What safety should I pay attention to when taking pictures?

In digital cameras, snapshot mode has become a selling point in the function list, and it appears as frequently as "fps". Many people expressed their willingness to buy digital cameras with snap mode.

In the snapshot mode, the continuous shooting speed and continuous shooting times of a digital camera depend on the memory size of the camera, the size of the picture and the compression degree of the image. Before storing and processing images with a memory card, a cache is usually used to temporarily store images. Professional cameras usually have a large cache and can store a large number of high-resolution and uncompressed pictures, while general users have a small cache capacity and limited ability to store pictures, mainly because the number of stored pictures is small and the quality of uncompressed images is poor. However, the working principles of the two cameras are similar, and they are both very practical.

It should be noted that repeated use of snapshot and continuous shooting mode will take up a lot of memory space, unless the resolution of the image is reduced through the LCD screen, so it is recommended that you buy a large-capacity memory card.

Continuous shooting mode

Most of the photos in publications are in continuous shooting mode, such as geological photographers, who take many photos in continuous shooting mode and then choose the most satisfactory one.

Capture mode has two purposes. One is to take a series of photos quickly, and then choose the most satisfactory one from these photos. Second, when there is no other way, it can accurately capture a short moment.

In fact, many digital cameras have shutter delay (the time interval between two shots). Use this? Later, the camera can determine the white balance, focus and calculate the exposure settings. However, this time may also cause you to miss the best shooting opportunity. At this time, the snapshot mode can come in handy!

Choose the best picture

The use of snap mode needs to be set in advance, such as keeping the camera stable, determining the focal length and setting various functions.

Continuous shooting mode is mostly used to shoot moving objects, such as the puppy in the picture below. With this mode, you can easily choose the best one from a series of pictures.
