How to shoot with a long focal length lens

One of the biggest advantages of telephoto lens is snapshot. Many photographers and photographers think telephoto lens is an ideal secret capture or sneak shot. This is thoughtful in shooting distance, but there are also some hidden concerns. The longer the focal length of the lens, the more prone the camera is to shake. And some people exaggerate that a telephoto lens can bring the subject very close at any distance. For example, if you use a 400 mm long lens, it is already in the category of' super long'. In order to make the scene full of painting, you still have to be close to the subject. Specifically, if you shoot a portrait with a 400 mm lens, the farthest shooting distance should not exceed 4-5 meters. For people who secretly take portraits, it is not safe to use only telephoto lenses. The clear range of telephoto lens is very small, but with the wonderful transition, it has the function of compressing the scene and expressing the depth of the scene. This effect is especially obvious when you use a long lens with a focal length of more than180 mm. Before taking a snapshot, you can aim the camera at a place close to the brightness of the subject for metering. If you use a camera with automatic exposure function, you don't need to make exposure compensation, and you can also use automatic exposure mode without metering in advance. With a little practice, you will know how far away you should stand from the subject to take a good picture of him. Don't show too much' interest in photography' when taking snapshots. Then, when you reach the best shooting position, you should quickly hold the camera in front of your eyes, adjust the focal length and press the shutter at the same time. Snapping is the same as shooting other subjects. Practice makes perfect.
