Katie Pearl gathered extensive audience feedback throughout the process of creating her advanced portfolio, including feedback on her documentary ideas, edited footage, documentary title and message, and ancillary products like a documentary advert and magazine listings. She used questionnaires, focus groups, and messaging apps to collect this feedback at various stages of production. The feedback helped her determine the focus of her documentary, improve her editing, ensure her products adhered to conventions, and learn what her target audience preferred. It enabled her to make beneficial changes to her work and create the most effective final products.
