Tips for beginners of digital photography

Liquid crystal display (that's the screen of your camera)

Digital camera screen, the seller's selling point is that the bigger the better, but you have to remember that this has nothing to do with photo quality. It is CCD that determines the quality of photos, marked by 1/x inches. It is like the film of a traditional camera, and the so-called pixels are determined by it.

The most convenient place to shoot with DC is that you can browse the shooting effect at any time. From an economic point of view, it also saves a lot of money on film and development. The effect of browsing on the camera will be better and the brightness will be higher, but when it is transmitted to the computer and viewed on the monitor, it is not the case at all! So sometimes you can't trust LCD completely!

Viewfinder (don't equate it with lcd)

There are also two ways to view a digital camera. One is the optical viewfinder, which is a small hole that you have to stick to your face to see the scenery when taking pictures. The other is an lcd with "entrance" and "exit" functions, which is the display screen. Because consumer digital cameras use so-called paraxial framing, there is a certain error between the picture you see and the actual imaging picture. At present, some card machines simply cancel the optical viewfinder in order to reduce the size and cost. Optical viewfinder is not a dispensable thing. If you take pictures under strong light, no matter how beautiful the screen is, you can't see the beautiful scenery you face. At this time, optical viewfinder comes in handy.

Shutter speed (fraction of exposure time)

Shutter speed has a great influence on the shooting effect. Generally speaking, ordinary DC is fully automatic, the shutter speed is not adjustable, and it is automatically set by the machine according to the data obtained by photometry. According to experience, if the shutter speed of a small camera (that is, a card camera) is slower than1/60s (1/30,115), it cannot be stabilized. If it is a larger camera, the shooting limit will reach 1/30 seconds. Some cameras have anti-shake function, but the effect is not obvious when shooting at night.

The farther away the subject is from the audience (such as shooting the stage), the faster the moving speed (such as shooting the serve in a tennis match), and the required shutter speed should be increased accordingly. If your DC shutter speed is adjustable, it is recommended to control the shutter speed above 1/30 seconds when shooting in a dark environment without a tripod. The shutter is the same as the aperture mentioned below. The bigger the difference between the two ends, the better. In other words, fast enough and slow enough.

Aperture (remember, the larger the number, the less light is transmitted)

Aperture, like shutter speed, is also one of the most critical parameters in photography. The aperture is related to the amount of light entering the camera. Ordinary DC aperture value is also automatic, which is set by the camera according to the data obtained by photometry. Generally speaking, 2.8 is the maximum aperture, that is, the most light enters the camera.

The larger the aperture, the higher the shutter speed, which is especially important when shooting in dark environment and it is inconvenient to use flash. You should also remember that if you want to take a photo with clear close-up and blurred foreground, you must use a large aperture, because the aperture can not only match the shutter to determine the exposure, but also control the depth of field.
