Photography common sense question bank

1. Photography knowledge contest, multiple-choice questions are urgently needed. Thank you.

Canon's top lens is: A.D.B.O.C.I.D.L. German optical equipment brand is: A.Canon B.Samsung C.Kodak D. The meaning of "1:3.5-5.6" on Zeiss lens is: A. Macro is 3.5-5.6b. Wide. Maximum aperture of telephoto end 1: 5.6c maximum aperture of telephoto end 1:3.5 maximum aperture of wide-angle end 1: 5.6d maximum aperture 5.6 minimum aperture 3.5. "Quan Huafu" means that the lens conversion coefficient is: a.0b.1c.

2. A set of questions and answers about photography knowledge

1。

Main light: it is the most important light in the theme. Auxiliary light: used to assist the main light to do some auxiliary lighting.

For example, if I only light one side, the other side of the theme will be darker, so I can supplement it with auxiliary light to show the details of the dark part. 2。

1, light flashing This method uses the light emitted by the internal flash to excite the photosensitive sensor of the indoor flash, so that the indoor flash lights up synchronously when flashing in the camera. This disadvantage is that the internal flash sometimes destroys the light distribution effect. 2, pc line flashing This method requires the camera to have a pc. When in use, the camera and the indoor flash are connected by a special line. The disadvantage is that it is wired and inflexible, and PC terminals on DC are generally cancelled.

3. Wireless Flash Wireless flash is usually used in pairs. The transmitter is installed on the hot shoe of the camera (or can be connected to the PC), and the receiver is connected to the PC of the indoor flash. The effective flash distance is relatively long, there is no connecting cable, which is more flexible, but the camera must be equipped with hot boots (or PC terminal). 3。

There is positive light to measure light with you. Illuminate the left and right sides of the main body with side light, and then turn 45 degrees.

4。 The usage of flash is also elegant, so it is recommended to know it separately.

I don't know what the fifth point means.

3. What are the operational requirements for photography?

Shooting with a camera must first be flat, accurate, stable and even.

This is the basic point of operating the camera. Flat: refers to keeping the camera level all the time during the movement.

If the picture is not kept horizontal, the fixed horizontal and vertical objects in the picture, such as houses, telephone poles and people, will be crooked, which will not only give people uncomfortable visual effects, but also cause psychological instability and anxiety. Adjust the level when shooting with a tripod, and adjust the level state in the viewfinder at any time when shooting with hands or shoulders.

Accuracy: refers to the skills of accurate framing and left picture focusing in sports photography, accurate composition, and attention to focus when shooting. When shaking the picture, you should stand in a good position according to the left picture, and then shake it from the beginning, which can not only ensure the even shaking speed, but also give consideration to the accuracy of composition when shooting.

Steady: It means that the picture should be kept stable and not shaken during sports photography, otherwise it will give people a feeling of dizziness, which will cause psychological anxiety. When shooting in hand, try to hold your breath in one lens or let your body find a relying point and support point. Try to shoot with a short focal length camera lens to reduce camera jitter.

It is difficult to do this, and it is also a basic skill: in the process of sports photography, the camera should move at a constant speed, neither fast nor slow. When shooting with a tripod, it is necessary to adjust the damping of the tripod, master the shooting essentials when shooting by hand, and start and stop the action by increasing or decreasing the force.

Second, the shooting method of the handheld camera The biggest difficulty in shooting a moving lens with a handheld camera is to keep the picture stable. The main factor causing the picture instability is the shaking of the fuselage.

In order to reduce the body shaking when shooting, try to put your feet in a straight line when walking. The best way to avoid shaking up and down is to take smaller steps and bend your legs a little, because all joints of the human body are good shock absorbers.

When shooting with a hand-held camera, you should follow the shooting essentials of "walking straight, bending your legs, taking small steps and relaxing your waist". As long as you practice more and master the shooting skills, you can also take a satisfactory picture with a camera.

In addition, you should try to choose a camera lens with short focal length when shooting. Third, we should pay attention to the key points. First use autofocus, and then practice manual focusing. Fourth, don't shoot against the light. Fifth, start shooting with front, back and side lights, and move as little as possible. In particular, it is necessary to avoid push-pull shooting in drawers. The shots should be grouped and the scenes should not be changed. Don't take too long for a stitch. Just like TV series, one shot at a time.

The basic requirements of camera operation are stability, flatness, accuracy and uniformity: the picture and lens should be stable and not shake. Generally shoot with a wide-angle lens, hold your breath, breathe smoothly and evenly, drive your upper body with your waist, and try to use a tripod and a rail car.

Flat: horizon, sea level, etc. It should be horizontal. Be sure to shoot objects with vertical lines such as trees and telephone poles vertically.

Usually, four levels, pan/tilt meters or image viewfinders are used. Accuracy: The left picture taken should be accurate, and the focus, composition and timing of the left picture should be in place, including accurate white balance, accurate focus and accurate aperture.

Uniformity: refers to the skills of pushing, pulling, shaking and moving, and the speed of the lens should be uniform during the shooting movement. Color temperature: the concept representing the spectral components of a light source.

In a completely closed space, the absolute blackbody is constantly heated. Make its temperature rise continuously.

As the temperature changes, the color of the radiated light also changes. The temperature value corresponding to the chromaticity of white light is the chromaticity value of light.
