TO STOP THE TIME
The human eye sometimes can`t see everything, that can be noticed by the camera shutter. We perceive the whole picture, without noticing all of the details, which make up the final image.
We can stop the time and extract from the movement chain the interesting moments due to the camera.
The first method
The easiest way of the stopping the object in the motion – is shooting it on the short exposure. It will be very easy to work in the Shutter Priority mode. Typically, such a mode is indicated by S or TV. To do this, we should choose the lowest possible speed and set the time for which will be "caught" the stop of the object in fractions of a second. In modern cameras it ranges from 1/4000 to 1/8000 sec.
This method is appropriate when there is a lot of light and / or when there is a possibility to use a fast lens. However, if the light isn`t enough or you don`t have the fast lens, it will be necessary to increase the ISO.
If your camera has the automatic ISO control in the shutter priority mode, it will be good to select a minimum position in order to ensure the correct exposure-speed. If there is no such a function, it will be necessary to select the ISO manually in the shutter priority mode.
You can also get the shutter speed in the aperture priority mode, in the manual mode and in the program mode:
the mode M (manual mode): we must use the maximum aperture and expose the possible maximum ISO;
the mode A (AV, Aperture Priority): we should apply the maximum aperture and the automatic ISO setting, for which is set the maximum shutter speed of 1/1000 to 1/4000 of a second;
the mode P (program mode): we have to use the function "Automatic value ISO» and the maximum shutter speed of 1/1000 to 1/4000 of a second.
The second method
If the light isn`t enough and even a high ISO doesn`t help, we will use the flash. The "freeze" can be made even at 1/60 of a second.
The "freezing" of the moving object in this case is due to the reflected flash light. The duration of the light pulse in the flash is very short. If, for example, we set the flash power 1/128 of the total power, the pulse duration will be 1/38500 seconds. If the flash power increases, the duration of the light pulse will be increased too. Thus, you can stop the time at a speed up to 1/40000 second due to the flash.
Such ultra-short shutter speeds aren`t always necessary, sometimes it is enough a 1/200 sec in order to catch the object in the motion.
So let`s summarize. In order to "stop" the time we need a fast shutter speed, the aperture lens, a high ISO, a flash. It is better to shoot the series and then choose the most appropriate photo.
We wish you to take the interesting pictures!
