My first time lapse approaches the flowering period of the "Iris xiphium" blue violet scented flower, was painted on a recurring basis in the works Van Gogh, named "Lilirio Azul" (Iris germanica) and I discovered thanks to a girl :)
The following link can see a variety of different classes of Iris that there.
Proved necessary to use 2 flowers and 12 days of work (6 record and 6 post-production). We used the back of the camera iPhone 4S and TimeLapse application. Then the photographs were processed in Adobe Photoshop and Adobe After Effects.
