The process of how other lighting effects impact laser lighting can be difficult to understand. We hope by writing this blog we can make things clearer and give you a better understanding of how lasers will look in your event space. Before a show at the Gramercy Theater in New York City, we were able to take a few snap shots of the same laser effect with different lighting going on in the background.
First, let’s determine what exactly you are looking at. There are two 2 Watt Green (532nm) laser projectors displaying the same "finger-beam" laser effect. One of the laser projectors is placed on the left side of the stage and the other is placed on the right side of the stage. We positioned the laser projectors so that the effects that they produce cross in the center of the theater. Haze (or fog) is always a must-have when putting on an aerial laser show, since the laser light needs to interact with particles in the air to become visible.
The laser effects featured in the pictures above, from left to right, look as if they are getting brighter. In reality though, they are the exact same laser effect with the exact same power level. So then why does it look like some lasers are brighter than others? Simple: It's all due to the other lighting effects going on, on the stage.
The first picture is the most difficult to see the laser effects. On stage there are 8 white light moving heads. In the second pictures only 4 white light moving heads are turned on, making the laser effects stand out a little bit more than the previous. In the third picture all of the white light moving heads are turned off and only two gobo lights are turned on (images on the floor). This makes for a darker background and a better atmosphere for the laser effects. Finally, in the fourth picture no other lights are turned on directly behind the view of the laser effects. Clearly you can tell the difference between this picture and the previous ones.
One of the first steps in the LaserJockey® process is to find out about the event space. On-stage lighting effects weigh-in heavily when we decide what laser power will be sufficient for your event space.
