How has technology (computer, digital camera, printer) helped you turn your design into a real product?

Computer technology has helped me finish my product by letting me access photoshop which has let me blend pictures and text together to make the advert. I have used the Internet to find the perfect text, the right models and right pictures to make my product become real. I have used a personal printer to keep a copy of my advert, but if I wanted a large quantity printed or printed into a magazine I would go to an industrialized printing press.
