Understanding camera property
Shutter Speed
•The speed of the shutter. The value of the speed at which the camera shutter opens and closes. That is, a value that controls how long the camera is exposed to light.
•When the shutter speed is fast, the exposure of the light decreases and it becomes dark,
•Slow shutter speeds increase the exposure of the light, making it brighter.
•Of course, when the light is abundant, increasing the shutter speed does not always darken. (Shutter speed 500 means the shutter opens and closes for 1/500 second. Shutter speed 2 means the shutter opens and closes for 1/2 second.)
•The faster the shutter speed (the smaller the value), the more vivid the picture can be.
ISO
•ISO is a measure of how sensitive the camera is to light.
•In general, when the ISO value is high, it is sensitive to light and brightens. However, noise occurs at the same time. (If it is too high, noise will be severe like ISO 25600 in the picture below.)
Aperture (F Value):
•Value for how long to keep the camera aperture open for incoming light. In other words, a value that controls how wide the light is exposed.
•When the F value decreases, the aperture opens a lot and the image becomes brighter. When the F value increases, the aperture opens smaller and the image becomes darker.
•For reference, F value = focal length / effective diameter. The effective diameter increases as the F value decreases, and the effective diameter decreases as the F value increases.
•However, the F value cannot be lowered unconditionally, because the depth varies depending on the F value. The lower the F value, the shallower the depth.
