One of the oldest forms of cameras still on the market today is the camera lucida. This light, portable device has been around for about 200 years, but it isn't actually a camera. It is an optical device that artists use to help them draw. A camera lucida superimposes the object being viewed and the drawing surface. This enables you to see the object and drawing surface at the same time like a double exposure in photography. It also allows you to keep things in perspective and to trace the outlines of objects in the image.
If you use white paper the image is usually washed out and hard to see. If you use black paper and a white pencil you will be able to see better. This device isn't well known or popular, but is still available via art-supply channels. Years ago it was commonly used by microscopists. You don't need any special lighting conditions to use one as it doesn't actually project an image. You basically just look down at the drawing surface through a tilted mirror. This will superimpose a view of the surface and a reflected view of the image you are sketching. The device usually has a weak negative lens which produces a virtual image of the scene at approximately the same distance as the surface. This allows you to see them both together.
Camera lucidas come in various sizes, styles, materials and shapes. You may be able to buy a new model for about $375.
