This document discusses three ideas for photography projects exploring the theme of discovery:
1. Using light drawing to show crowds of people connected to technology symbols like social media logos, representing how technology allows people to discover information. Large photos from high vantage points would show this.
2. Using double exposure to merge photos of people with transparent music note images, representing how discovering new music brings new emotions and makes people want to listen repeatedly. Different colors would represent genres.
3. Using a Harris shutter effect to show a plain face with a single symbol, like a question mark, representing self-discovery as people figure out who they are. Multiple gender photos would show different stories.
