The document discusses the use of technology in the production of a thriller film. It describes how a low-quality video camera was used for filming since higher-end cameras were not accessible, and how certain shots like handheld footage of a woman walking down an alley helped establish an unsettled tone. Issues with low lighting required using a torch as an additional light source. Editing software like Premier Pro was used to fix problems like violating the 180-degree rule in post-production. Research online using tools like Google and YouTube helped find influences from other thrillers and appropriate music. Social media like Facebook facilitated communication about the production schedule and tasks. Mobile phones took photos of filming locations.
