A drone formation is usually held at the opening ceremony to give the scene a stronger sense of ceremony and to leave disseminable photos and video material for the event. The pattern design should serve the opening theme, rather than pile up all the information you want to display.
Brand logo and project name
Logo is the most common content in opening events, but complex logos need to be designed to be flyable in advance. When lines are too thin, details are too many, or colors are too complex, you may need to simplify your expression.
Opening greetings and countdown
Contents such as auspicious opening, grand opening, city name, countdown, etc. are suitable to be used in conjunction with the stage opening, ribbon cutting or unveiling to help the audience quickly understand the theme of the performance.
Product outline or industry symbol
If it is a brand launch or project launch, you can consider product outlines, building outlines, industry icons or brand keywords. The number of patterns should not be too many. It is recommended to retain a core image that is easiest to photograph.
