Single-lens reflex (SLR) camera tutorials are as follows:

1, SLR camera tutorials have the working principle of the camera, the camera's basic to get hold of the method, the aperture shutter and sensitivity of the relationship. First of all, to understand what is a single-lens reflex camera and the working principle of the SLR camera: single-lens reflex viewfinder camera is also known as SLR camera.

It refers to a single lens, and the light through the lens to the reflector, through the reflection of the camera, SLR camera, one of the most important features is that there is a reflector, the light through the lens to the reflector, reflecting to the top of the focusing screen and conjugate the image, through the eyepiece and pentaprism, we can see the outside world of the scene in the viewfinder.

2, master the basic DSLR camera to get hold of the method: DSLR camera holding method properly to help shoot more clear photos, although now the camera basically have anti-shake function, but to ensure that the posture is not shaking is still very necessary. The basic handheld camera posture is this: left hand to the lens, fingers stuck lens, palm resting on the body, left arm and left elbow lightly against the body, forming a triangle.

3, understand the aperture: the aperture is usually located in the center of the lens, it is a ring, you can control the size of the opening of the circular hole, control the brightness of the light during exposure. When a large amount of light is needed for exposure, the aperture's hole is opened wide; if only a small amount of light is needed for exposure, the hole is narrowed to allow a small amount of light to enter.

The aperture functions like the iris of our human eye, controlling the amount of light that can be taken in per unit of time, and is usually labeled f/5, F5, or 1:5.

4. Understanding the camera's shutter: The shutter is a mechanical device in the camera that controls how fast the shutter opens and closes, determining how long the negative receives light. That is to say, in each shooting, the size of the aperture controls the amount of light into the shutter speed to determine the length of time the light into the so-called exposure is completed once the action.

Each of the above numerical units is the denominator, which means that each section of the shutter is: 1 second, 1/2 second, 1/4 second, 1/8 second, 1/15 second, 1/30 second, 1/60 second, 1/125 second, 1/250 second (and so on), and so on.

5, understand the camera's sensitivity: the sensitivity of the SLR camera is a kind of similar to the film sensitivity of an indicator, the ISO of the SLR camera is through the adjustment of the sensitivity of the sensor or the merger of the sensor points to achieve, that is, by improving the light sensitivity of the sensor or the merger of a few neighboring sensor points to achieve the purpose of raising the ISO.
