3D projection on the side of the Beurs van Berlage in Amsterdam
Light is an important factor in order to achieve a beautiful projection. Too much light will have a negative effect on the contrast and colors of a projection. It is therefore important to take into consideration which other light sources are near the buildings while choosing the area for projection. If there are some adjacent buildings that have lots of lights it is sometimes possible to cooperate and arrange for the lights to be switched off during a projection. In some areas it is necessary to switch off the community lights, cooperation from the local governments can be of great help. The surrounding lights determine how many projectors are needed for the actual projection as well as the light intensity.
A minimum distance of 35 to 40 meters is required between the building and the projector in order to get optimal results. Naturally this distance needs to be free from any obstacles such as trees, lamp poles, tram lines etc.
