Before lighting a scene we need to know:
- the script
- types of lights
- colour temperature
- use of gels reflectors
The photography below, was taken with a correct camera settings:
The same photo with a colour temperature set to 2500 K. Colour is shifted
to the blue end
of the spectrum:
If we set the colour temperature to 10 000K, the colour is shifted
into the orange end
of the spectrum:
Colour shifts happens when you set the
colour temperature of your camera with
the Wrong end of the kelvin spectrum.
WRONG: not the same as your scene's
colour temperature.
3 Rules
- Set the camera up for the appropriate colour temperature if you want your picture to look normal.
- You can setup your camera at a higher or lower colour temperature if you want a particular cinematographic effect or you are shooting day for night.
- You can mix colour temperatures for creative effects.
Automatic White Balance
The Auto setting helps in adjusting
the white balance automatically
according to the different lighting
conditions, but you can try other
modes to get better results.
Types of lights
- HMI Lights (5600-6000K) - outdoor lights
- Dedo and Redhead (Tungsten) Lights (3,200 K) - indoor lights
Gels
Gels can be used to achieve:
- colour balance (blue gel, orange, green),
- diffusion gels soften the light in order to reduce or diffuse shadows or glare,
- filter - brings the intensity of light down without affecting the colour temperature.
Reflectors
Reflectors are used to reflect light on an object or subject in a situation where:
- there is not enough artificial lights
- artificial light is too powerful
Reflectors have different colour temperature properties. The reflected light can be strong or soft.
Class Work - A short video production
The aim of this workshop was to shoot a short video with a specific mood created by lights.
Our group decided to showcase a young man sitting in a cinema and watching a scary movie.
In order to imitate a specific type of light that can be seen in a movie theatres, we used two dedo lights. One of them was covered with a blue gel, the other with a purple gel. In addition, light intensity was manipulated during a shooting session.
The Nikon camera we used, had a white balance set to fluorescent. That helped us to achieve a desired colour temperature.
