If you use an SLR camera, making the right settings is essential to get a good exposure. On most SLR cameras, you will find in the viewfinder an indicator connected to a cell to properly expose your photos. By playing with the settings, you can expose your photos well.
3 SETTINGS ARE IMPORTANT TO KNOW.
THE EXPOSURE SPEED :
The speed determines the rendering of the movement. It must either freeze the action or give the impression of movement.
It corresponds mechanically to the opening speed of the curtain:
- The slower the speed, the more light you will have, but the less movement you will have.
- The faster the speed, the less light you will have, but the more motion will be frozen.
THE OPENING :
The aperture in photography is simply the diameter of the hole in the center of the diaphragm.
By opening the diaphragm more or less, it is possible to control the amount of light that passes through the lens to reach the sensor. Thus, we can logically say that :
- A large aperture lets in a lot of light.
- A small aperture lets in little light.
THE ISO SENSITIVITY :
The ISO sensitivity corresponds to the sensitivity of the film to light.
A film with low ISO (50-100-200) will be less sensitive to light than a film with high ISO (1600-3200).
The ISO of the film is chosen at the time of purchase. It is not possible to modify this value.
We will choose the ISO value according to the exposure of our scene, if there is a lot of sun, we take film with a low ISO and vice versa.
