Exposure
Lighting is the process of film illuminated by light coming from outside the camera by controlling the size of the diaphragm and speed. In terms of lighting, aperture diaphragm determines the intensity of light that passed the film. Shutter speed determine the period of transmission of light.
There are several things you can do to determine the appropriate combination of aperture diaphragm with speed.
One of them by selecting the aperture priority. That is, the photographer can choose how large aperture diaphragm that will be used. Each of the selected diaphragm aperture will make the outcome different images. When the photographer choose to use a high shutter, then it is useful to stop the action. while the low shutter will make the action run. As for taking pictures in places with less light then to overcome them by the photographer is using high speed film. For example, ISO 400, 600, 800 or ISO 1600.
How to measure the lighting is usually available in every camera. To measure the light to be consistent, we can mensiasatinya by measuring the palm of the hand or bring our camera about 30 cm from the object. So, we'll have this lighting accordingly. To get good light in a photo shoot usually we would choose the photograph on the hour 08:00 to 10:00 and 16:00 to 18:00. usually in this time, the light in good condition, and not too hard.
In lighting there are some techniques that should be considered, including:
- Lighting the front: The source of light coming from the front of the object. This light will produce a flat image.
- Lighting the back: The source of light came from behind the object. With these light sources such as the object that we take into shiluette (black). Shooting with the light source from behind do if we want to make a photo shiluete.
- Lighting Side: Photographs by wearing light source from the side to make objects that we take will seem firm.
