As a South Wales Wedding Photographer, it is vital that I know my way around the camera on your wedding day. A camera consists of a light-tight box that stores a light-sensitive device (either a film or a digital sensor), a lens that magnifies and focuses the image onto that light-sensitive device through a hole in the box (called the aperture), and a shutter that opens and closes when you press the shutter release, exposing the film or sensor to the light; this is why a picture is called an exposure.
The amount of light entering the camera depends on the amount of light in the scenes/subjects that you’re photographing. A bright sunny cloudless day has more available light than a cloudy one, which in turn has more light than an indoor scene. To make the picture look right, we have to expose the film or sensor to the right amount of light.
Things to remember:
The longer you leave the shutter open for, the more light lands on the film/sensor, resulting in a brighter image. The bigger the number (i.e. 1000th sec) the quicker the shutter. This freezes motion. The smaller the number (i.e. 8th sec) the slower the shutter. This shows motion as blur. To eliminate camera shake, shoot above 60th sec.
The aperture is the hole through which light passes to reach the sensor or film. You control the diameter of this hole on your camera. On manual cameras, there is an aperture ring that goes around the outside of the lens. Moving it around changes the diameter of the aperture.
Aperture numbers are called f-stops. The smaller the number, the larger the aperture.
f2.8 – f4 – f5.6 – f8 – f11 – f16 – f22
Remember – assess the scene before you. Make a decision about the scene/subject before you. Is the shot dictated by aperture (and the effect of depth of field) or shutter (and the effect of blurring or freezing the image)? If using manual mode, then make an adjustment to whichever setting is dominant. Keep an eye on your light meter, and adjust the other setting so your exposure is correct.
Don’t forget to focus the shot. Half pressing your shutter button will set the exposure and focus the image. This is vital.
