Ask these questions for every installation

- Standard screen? Front or rear projection?
- Fabric or scrim?
- What color is the surface?
- What are you projecting on? Flat surface or complex geometry? Is it an unusual shape/curved/architectural/sculptural
- What is the environment like?
- Inside or outside? Daytime or nighttime?
- How much ambient light is there? Is it a bright show room, or a dim purpose-lit space? Is there lighting design?
- How will you mount or place the projector?
- Will the venue allow you to drill into the ceiling?
- How will you run cleanly run cables from your command station to the projectors? (More on cable lengths later)
- Where are people (or other objects?) going to be in relation to the projectors?
- Is there a potential for shadows?
- What image size are you trying to achieve?
