As it is known, the snapshot is in front of the film or image sensor in the camera, metal, cloth, etc. It is a mechanical part made of material, it determines the opening and closing time of the curtain at the moment we press the shutter, that is, the time zone, and enables the light reflected from the object to reach the machine in time-controlled manner. The diaphragm is used to adjust the intensity or amount of light that will fall on the film. The phenomenon of falling light on the film at a certain rate using both settings is called exposure. In that case, the state of the light determines the setting of the shutter and aperture settings for the exposure of the film. In moving photo shooting, one of these values can increase or decrease the connections with each other in favor of one or the other by the photographer. Increasing the intensity of the amount of light that will pass through the diaphragm or the exposure time is about increasing the depth of field of the photograph taken or freezing the moving object in the photograph, which is a situation that the photographer will prefer. We can add liveliness to the movements by taking pictures of a moving human, animal, vehicle, a wavy sea or a beautiful waterfall using a low-value shutter.
When we use a low shutter speed in our camera, since the motion will fall on the film in a certain period of time, the still parts of the subject or the parts that are moving slower are clear and the moving parts will leave a mark on the film in the direction of the movement (blurring or blurring). it will gain an aesthetic and poetic phenomenon. What is meant by a low-speed shutter in motion photography is the shutter speed of a moving object, which is below the speed of movement. If we take a photo of a person walking past the camera with a 1/8 shutter speed, the person will be completely blurred, when we take the same photo with a shutter speed of 1/15, the hands and feet (the more mobile parts of the body) are blurred and the other places are clear. will appear as. The photograph we will take at 1/60 shutter speed will come out clearly with the moving person.
Nowadays, the fuzzy (unclear) image of a person running past the machine with 1/15 shutter speed, the one with 1/30 shutter, the hands and feet appear clearly, the other parts of the fuzzy (unclear), the one with the 1/125 shutter value will clearly show the whole subject. While shooting, at a shutter speed of 1/500 and above, any moment of the movement is frozen in our picture. So, to freeze the motion, we will have to use the shutter speed at a value above the motion speed of the object in motion.
As a simple example, when the waterfall photo is taken at a shutter speed of 1/500 and above, while the water particles (water particles) in the air are frozen, we obtain a continuous flowing water mass at the shutter speed of 1/30 or less. Another method used in moving subject photography is the scanning method we call “panning”. Although this method is a little difficult to apply, it is an application that we can produce very different visuals. In this application, we need to be careful about attaching a 50 mm lens to our camera and painting the movement speed of the subject that we will scan. In this application, we have to take our photograph using the shutter value suitable for the movement speed of the moving object. In addition, we should be careful that there are no elements behind the moving object that will negatively affect our position.
We must place our machine on a suitable tripod and make the necessary adjustments for it to move smoothly and comfortably on the horizontal axis. The shutter speed setting is set at a value approximately appropriate or lower for the speed of the object in motion. The moment the moving object enters the viewfinder of our camera, it is followed through the viewfinder, the camera focuses on the subject and moves at the speed of the object, while the shutter is pressed and the photo is taken.Since we will increase the shutter value in order to freeze the movement in the subject we will shoot, the amount of light that will fall on the film will decrease, however, we should not forget that the value of the diaphragm must be reduced in number in order to provide sufficient light.
