Photography: Exposure Modes
In the world of photography, exposure refers to the amount of light that touches the sensor of the camera. By adjusting the shutter speed, a photographer can achieve the maximum exposure needed to ensure that the subject or scene will be captured as exactly as possible. Having a wide aperture also helps in increasing camera exposure.
Different photographers have different tastes when it comes to dealing with their camera exposure. While some prefer to adjust it manually, others would want the exposure setting to be fully automatic. Still, there are people who would want a semi-automatic exposure setting. For scene modes, they have factory-enhanced settings that can be appropriate for different types of subjects.
Here, your camera does all the work, depending on the level of illumination upon or around the subject or scenery. In the fully automatic exposure mode, all you need to do is to press the shutter release button halfway. While you are doing this, your camera focuses automatically to the subject and scene you want to capture. If there is little light around your subject or it is too dark, the flash will also work automatically.
There are digital cameras equipped with the Program AE mode (P mode). It is the mode responsible for setting the aperture and shutter speeds automatically. Of course, you still have the discretion to use any kind of ISO number for your photo scenes. The same thing applies for adjusting the white balance setting of your camera.
Aperture priority mode (AV) – Select the aperture (lens opening) and then the shutter speeds will set itself automatically.
Shutter priority mode (TV) – Select the shutter speed and then the aperture will set itself automatically.
In manual mode, it is up to you to select the different settings of your camera. If you want to adjust the white balance setting of your camera while maintaining a high ISO mode, then you are free to do so. If you want to maintain a particular shutter speed or aperture for a particular scene, then go ahead. But if you need assistance, your digital camera has a tool for providing you all the options you need. This will ensure that you get the proper exposure for a particular scene.
