What is Exposure?

In digital

 photography, 

exposure is the unit of measurement for the total amount of light permitted to reach the electronic sensor during the process of taking a photograph. The two main controls your digital camera uses to control exposure are the shutter speed and aperture. However, ISO is also used. Slide3

Perfect Exposure

Perfect exposure is achieved when the lighting of a photograph is not too bright or too dark, but just right.Slide4

Histograms

Before you take a photograph on your camera, you can view a histogram which will illustrate how much light is in the photo. When your photo has perfect lighting, or exposure, the histogram will indicate this.Slide5

Taking Advantage of Exposure

While, for many photos, reaching perfect exposure is the goal, under and overexposure can be used to create dramatic photographic affects.Slide6

Remember…

Remember that there are two main controls which control exposure: shutter speed and aperture.

Shutter speed

is the time for which a shutter is open at a given setting. Aperture is the unit of measurement which defines the size of the opening in the lens that lets light through.

ISO

is how sensitive the camera is to light. Use a

high ISO

in low light, and a

low ISO

in bright light. Slide7

To Achieve Over Exposure

If

over exposure

is an exposure where too much light is let into the photo, then how can we allow this light in on purpose to achieve a dramatic affect?This can be achieved by a longer shutter speed and larger aperture.

By using these settings, more light is allowed into the frame of the photograph. Slide8

High-Key Photos

High-key lighting

aims to reduce the light

ratio, or contrast,

in a photo.

To achieve a high-key photo, you must use over exposure and some type of light in the background of your photo.Slide9

To Achieve Under Exposure

Under exposure

can be achieved oppositely of how overexposure is achieved.

If under exposure is where not enough light is allowed into the frame, then using a short shutter speed and small aperture will prevent this light from coming in.Slide10

Low-Key Photos

A

low-key photo

is a photo where everything (or almost everything) in the photo is black besides the subject.An “easy” way to achieve a low key photo is to take a photo with a very

short exposure

, and use flash or shine light only onto your subject. Slide11

In Conclusion…

Learning how to use your camera settings to achieve perfect exposure can be tricky, but learning this is the first step to using these settings to purposely achieve under and over exposure.

Once you learn how to use

ISO, shutter speed and aperture, you’ll be on your way creating your own photos with beautiful dramatic effects!
