Basic Operation of Necessary Reading Aperture and Shutter for Novice

Posted by Adminluckinartist on

This article takes the Canon Starter DSLR as an example to introduce the basic aperture priority (Av) and shutter priority (Tv) operation modes. Through various practical situations, the author teaches you how to operate the Canon DSLR digital monocular camera in your hand correctly. From then on, the wrong aperture and shutter values are no longer set, so as to enhance the concept and strength of basic photography.

If we have a little understanding of the camera body buttons, we have also seen the simple use of various symbols on the camera screen. With these basic understandings, this article takes you step by step to operate the camera from the most important and basic shutter-first and aperture-first modes. The aim is to make you more familiar with the Canon DSLR camera at your fingertips by simply implementing the camera operation steps and instructions.

Tv shutter priority

Tv shutter priority mode is the most important mode for beginners to learn monocular photography, and it is also the first mode to practice. At this time, turn the camera and align Tv with a white line next to it. At this time, the camera will switch to Tv shutter priority mode.

In order to adjust the shutter speed, we need to turn a roller beside the camera shutter release key, turn left and right, and then we can adjust the shutter speed.

When we rotate the wheel with our right index finger, while noticing the information screen of the camera, we can find out the field of shutter speed and see if the shutter speed changes when we rotate the wheel. As shown above, we can see that the shutter speed is 1/200s at this time. You can try to rotate the shutter to practice.

After adjusting the shutter value, you can try to take a few pictures and see if you can find some moving objects as exercises, such as pedestrians, cars and running children. First, you can find the slower main body exercise, then find the larger exercise.

Photographs are taken through the optical viewing window (OVF). The finger moves the roller to adjust the shutter speed and pay attention to the photographic information below. It shows that the shutter speed has been set to 1/320 at present. Every shot must be reviewed before the shutter speed can reach its goal.

As for how to interpret the shutter speed, you can refer to the figure above, if you want to improve the shutter speed, the bigger the number on the right, the more you can catch the main character in the fast action, and freeze it; otherwise, if you want to show the rhythmic sense of the main character, the shutter should be slowed down (such as 1/60) and adjusted gradually according to your needs.

Remember, when practicing shutter priority, the simplest way is to press the shutter repeatedly at different shutter speeds, listen to the sound of the shutter with your ears and look at the pictures just taken with your eyes. It doesn't meet your expectations, such as the main character is ambiguous and unclear, and then turn the turntable to adjust the shutter. Practice repeatedly several times. You'll be more proficient at operating cameras and shutters.

Av aperture priority

Cut the rotating disc of the camera body to AV and align the white sign next to it, that is, start AV aperture priority shooting mode. This mode allows us to adjust the aperture size freely, while the rest, such as sensitivities and ISO, are handled by the camera.

Similarly, the diaphragm value can be adjusted by turning the wheel next to the shutter release key to the left and right.

At this time, use the index finger to pull the roller, while watching the F value on the camera information panel carefully, as shown in figure F3.5 above, that is, the time lap value. With the rotation of the roller, the aperture value will continue to change.

The aperture size affects not only the amount of light, but also the depth of field. It is suggested that a still life be taken. Through different aperture sizes of large aperture (such as F1.8) and small aperture (such as F8.0), we can feel the application of aperture size in photography creativity.

When using the optical viewing window (OVF) to take a picture composition, there is a row of photographic information underneath. The yellow number F2.8 is the time circle value. Through this optical viewing window, you can see all kinds of information needed for photography without looking at the LCD information panel of the camera.

Finally, let's review again. The aperture value is inversely proportional to the actual aperture size. The larger the aperture number F, the smaller the aperture. When we say, "You need to adjust the aperture, your aperture is not big enough", we mean the aperture size of the real lens aperture, not the F value. Don't make any mistakes here.

Beginners practice aperture priority mode, the author will recommend the use of fixed-focus lens large aperture lens (such as Canon EF 50mm F1.8 II) to practice, the effect is more obvious, but also relatively simple, continuous switching large aperture, small aperture to take more pictures, you will know more about the use of aperture in photography, but also more familiar with camera operation.
