# Creating a Light System

{% hint style="warning" %}
The Light System preset describes the location of you light(s) **relative to the camera sensor**. If you have multiple lights, the Light System preset also describes the order that lights will be triggered in when capturing.
{% endhint %}

1. Click Light Systems on the left side of Marso Measure.
2. Click New Light System in the top right corner.
3. Give your Light System a meaningful name.
4. In order of how lights will be triggered, add the lights in relation to the camera sensor. Be sure to measure carefully with a ruler and input your lights in the necessary axis. Simply click Add Light after you put light information in to the X, Y or Z axes.
5. Once each light is created (or one if you have a one light system), click create. Your light system should now be visible.

{% hint style="info" %}
If you are using a Ring Flash, leave the X and Y axes as 0. Measure forward from the camera sensor to where the Ring Flash sits and input this figure into the Z axis.
{% endhint %}
