How we construct our family identity based on the pictures created by our ancestors?

Going through my grandfather's stuff I found old slides and 8mm films about my family. Then I realized that we shared the same passion: photgraphy and the creation of a family-picture.
Since then, I proposed to myself making a research about my picture-history's family, combining and overlaping this discovered archive with my own photographies, videos and illustrations. Mixing this inherited family's album with music, sounds and animations, I try to project a picture-identity for the next generations.
