History of Camera “Photography” is derived from the Greek word photos meaning light‚ and graphein meaning to draw. The word was first used by the scientist Sir John F.W. Herschel in 1839. It’s a method of recording images by the action of light‚ or related radiation on a sensitive material. Alhazen (Ibn Al-Haytham)‚ a great authority on optics in the middle ages who lived around 1000 Ad‚ invented the first pinhole camera. The first casual reference to the optic laws of pinhole cameras was by

Reflex acts were one of the first human reactions to being studied. Descartes was the first beginning a study model of reflex acts‚ this to be able to demonstrate that the body worked like any other machine. Another scientist in studying this phenomenon‚ Robert Whytt. He was a Scottish physicist and physicist. He inclined his research around action-reflex‚ differentiating voluntary and involuntary movements. Describing the pupil reflex to light (reflecting Whytt)‚ he further proposed that the arches

most basic circuits is a reflex arc‚ which occurs rapidly in response to inputs from the sensory neurons and consist of only one or a few afferent and efferent cells. Such a response is very quick and automatic. Reflexes are among the oldest and most important features of nervous systems‚ because they allow animal to respond quickly to potentially dangerous events.

Instagram. But it hasn’t been forever that someone was able to capture their favorite moments in a photo. The early camera was not much more than a pinhole camera as early as 1558. It was called the Camera Obscura. The Camera Obscura was seen as a drawing tool for objects. An image of a subject on paper was "projected" and could be used to draw‚ trace or paint it. The Camera Obscura provided an image that was temporary‚ and could not be lastingly captured on to paper for later. Around 1822 French
