter speed)

Opening time of shutter. It refers to the time (exposure time) when light sweeps across the film. For example,? 1/30? Indicates that the exposure time is 1/30 seconds. 1/60? It means that the exposure time is 1/60s, and the shutter speed of 1/60s is twice that of 1/30s. The rest and so on.

Note: Some materials refer to shutter speed as shutter time. The two names are different, but they mean the same thing, both referring to the shutter opening time.

depth of field

The relatively clear range of the image. The depth of field depends on three factors: the focal length of the lens, the distance between the camera and the subject, and the aperture used. The relationship between depth of field and the above three factors is: the longer the focal length, the shorter the depth of field; The shorter the focal length, the longer the depth of field (for example, under the same aperture and distance, the scene of 28mm lens is far greater than that of 70mm lens); (2) The closer the distance is, the shorter the depth of field is, and the farther the distance is, the longer the depth of field is (for example, under the same focal length and aperture, the subject scene at 10 m is far greater than the subject depth of field at 1 m); (3) The larger the aperture, the shorter the depth of field, and the smaller the aperture, the longer the depth of field (for example, under the same focal length and distance, the scene with the aperture of F 16 is far greater than the depth of field with the aperture of F4).

Depth of field preview:

In order to see the actual depth of field, some cameras provide a preview button of depth of field. Press the button to reduce the aperture to the selected size, and the scene you see after shooting is the same as that recorded on the film (memory card).

composition

The name composition comes from western art, and there is a course called composition in western painting.

The composition of famous names is also called layout or quotient position in Chinese painting theory. In other words, photographic composition is transformed from artistic composition, which we can simply call framing.

Whether it is the layout in Chinese painting or the framing in photography, it only involves part of the composition, and it cannot contain the full meaning of composition. Therefore, it is more scientific and accurate to use the word "component" uniformly.

Sensitivity (ISO)

Indicates the exposure speed of photosensitive materials. Unit use? Degree? Or? Settings? To express, for example? ISO 100/2 1？ Represents a film with a sensitivity of 100 degrees /2 1 The higher the sensitivity, the more sensitive the film is (that is, the less light is needed to shoot the same photo normally in the same shooting environment, that is, a higher shutter or a smaller aperture can be used).

Color temperature (color temperature)

Different pigments contained in different kinds of light are called. Color temperature? . What is the unit? k？ . The color temperature we usually use is 5400 K-5600 K; The color temperatures that light types A and B can adapt to are 3400K and 3200K respectively. Therefore, different types of films should be selected according to the subject and environment, otherwise there will be color cast (unless the color temperature is corrected by color filter).
