This document discusses three ideas for photography projects exploring the theme of discovery:
1. Using lighting techniques to create images of crowds with technological symbols like phones and tablets, representing how people discover information through technology.
2. Using double exposure to merge photos of people with music symbols, showing how discovering new music can change one's emotions. Different genres would use different color palettes.
3. Using a Harris shutter effect to depict individuals with a question mark symbol on their face, representing people discovering themselves and their identity.
