A camera obscura (Latin for "dark room") is an optical device that led to photography and the photographic camera. The device consists of a box or room with a hole in one side. Light from an external scene passes through the hole and strikes a surface inside, where it is reproduced, inverted (thus upside-down), but with color and perspective preserved. The image can be projected onto paper, and can then be traced to produce a highly accurate representation. The largest camera obscura in the world is on Constitution Hill in Aberystwyth, Wales.
Using mirrors, as in an 18th-century overhead version, it is possible to project a right-side-up image. Another more portable type is a box with an angled mirror projecting onto tracing paper placed on the glass top, the image being upright as viewed from the back.
As the pinhole is made smaller, the image gets sharper, but the projected image becomes dimmer. With too small a pinhole, however, the sharpness worsens, due to diffraction. In practice, most camerae obscurae use a lens rather than a pinhole (as in a pinhole camera) because it allows a larger aperture, giving a usable brightness while maintaining focus.
A camera is an optical instrument for recording images, which may be stored locally, transmitted to another location, or both. The images may be individual still photographs or sequences of images constituting videos or movies. The word camera comes from camera obscura, which means "dark chamber" and is the Latin name of the original device for projecting an image of external reality onto a flat surface. The modern photographic camera evolved from the camera obscura. The functioning of the camera is very similar to the functioning of the human eye.
A camera may work with the light of the visible spectrum or with other portions of the electromagnetic spectrum. A still camera is an optical device which creates a single image of an object or scene, and records it on an electronic sensor or photographic film. All cameras use the same basic design: light enters an enclosed box through a converging lens and an image is recorded on a light-sensitive medium. A shutter mechanism controls the length of time that light can enter the camera. Most photographic cameras have functions that allow a person to view the scene to be recorded, allow for a desired part of the scene to be in focus, and to control the exposure so that it is not too bright or too dim. A display, often a liquid crystal display (LCD), permits the user to view scene to be recorded and settings such as ISO speed, exposure, and shutter speed.

Look for a blank wall opposite the window, since that's where the picture will be projected. If it's not blank, hang a white sheet on the wall. Step 2: Create the lens Unscrew the ring from the top of the flashlight and remove the lens. Place the ring in the middle of the sheet of poster board, and cut a hole around it.

This is a tutorial on how to make a peculiar little device called a Camera Obscura. That means “Dark Chamber” in latin. It is box with a lens that projects an image of the world. And it is something that goes all the way back to antiquity. Even Leonardo DaVinci and Johannes Kepler wrote about it. Some were even as large as a whole room or building that projected the image onto a wall. This was a very early precursor to the modern day camera. And you can see why. All you have to do is replace our wax paper with photographic film and you have a rudimentary camera. Our Camera Obscura is a hand held box that projects the image onto a piece of tracing paper or wax paper and you just need a lens and a small mirror to make it. You can even use this one to make drawings of scenes. I have a web...
