What are the photography skills for daily shooting?

Whether you can shoot a good work depends not only on good photographic equipment, but also on the patience of the photographer. The following are some common photography techniques that I carefully recommend for you, hoping to help you.

Photography skills

First, use a tripod.

The camera must be mounted on a tripod to prevent the camera from shaking when shooting. Try to keep the camera close to the subject, and be careful not to introduce unnecessary shadows.

Second, use reflective cards when necessary.

Wrap it in a white card or aluminum foil to reflect the light on the object and illuminate the shadow on the object. Be careful not to let this card appear in the shooting range.

Third, use cable release.

Even if you have installed the camera on a tripod, if you press the shutter carelessly, it may still shake the camera, so in order to avoid this situation, I suggest you use cable release.

Step 4 Use a black or colored background

When shooting, when the background of the object is black, the shot image can be made to look the clearest. You can also use a fuzzy background, especially when the color of the subject is very strong.

V. Focus tracking

Although it is not necessary for shooting, the focus track is a good auxiliary device, which can help you take good close-ups. The focal track can make the camera move along the X-axis and Y-axis in very small increments, and can accurately control the camera position and the depth of field of the picture. It is very troublesome to move the triangular bracket to the ideal position.

6. Be patient.

There are many uncertain factors in the process of photography, so sometimes some changes in external conditions will affect the photographer's mood. At this time, you'd better choose another time and shoot later to get a more brilliant side.

Seven, make good use of composition

There is no doubt that the quality of photography and whether martial arts reach a certain level are inseparable from composition. At present, in the process of composition, we can make a meaningful work by using it reasonably and resolving it through our own skills.

Photometric principle

Early cameras didn't have a metering system, so photographers needed to choose the aperture coefficient and shutter opening time according to the estimation of the light at the shooting scene. This method requires photographers to have some practical experience, according to different light.

Appropriate exposure parameters-different combinations of aperture and shutter. Moreover, it is troublesome to decide in advance whether to choose the aperture first according to the depth of field or the shutter first according to the motion state of the subject. The error of estimating the exposure index only by human eyes may be very large. Moreover, the light in nature often changes very quickly. When you choose exposure parameters, the light may change at the moment you press the shutter, so the success rate of shooting at that time can't be very high. Fortunately, people mainly took black and white photos at that time. Black-and-white film has a large tolerance, allowing a large exposure error. Moreover, it can be corrected in the post-production of photos. With the popularization of color film, the requirements for camera metering system are getting higher and higher. The tolerance of color film is relatively small, and the tolerance of color reversal film is even smaller, which requires more accurate exposure. Because of the mistake of exposure, it will seriously affect the color reproduction of photos. The method of estimating exposure index by human eyes is too backward to meet the requirements of accurate exposure of color films.

In order to improve the success rate of shooting and meet the needs of color photography, hand-held exposure meter came into being. Using the exposure meter, the exposure combination of aperture and shutter required for correct exposure can be obtained more accurately. However, the detection range of the hand-held exposure meter is not necessarily the same as the angle of view of the lens used by the camera, especially for SLR cameras with interchangeable lenses. Therefore, there will be some errors in photometric values. In addition, after measuring light with an exposure meter, the aperture and shutter are manually adjusted. The whole operation process is long and the shooting efficiency is very low. It was not until 1962 that internal metering was realized for the first time on a Pentax 35mm SLR camera in Japan. Internal metering, also called TTL metering, is the prefix of three English words Through The Lens, which means metering through the lens. That is to say, the exposure meter is installed inside the camera, and the detected light passes through the lens of the camera before reaching the metering element of the metering system. It is a schematic diagram of metering in SLR cameras, and points A and B are the locations where metering elements are usually installed. The detected light reaches the metering system through the lens, which is basically consistent with the light reaching the film surface, so the internal metering system can get accurate metering values. And in this way, no matter what lens the camera changes, the metering system will always detect the light incident through the lens, and there will be no problem that the exposure meter and the lens have different angles of view.

Use of internal photometry

There is another problem that needs special attention when using the camera's internal metering system for metering. This is the basis of the camera metering system, which measures light according to 18% neutral ash. Therefore, when shooting objects with different tones, if you want to restore the original tone of the object correctly, you should also consider it when measuring light. Sometimes, the camera's photometric data is just for reference, and photographers have to make their own choices. For example, taking a snow scene in winter, if the exposure is completely according to the index given by the internal metering system of the camera, the color of the snow may be gray, not white snow, as shown in the middle picture. This is because the camera's metering system regards snow as 18% medium gray when metering, so the snow exposed according to the camera's metering system is not white. At this point, if the exposure is compensated and increased a little, the snow will be white.

The internal metering system of the camera provides great convenience for photographers, and various metering methods allow photographers to create wholeheartedly. The automatic exposure function allows people to focus on how to take good photos without worrying about choosing exposure parameters. However, if you want to take high-quality photos, you need a photographer to be familiar with the characteristics of the internal metering system of your camera. More importantly, you should be able to use all kinds of photometry methods correctly and know something about actual shooting.
