Aperture, shutter speed and ISO
When you take a photo, you can always leave the camera in automatic mode. Actually, you only need to make the picture. If you want to get a little more out of your photos, a little basic knowledge of the aperture, shutter speed and light sensitivity is not a luxury. In this article we explain these basic principles.
The combination of selected aperture, shutter speed and light sensitivity ensure that a photo succeeds or not. If one of these settings is incorrect, you will get a too dark or too light photo.
In the first instance, the theory behind it might seem a little complicated, but fortunately this is noticeable in practice. What makes it difficult, especially the numbers and terms that are used. Fortunately, you do not have to know too much about it to be able to work faster with your camera.
The shutter_speed determines how long the sensor lights up. The length of time in which the photo was taken. In the machine, your camera tries to keep the shutter speed as short as possible so that every movement in the photo is frozen.
If there is movement in your photo, we call this motion_blur. Motion blur can occur in two ways: your subject moves or the camera moves. A combination of both is of course also possible.
If you want to prevent movement in your photo because you have moved your camera while taking the photo, follow this guideline: the number of millimeters of your lens is equal to the shutter speed 1 / number of millimeters. So with a 100 mm lens you must be at least 1/100 as the shutter speed.
