High-quality photographs cannot be obtained automatically with standard settings. Of course, they can be beautiful and interesting for a certain circle of people, but it is difficult to call them art work.
A function such as shutter speed in the camera is required for shooting moving objects, to obtain clarity, sharpness, or, conversely, blur of certain elements (for example, water flow).
So what is a shutter speed? From a technical point of view, this is the period of time during which light rays pass the lens hole, falling on the photosensitive element.
From a scientific point of view, we explained what exposure is. And now let's take a closer look at what it happens and how to achieve the desired effect.
This parameter is calculated in seconds: 1 / 30sec, 1 / 60sec. Often, only the denominator is displayed on the camera, so don't be scared. In compact cameras, the row is displayed as follows: 1.1 / 2, ¼, 1/8, and so on.
In any apparatus for photographing, there is such a function as shutter priority. This means that the aperture is automatically adjusted to the selected value.
Short exposure
Now you know what exposure is. Consider in what cases the above values are used? Immediately point out that a short shutter speed is intended for shooting animals, racing, sports, so that the moving object in the photo does not look “blurry”. The faster the object moves, the less the parameter is set. But remember that in this case, good lighting will be required, since less light enters the shutter. Correct the situation will help the diaphragm, the degree of which we increase in proportion to a decrease in shutter speed.
Slow shutter speed
Such exposure is used in low light and for special effects. But here you definitely need to use a tripod, otherwise the blur will be on the whole photo. If you set high light sensitivity, then expect that in the dark, in the photo there will inevitably be “noise”. You can fix this in the program "Photoshop", but the quality of this is reduced.
The shutter speed is of particular importance when shooting water, regardless of whether it is a fountain or a river. A shutter too fast can create a frozen surface effect, and too long a lack of sharpness. So, for slow rivers and streams, a degree from 1/30 to 1 / 125s is suitable. In windy weather, set the parameter from 1/125 to 1/250. Rapid flows must be removed at about 1 / 1000s.
If you have a high-quality SLR or professional camera, you can shoot the night landscape of the starry sky with an exposure of up to several hours. So you get not only an interesting photo, but also the trajectory of the Earth. Do not forget about photosensitivity, otherwise the noise can be simply unbearable.
Underwater shooting uses short shutter speeds of no more than 1 / 30s, since you are constantly moving, which means that it is likely to get a blurry image.
Now it has become clear to you what exposure is and in what cases it is applied. If desired, interesting effects can be obtained even on advanced compact cameras, and if we talk about professional equipment, masterpieces are provided here. Consider the features of your camera, as well as the shooting conditions, because even sunny or cloudy weather dramatically changes the result.
