My name is Reg Wilkins and today we'll be talking about the camera obscura and how it works. The camera obscura, or a dark chamber as some call it, is an optical device used for example, in drawing or for entertainment, each one of thee devices and thee evolution of photography as we know it today. The principle can be demonstrated with a box with a hole in one side. The box can vary in size. Light from a seem passes through the hole and strikes the surface where it is reproduced. The images perspective will be accurate. The image can be projected onto paper, which when traced, can produce highly accurate representation. As an opening is made smaller, the image gets sharper, but the projected image becomes dimmer.
