1) During planning, the filmmakers created a storyboard using iMovie and Final Cut Pro software to help structure their film about regrets. They received feedback from a BBC editor.
2) In production, they learned camera techniques from a professional cameraman, including the rule of thirds and white balance.
3) Post-production was difficult, but they used Final Cut Pro, Logic Pro 8, and a mixing desk to edit footage and compose music/sounds, which helped structure the film. After revisions, the final version achieved their goals.
