In photography the shutter speed and F-numbers are important factors for consideration. The right combination for both parameters is required for correctly exposed final photographic results. Therefore this area is essential knowledge for persons into photography. This article is about different built-in modes of exposures that are available for the camera user.

1. Manual exposure mode: This mode gives full control of the parameter setting to the user.

2. Aperture Priority exposure Mode. This mode is also known as AP: It allows the camera owner to set the desired aperture setting. The camera will in turn automatically determine the most suitable shutter speed. If you want good level of sharpness and Depth of field of the picture, this mode is suitable.

3. Program exposure mode: This is the preferred mode for persons new to photography. When this mode is selected, the camera will employ its internal in-built algorithm to determine the most suitable set of parameters.

4. DEP mode: Of the modes, this is one of the less common. This function allows the photographer to decide on the desired Depth of field. It give controls over which certain area to remain sharp and in focus.

5. Shutter Priority exposure Mode: This setting is ideal for controlling the exposure when a slow shutter speed is being used. In another word, it allows the photographer to set the required Shutter speed and the camera will automatically determine the best aperture setting or size for the setting. Shutter Priority Mode has the property of producing the highest Depth of field with regards to the given shutter speed.

In a nutshell, these are the various exposure modes.
