Stop the time. Short exposure.
When photographing moving objects, it is possible to ‘stop’ them with the help of a photograph and see all the dynamics of movement at ‘stop pause’. Such pictures almost always look very interesting and unusual, since in real time the human eye does not see what can be seen in the freeze frame.
The easiest way to get ‘freeze’ or ‘stop‘ motion in photos is to use slow shutter speeds. Short shutter speed means that the subject is locked for one short moment. The easiest way to achieve a short shutter speed is to shoot in shutter priority mode. This mode is usually referred to as ‘S’ or ‘TV’. For the maximum effect of stopping time, just select the minimum possible shutter speed. For modern SLR cameras, this shutter speed is usually 1/4000 s or 1/8000 s. In this mode, the time in fractions of a second is set, during which the image will be fixed.
Such a simple method works very well when there is a lot of light and / or when it is possible to use a fast lens. For example, in the image above, ISO 100 and F / 1.8 were enough to get a short shutter speed of 1/800 second and freeze the moth’s flight. But most often it’s not enough light, the lens doesn’t have high aperture. Therefore, to achieve the effect of stopping time, you should increase the ISO values. Continue reading
What is ISO and how to configure it
The ISO value is one of the most important settings when shooting, along with such values as shutter speed, aperture, and white balance. ISO is also often referred to as ISO sensitivity, ISO level, or simply the photosensitivity of a matrix or film.
Still, what is ISO in the settings of the camera?
ISO is a parameter indicating the level of sensitivity to light of its light-picking element (matrix or film). Basically indicate the limits of ISO for cameras (cameras). Although, the same parameter can be found not only on the camera, but, for example, on the flash. For a flash, a guide number is usually indicated when using one of the ISO values of 100, or 200. ISO sensitivity is indicated in special units of the ISO system. The ISO numeric expression itself can accept any integer expression from 1 to infinity. For example, on my SB-900, you can set the ISO from 1 (unit) to 12,500, and on my Nikon D40 you can set the ISO value from 200 to 1,600. Continue reading
