word “photography” comes from the two Greek words photos, which
means light, and graphein, which means to draw. So if we put them
together, it will literally mean “to draw with light”. A
photograph is produced by some sort of chemical reaction between
certain chemicals and light. The result would be a picture that is
drawn on to a flat surface which is a photo or picture. So if we look
at the literal meaning, we can say that taking a picture is actually
drawing something on a flat surface with light.
