In the previous blog in the series on Understanding Lighting: from physics to moods, we discussed studio lighting using only one light (the main light). The essence of lighting is to play with light and shadow. The same is of course true if we use more than one light.
Using one bare light produces harsh shadows. This can be overcome by making the light bigger by using an umbrella or a softbox. However, this does not change the darkness of the shadows, it only softens the edges.
To get rid of the darkness of the shadows we need an additional light source. This might be another light, or it might also be a reflector. Note, in a sense a reflector is another source of light, however, a reflector does not produce more light than the light source of the incoming light. So, we cannot fully control it.
Besides the main light there are the following additional lights:
- Fill light These are used to lighten up the shadows. Do not make them too strong otherwise the shadows completely disappear, making the picture flat.
- Background light To create more depth we need to separate the subject from the background. This is done by placing a light behind the subject directed towards the background. If the backdrop is white it is better to use a color, if it is black a white light can be used.
- Rim light To highlight the subject we use a rim light. It is placed behind the subject directed towards the subject. It gives a halo effect around the head and shoulders.
- Hair light Sometimes it is nice to highlight a specific spot of the hair. This is done by placing a small, focussed light at a high position directed towards the hair.
- Kickers They are very similar as hair light, however, they are directed towards a specific part of the subject.
The picture at the top shows a 4-light step bringing most of the above together. One main light on the left, a fill light on the right, a rim light in the rear, and a hair light on the far right. I again used the Virtual Lighting Studio by Oliver Prat of Zvork.
My own experience with a studio lighting setup until now is limited to a main light and several fills, lights and reflectors. In the near future I hope to experiment with the full setup.
This series of blogs on understanding lighting is inspired by Light: Science and Magic by Hunter, Biver, and Fuqua and Sculpting with Light by Earnest.
In the next blog we will discuss the right lighting setup for specific moods.
