In 1839 Louis Jacques Daguerre (who worked with Joseph Niepce), announced a new photographic process called Daguerreotype to the [[France|French]] Academy. The process was more practical than ''Heliography'' and ushered in the photographic era.

'''Exposure''' is the amount of light needed to form an image. This is measured with a light meter that are built into modern cameras. It turns on immediately when the camera is switched on. The light meter sensitivity is adjusted by the ISO settings (ISO means: International Standards Organisation). ISO is also sometimes referred to as ISO Ratings.

===Light Metering===

====Light Metering====

There are two types of light meter readings. One is called ''incident''. This is where the light falling on the light meter (a hand held light meter) calculates the exposure. The second (which is on SLR cameras) is called ''reflective'' light metering. This is the light that is registered reflecting off the object being photographed and reflecting into the camera.

Multi zone metering is when the camera evaluates the whole image then decides the best exposure (this is the most commonly used setting, it is often used in landscape photography).

Centre-Weight average metering is when the camera calculates exposure based on the centre of the image (this is common in portrait photography). Spot metering is when a small select area in the image is used to calculate the overall exposure.

Flash photography is when the main exposure for the image you are taking is based on the flash it self. There can be just one flash or multiple. With multiple flash units one is referred as the main.
