Projection has been strongly in evidence for large-scale screens since the first motion pictures, although the technology has moved forward significantly over the years. A projection system works with a projector shining a light image of the pictures, video or text onto a surface. There are many different types of projector which vary in resolution, brightness, size and cost.
The projection surface can be anything from a high-quality aluminium coated screen material (for high-end specialised 3D projection or cinema work), to a white wall (for simple and basic ambient projections), or even the outside of a building.
We have done some amazing events using these techniques. Typically, the projection screens used for events are a high-gain PVC-based material.
Projection systems can be an effective way of putting over a large image and are essential for presentations, conferences, awards shows and many live events that are held indoors.
The projector itself can be either in front or behind the projection surface; but in either configuration there cannot be any visual or physical obstructions between the projector and the surface. Also the material must allow the light image to transmit in such a way as to allow for clear and bright viewing, which is usually the case with back-projected screen surface, or water screens. One of the most critical factors to consider with projection is the projection distance. This is the relationship between how far the projector is from the screen, and how big the screen is. This has an impact on angle of light from the projector. This can be controlled by selecting the right lens and using zooms. Whilst a range of lenses are available for our projectors, this can be a delicate design consideration as one must consider angles, loss of gain through air particles, amorphic shifts and venue spacing. An experienced projectionist will understand all of these factors.
For the purpose of keeping things simple, measure the width of your screen and double it - that will give you an easy projection distance with which to work. Working to this rule of thumb will mean uou can use standard equipment.
We are able, however, to work with almost any projection configuration using specialized lenses, bounce mirrors, blending and other tools.
