Stop the time. Short excerpts

This article describes how to stop time ’in pictures with the help of a camera.

When photographing moving objects, it is possible to ‘stop’ them using a photo and see the entire movement dynamics on a ‘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 on a still frame.

The easiest way to get the “freeze” or “stop” effect on photos is to use short shutter speeds. A short shutter speed means that the subject is captured for one short moment. The easiest way to achieve a short shutter speed is to shoot in shutter priority mode. Usually, this mode is referred to as ‘S’ or ‘TV’. For maximum effect, stopping time is enough to choose the minimum possible shutter speed. For modern SLR cameras, this shutter speed is usually 1/4000 s or 1/8000 s. In this mode, set the time in fractions of a second, during which the image will be captured.

This simple method works very well when there is a lot of light and / or when it is possible to use a high-aperture lens. For example, in the photo above, ISO 100 and F / 1.8 were enough to get a short shutter speed of 1/800 seconds and freeze the flight of a moth. But more often than not, the light is low, the lens does not have a high luminosity. Therefore, to achieve the effect of stopping time, you should increase the ISO values.

Stop motion
The stoppage in this case occurred due to an increase in the ISO sensitivity to a value of 1250. In this case, a ‘dark’ lens with F / 5.6 was used.

It is easier to simply freeze motion if the camera has an ISO auto-control function in shutter priority mode. For example, on all modern Nikon CCDs, you can set the auto ISO function for P, A, S, M modes. In the shutter priority mode, the camera will select the minimum ISO sensitivity value to provide the desired exposure at a short shutter speed. For example, in the photo below I shot in this mode.

Auto ISO
Auto ISO. On the camera, I set the shutter speed to 1/2500 seconds, and the camera independently picked up the aperture and ISO value so that it was possible to get a properly exposed image with such a short shutter speed

But if the auto ISO functions for P, A, S, M modes are not present, for example, as on my Canon 350D, it is enough to manually select the ISO value in the exposure priority mode so that the exposure meter shows zero deviation from the norm.

Dove in flight
Dove in flight. Manually selected ISO 1800 for correct exposure when using a very fast shutter speed of 1/8000 second.

The effect is most pronounced when using the shortest shutter speeds that are permissible on the camera. For example, 1/4000 s or 1/8000 s.

You can get a short shutter speed in both aperture priority mode and in manual mode and in program mode. I can easily use all 4 advanced modes to achieve a short shutter speed, but this requires a very long description. In short, I’ll say that it’s very easy for me to get a short excerpt:

In M mode (manual mode) using maximum aperture and auto ISO
In A mode (AV, aperture priority), using the maximum aperture and automatic ISO value, for which the maximum shutter speed is set from 1/1000 to 1/4000 seconds.
In mode P (program mode), using the auto ISO function, which has a maximum shutter speed of 1/1000 to 1/4000 seconds.
Sparrow in flight at fast shutter speed
Sparrow in flight at short exposure. The aperture value for some reason is not displayed in EXIF.

Another simple way to stop time is to use flash. With a flash, it is very easy to stop moving when shooting in low light conditions. You do not need to use short shutter speeds of the camera, even 1/60 of a second is enough. This is due to the fact that the freezing of a moving object occurs due to the reflected light of the flash. The duration of the light pulse of a flash is very, very short. For example, my Nikon SB-910 external flash has a light pulse duration at 1/1 full power equal to 1/880 second. And if you set the flash power equal to 1/128 of the full flash power, then the pulse duration will be only 1 / 38.500 seconds. With increasing flash power, the duration of the light pulse increases. Since when shooting in low light conditions, virtually all of the light comes only from the flash, the flash plays a crucial role in creating the picture. This means that using a flash, you can freeze objects at flesh speeds of up to 1 / 40,000 seconds. This is a very short time, with the help of this technology, you can make simply incredibly interesting images with a stop in time.
