Document the surface
Start with sharp images of the entire façade without excessive cropping. Photograph it straight on, from accessible angles and from the intended audience area.
- Full daytime view
- Full view after dark
- Details of windows, cornices and relief
- Available dimensions or plans
- Surface material and colour
Assess light and throw distance
Ambient light reduces contrast. Signs, windows, streetlights and permanent lighting should be identified. Available throw distance directly affects lens choice, placement and required output.
- Distance between façade and technical position
- Visual or physical obstacles
- Possibility of turning off nearby lighting
- Public areas and protected technical zones
Prepare operating conditions
The project must also account for power, weather, safety, permitted sound level, test schedule and circulation around the site. These details are confirmed before technical means are finalized.
