تبدیل اتاق خواب به دوربین عکاسی

Want to turn a room into a camera obscura? Nick Marshall, manager of exhibitions and programs, shares how you can do this with objects found around your home! PDF instructions available at eastman.org/activities.

A camera obscura is an optical device that makes a projection from the light entering a darkened space through a small hole (or aperture). Inside the camera obscura, viewers will see whatever happens to be in front of the aperture, the only difference is that the projection looks upside down and backwards. Before photography, the camera obscura was used to more perfectly illustrate images, as one could trace what appeared projected on the wall.
