Photography Education and Training Key Terms

Understanding basic concepts in photography will enable interested students to select appropriate courses

People training to be photographers need to be familiar with the vocabulary used in the field of photography. Camera types, settings, exposures, and touch-up processes are all important areas the photography student needs to learn. When choosing a school, an online course, or even a stand-alone class to increase your photography skills, look for one that covers information about these topics. Developing your competence or understanding in any of these key areas is bound to make you a better photographer.

Aperture priority (Av)

Aperture priority, or Aperture value (Av), is often marked "A" on a camera. This setting lets the photographer select the size of the camera opening. The camera then chooses the shutter speed that will give the best exposure.

Flash photography

Flash photography uses a flashgun to achieve certain effects in the pictures a photographer takes. By using a flash, a photographer can enhance or override the available light to ensure better results.

Digital single-lens reflex (dSLR) camera

A dSLR, or digital single lens reflex camera, sends light to the viewfinder via a moving mirror system behind the lens. The mirror moves when the shutter clicks so light reaches the sensor. A prism lets the photographer view exactly what will be seen on the film. Because these cameras are becoming more popular, photographers should be knowledgeable about their capabilities.

Exposure and metering

Different metering modes determine the amount of light and the length of time the shutter remains open. The exposure compensation (EC) feature can correct under- or over-exposure. Learning the correct exposure for the situation and the proper metering mode to use are both valuable skills for any photographer to learn.

Photo-editing software

Many pictures can benefit from photo-editing software. These programs enable photographers to adjust lighting, remove dust, even out skin tones, cover blemishes, delete unwanted items, and otherwise enhance their photos. Most education programs for photographers include training of this kind.

CCDs and CMOSs

CCDs are Charge-Coupled Device image sensors. They are different from CMOSs, which are Complementary Metal Oxide Semiconductors. Both of these image sensors convert light into electrons. CCDs provide high-quality images with many pixels and good light sensitivity. CMOS sensors usually give lower quality and lower resolution images.
