What are the three elements of photography?

The three elements of photography: exposure, focus, and composition. \x0d\ 1. Exposure \x0d\ Control appropriate exposure by focusing and adjusting shutter speed. Most digital cameras can control exposure through autofocus and adjusting shutter speed. This is what automatic exposure photography does (AE). Although it is called automatic exposure, it is not possible to adjust the most appropriate exposure every time. Sometimes the picture may be too dark (underexposed) or too bright (overexposure). When this happens, the correction function is exposure correction. \x0d\ 2. Focus \x0d\ The human eye will automatically focus on the object we want to see, so that we can see everything clearly. The camera lens will focus on the object to be photographed to make it more vivid. The focus is adjusted through the lens, and digital cameras have the function of automatically adjusting the focus. This is the autofocus (AF) function. Although it is possible to focus automatically, it is up to the photographer to decide which point to focus on. \x0d\ 3. Composition \x0d\ The human eye can continuously view up, down, left and right. But photos can only be observed and recorded within the scope of a rectangle. Selecting a very small part of a larger range through the viewfinder or LCD monitor as the picture for shooting is called framing. Recently, cameras have been moving towards automatic exposure and focus. However, no matter how the technology develops, framing cannot become fully automatic. Therefore composition becomes the most important factor.
