Is there a way out to learn photography?

Photography belongs to the theoretical level of two systems, both in definition and application. By definition, photography refers to the process of recording images with some special equipment. Generally, we take pictures with mechanical cameras or digital cameras.

Sometimes photography is also called photography, that is, the process of exposing the photosensitive medium by using the light reflected by the object. Photography is to use a video camera (video shooting equipment) to convert optical image signals into electrical signals for storage or transmission. A popular explanation is that photography is a static image recording process and photography is a continuous dynamic image recording process.

When you need to use the maximum synchronization speed-usually 1/250s, high-speed synchronization/focal plane flash is a very useful mode. Of course, the synchronization parameter of 1/250s is for high-end SLR cameras, and this parameter is different for different machines. For example, the maximum synchronous flash speed of Canon 5Dii is 1/200s, which is the highest shutter setting.

Beyond this range, the photo effect will not be the tonality that everyone expects, which is also easy to understand. Of course, if you let others do things beyond their ability, but in high-speed synchronization mode, it will not be satisfactory.

Even if you use 1/8000s, as the name implies, you will not be limited by the camera shutter speed in high-speed synchronization mode. This mode is especially suitable for the aperture priority mode of the camera.

In this mode, the flash will emit a series of high-frequency flashes instead of ordinary flashes. This pulsed light ensures that the whole photo can be exposed. However, the price of this working mode is the sacrifice of strength. High-frequency flash will inevitably lead to the loss of light intensity, which will inevitably lead to advantages and disadvantages, so usually the flash needs to be close to the subject.

When the flash is close enough, it can capture moving objects and fill shadows at the same time in the midday sun. Remember! The faster the shutter speed, the weaker the intensity of the flash, so we need to be closer to the subject when shooting. If it is too far away from the subject, the problem of underexposure will inevitably occur, because the intensity of the flash can not reach that distance.
