I sealed the box with foil so that no light can penetrate inside by taping around. I put one hole with knife for light and placed the cellphone right underneath the hole. Since i could not control the screen of the cellphone, i just started the filming. Finally, i located the box on top of the CHURCH roof and faced to the TEMPLE across.
The result of movie did not show any sigh of colored tilted image of the TEMPLE inside the darkroom box. I thought about the size of the hole on the box was too small to collect the light inside the box.
