There is only one problem \u2013 you see one thing, and the camera \u2013 quite another, it ruthlessly spoils the whole picture! In this case, however, it is not the camera, it is the ability to work with it. And there is not enough knowledge about what a matrix and what a lens, will have to study a few more concepts.<\/p>\n<h5>Exposition<\/h5>\n<p>The first term that any user who has picked up a professional camera faces is exposure. In simple words, the exposure is the amount of light that falls on the matrix of the camera at the time of shooting. Thus, it is responsible for the saturation of the photo, so first of all you should learn how to work with the exposure.<img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-25578\" src=\"https:\/\/hitmedia.su\/wp-content\/uploads\/2019\/04\/HE_PRjL-QQc.jpg\" alt=\"\" width=\"675\" height=\"462\" \/><\/p>\n<p>To determine the exposure parameters, it is necessary to deal with the exposure meter \u2013 a scale on the screen that shows how accurately the exposure is built. If the runner leaves plus \u2013 there is a lot of light, if the negative \u2013 few. If the slider is near zero, the exposure is correct.<\/p>\n<p>The secret of correct exposure is that to configure it you need two parameters aperture and shutter speed together \u2013 expopair. In the following table you can easily identify the cases in which the ratio of the aperture and shutter speed matched right: cells of the same color located in one diagonal indicate the correct exposure value.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-25581\" src=\"https:\/\/hitmedia.su\/wp-content\/uploads\/2019\/04\/RWvf3bN7qrg.jpg\" alt=\"\" width=\"731\" height=\"512\" \/><\/p>\n<h5>Aperture<\/h5>\n<p>The hole in the lens through which light enters the camera body is called the aperture. It adjusts the brightness of the picture, it can be used to take light pictures even in a dimly lit room and Vice versa. There are 13 aperture values, the higher this value \u2013 the more the aperture is closed, in the picture it is shown as follows:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-25539\" src=\"https:\/\/hitmedia.su\/wp-content\/uploads\/2019\/04\/dia.jpg\" alt=\"\" width=\"684\" height=\"318\" \/><\/p>\n<p>Advises<\/p>\n<ul>\n<li>the two most popular types of photography are landscape and portrait. To shoot a landscape, it is better to use a closed aperture (from f\/8), then it will be clear, for shooting a portrait, an open aperture (f\/1,4 \u2013 3,5) will be more suitable, it will help to make the background more blurred and create the famous <a href=\"http:\/\/100secrets.ru\/chto-takoe-boke-primery-effekta-boke-na-foto\" target=\"_blank\" rel=\"noopener\">bokeh effect<\/a>;<\/li>\n<li>if you&#8217;re shooting a pair, the ideal aperture value would be f\/5.6, and for a group of people \u2013 f\/8, however, in poor lighting, you should use an additional flash light;<\/li>\n<li>in poor lighting conditions suitable aperture value f\/2,8, in bright light at f\/16.<\/li>\n<\/ul>\n<h5>Shutter speed<\/h5>\n<p>Another term \u2013 shutter speed \u2013 means the time during which the camera shutter is open, and the light hits the matrix. Shutter speed is measured in fractions of a second, long shutter speed is used for static images, and short shutter speed is used for dynamic images. However, there is an interesting technique: shooting fast motion with long exposure creates the effect of a blurred trail behind the object.<img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-25582\" src=\"https:\/\/hitmedia.su\/wp-content\/uploads\/2019\/04\/EN-o4gTElak.jpg\" alt=\"\" width=\"683\" height=\"393\" \/><\/p>\n<p>The use of long exposure is justified in two cases: in poor lighting or to create a motion effect (for example, it is better to shoot a waterfall jet at a long exposure). In other cases, it is better to use a short exposure.<\/p>\n<h5>ISO<\/h5>\n<p>Light sensitivity (or ISO) is the speed at which the matrix records information about the amount of light. But the faster the light is fixed, the more graphic information it will lose. The light sensitivity setting is useful if you need certain shutter speed and aperture values in low light. Increasing the ISO in this case will give the necessary exposure, but the fee for increasing the sensitivity will increase the grain of the frame.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-25584\" src=\"https:\/\/hitmedia.su\/wp-content\/uploads\/2019\/04\/zqwXaKWhxfQ.jpg\" alt=\"\" width=\"672\" height=\"389\" \/><\/p>\n<blockquote><p>Tip: even if you shoot in the dark, you should set the light sensitivity not higher than 200-400 to reduce the amount of grain, and if in a well-lit room \u2013 you should bring the ISO to a minimum.<\/p><\/blockquote>\n<p>The ability to work with the basic settings of the camera significantly improve the result of shooting. And with experience, knowledge of settings for specific situations and understanding of the features of your camera will appear.<\/p>","protected":false},"excerpt":{"rendered":"<p><span class=\"span-reading-time rt-reading-time\" style=\"display: block;\"><span class=\"rt-label rt-prefix\">Reading time<\/span> <span class=\"rt-time\"> 6<\/span> <span class=\"rt-label rt-postfix\">minutes<\/span><\/span>The cherished dream has finally come true: you are holding a new camera and ready to\u00a0click everything.
