Surely, the camera obscura was first invented in Baghdad. Alhacaba was the Arab mathematician, born in 965, for in his book “Optical Treaty” shatters the Greek theories prevailing at the time that the light rays are emitted from the eye to the objects displayed. Through experiments and a detailed description of the eyes, says that the thing is totally the opposite: objects emit light rays.
Thus, the observation of this phenomenon gave rise to what later was invented based on the theories of Alhacaba: The camera.
