How To Capture A Movement During Photography
To begin with the exploration of the movement in what refers to photography it is necessary, first of all, to take away the paradigm that a photograph is to capture an instant for all life. Even when an image is a static element, the movement can be expressed and even more when processed by an image fixer.
The movement has a direct relationship with time; if the latter does not exist, everything would be immobile. Through time we move, grow and interact. So, how can I express time in a photograph being this an inanimate element?
There are different methods to do it; everything depends on what we want to communicate. In this tutorial, we will see some techniques both to freeze and to make movement flow in a photograph.
In photography, talking about the movement is talking about speed. The shutter of our camera is the one that will allow us to capture a certain time interval of reality. The faster the shot, the smaller the movement that will be captured, and vice versa.
Techniques In Motion Photography
- Freeze Time: One of the advantages of the new digital equipment is that they give us access to speeds greater than 1/2000 (one second between 2000), this allows us to literally freeze a moment of life, to such an extent that we achieve images that represent what the human eye is not able to perceive.
To achieve this type of images you need, first of all, a lot of light. Being shot so fast requires a lot of light so that the sensor of our camera has the possibility to register the scene correctly. Depending on the speed at which the element we want to freeze moves, it will be necessary to configure the speed of our shot. In most circumstances, a speed of 1/1000 (one second among 1,000) will be sufficient to achieve good results. If you have the possibility to increase it, it will always be better.
- Movement in Sports: In sports photography, in most of the occasions, we will look for a highlight. Whether a soccer player kicks a ball, the precise moment a motorist crosses the finish line or just when the batter hits the ball; we must be very alert as these moments can be spontaneous and unrepeatable.
Using continuous shooting ( burst) allows you to obtain a sequence of images from which we can later choose the one that has captured that instant that we were looking for. It is important to use speeds above one / 1,000 (one second between 1,000) to ensure sharpness in the picture. If your camera gives you the option to use a grip with an additional battery, this will allow you to shoot more pictures per second.
- Prolonged Exhibition: While our shutter is open, everything that happens in front of our lens will be registered in the sensor. This is very convenient for certain types of scenes. The fascination to capture the movement of light has been represented for many years in night photography. Capturing light trails, the trajectory of the stars or car traffic is an example of this.
It requires very slow speeds to capture this type of movement. You must use a tripod since the shutter will be open for a considerable time, any movement in the camera will affect the sharpness of your image.
If you are looking to capture the trajectory of the stars, it will be necessary to configure your camera in the bulb option. You will need at least 40 minutes of exposure to capture the movement of the stars.
In the extended exposure, the battery is used up quickly, it is essential to use a grip with an additional battery since during the whole process you will not be able to change batteries in your camera.
The bulb function is used as follows:
- Press the shutter button, and the shutter will open
- When the desired time has elapsed, press the shutter button again, this will close the shutter
- The camera will process the image.
