This is a study on book design. My inspiration comes from Ken Kitano’s photographic works, Our Face. He took many fascinating multiple-exposure pictures of people. And I used a similar way to explore a topic–“ChangingImage”. I printed different portraits of different people with the same posture on transparent plastic cards, with one person on one card. The transparency of the person on a card is only 5%. When the cards are stacked up and the light goes through the stack, a whole new image is formed out of the combination of 21 people’s images. Interestingly, if the order of the cards is changed, a different image is produced. The people on the cards are like genes, which are capable of forming different images depending on how they are arranged. That is what I call “ChangingImage”. A traditional book can be read only page by page, and nothing can be read after the book is closed. On the contrary, the book I made presents a new image when it is closed. What’s more, different results are shown when the order of the pages or the transparency is altered. This is a meaningful method to be used in exploring the book design.
