Your camera companion: rules for its use

After we got acquainted in the last two episodes of the photography lessons for beginners with the camera from the outside and the inside, and then how to recharge it, we start together a new journey to get acquainted with the rules of its use .

Photography is defined as choosing an element from the many elements that exist around us to obtain the desired image. They are lines, shapes, colors, proportions, and spaces. How to choose to set the frame of these elements, the shots and lights of the image to be captured, and to set the angle of taking the view that will change the direction of strength, importance. relationship things. With regard to these choices, there is no fixed law that the photographer must abide by, and if this law existed, photography would not be considered one of the things in which creativity is possible. On the other hand, there are the laws of sight and vision, And the photographic chemical laws that must be respected, and these laws are what lead to the occurrence of certain effects that must be known to control the technology that allows giving the required image, such as dimensions, areas, and the ratio between them, which changes according to the quality and quality of the lights, and starting with this topic in this series of camera recognition lessons And its uses become ready to take good pictures. And taking a picture takes place through two stages: A - Light: It is the basis of photography. Recording - the illuminated side of things, which you control through the aperture of the lens (the diaphragm). The overexposed light destroys the form, and the underexposed light means that there is no form. From here, the light entering the lens must be adjusted. B - Film: It is the one on which the exposure is imprinted through the lens and through the light barrier, covering that image (we will talk in later issues about the features and uses of films). And now we return to the basic rules for using the camera after we have known it and the capabilities. Speed: The speed of the camera, specifically: the shutter speed of the light barrier, which is to set the required speed for a subject, and it has a numbered schedule and is programmed with the light barrier. Its numbering starts from (1) and goes up to 1000th of a second. In addition to the timing of (b), which enables us to keep the light barrier open as long as you want to enter the necessary light and record the scene. And in some - premium lenses the aperture is much more, since It ranges from 1.2 to 32, but we are talking here about a standard camera model. As we mentioned previously, adjusting the incoming light is done through the aperture of the lens. Photography in cases of speed: shooting a flying plane, a speeding car, or a horse race with a 400 aza film (for example, the measurement - that is, the shutter speed is as follows: speed 1000, aperture 11: cases of strong sun, speed 500 Aperture 8: In cases of low light or shade, for photographing a running person or a moving object: speed 500 Aperture 16: in cases of strong sun, speed 250 Aperture 11: in cases of light light or shade for photographing a normal static scene: Speed ​​250 Aperture 16: In cases of strong sun, speed is 125, lens aperture 8: in cases of light light or shade, speed is 125, lens aperture 4: in cases of very weak light E For flash photography: speed 60 or (7) depending on the type of camera - lens aperture 16 from a distance of one meter Speed ​​60, aperture 11, from a distance of two meters, speed 60, aperture 8, from a distance of three meters, speed 60, aperture 5.6, from fiveMost modern machines are equipped with a self-measurement device called "Posometer" that enables us to know the required ratio of aperture and shutter speed. The last and important thing is to adjust the focus: Numbers located in the front of the lens, which refers to meters or feet, and we can theoretically measure the distance between the subject to be photographed and the camera. If the person or the scene is five meters away from the camera, this number must be set against the signal prepared for that. Otherwise, your photos are out of the required field of vision: Out Focus, another expression blurry (Flu).

This method must be followed carefully, and it may be easier for beginners than searching for adjusting the image inside the viewfinder, given the required accuracy. The latter is done by moving the lens in both directions until the vision is well adjusted when the subject to be photographed becomes completely clear and clear - if we can adjust these dimensions and proportions, we can take some good pictures. And let's try as much as possible to hold the camera well to transform without moving or vibrating when you press the light blocker button, as this has an effect on the quality of the image. Here I recommend stopping the photographer's breathing the moment he presses the light barrier button, provided that his stance is fixed and that opens the legs an appropriate distance from each other. The best proof of this is the footage published here, where the building appears to be ready for explosion. I took these three shots in a static position after I took a deep breath and then pressed the barrier button.

the light . As is clear, the shots look very clear without any shake that causes the explosion: the first shot was taken at 250 f/8.0 speed. The second shot at 1000 f/11. The third shot at 1000 f/8.
