Pinhole Photography. A camera has a few simple components: A light tight box Aperture – A hole through which light enters the camera. Shutter – A way.

Pinhole Photography. Photography is the process of making pictures by means of the action of light. Light patterns reflected or emitted from objects are.

Pinhole Photography To do pinhole, all you really need is a light-tight box. Almost anything can be turned into a camera. All kinds of light-sensitive.

Interacting with light

Exposure Defined In photography, exposure is the amount of light per unit area (the image plane illuminance times the exposure time) reaching a photographic.

The basic principle behind the rule of thirds is to imagine breaking an image down into thirds (both horizontally and vertically) so that you have a grid.

Learning Objectives Construct a pinhole camera View the image of a candle using a pinhole camera Investigate the effect of the aperture (size of the hole) Investigate the use of a lens Investigate the effect of multiple pinholes

Task Draw the image with one small hole. Draw the image with a larger hole. What happened when you placed a lens in front of the hole? Describe the effect of making multiple holes. Task

Task The image is clear but not very bright! Draw the image with one small hole. Draw the image with a larger hole. What happened when you placed a lens in front of the hole? Describe the effect of making multiple holes. Task The image is clear but not very bright!

Task The image is brighter but blurred! Draw the image with one small hole. Draw the image with a larger hole. What happened when you placed a lens in front of the hole? Describe the effect of making multiple holes. Task The image is brighter but blurred!

Task The image is brighter and sharp. Also it is the right way up!! Draw the image with one small hole. Draw the image with a larger hole. What happened when you placed a lens in front of the hole? Describe the effect of making multiple holes. Task The image is brighter and sharp. Also it is the right way up!!

Task Multiple holes means multiple images!!! Draw the image with one small hole. Draw the image with a larger hole. What happened when you placed a lens in front of the hole? Describe the effect of making multiple holes. Task Multiple holes means multiple images!!!
