basics of photography


Exposure – shutter speed, ISO , and aperture

Shutter speed = exposure time of the photography

ISO = the cameras sensitivity to light

Aperture = the size of the hole in the lens

using the light meter in your camera – 2 different lights                                     incident light = the light coming from the sun or a light source to the object being photographed                                                                                             reflected light = the light bouncing off the object

black ———-grey————-white


Hard light creates shadows, soft light doesn’t.                                                      can’t get blacker than black or whiter than white. This is because both black and white have nothing in them.

Use spot metering to accentuate highlights and shadows.

A reflected light reading tries to expose for a neutral grey in the scene.               A incident light reading simply measures the amount of light falling on the subject or the scene.

For a darker subject matter you need a higher ISO.                                                 For a lighter subject matter you need a lower ISO.

When in the studio you need a light meter because of the flash used – can’t register amount of light that will be there.

Aperture – smaller hole – bigger number                                                                             -bigger hole –  smaller number                                                                                     A smaller aperture gives a shallower depth of field.                                              If the camera lets in a lot of light it allows the object to be shot in dim light. If it is too bright you can change the shutter speed.

each time you go up or down with aperture it is halving or doubling the amount of light. Eg/ F11 is half the amount of light as F8. F8 if half the amount of light as F5.6.

shutter speed – the speed at which the shutter is opened. usually measures as fractions of a second. Eg/ 1/30 is a 30th of a second. 1/60 is a 60th of a second

You should never used a shutter speed which is smaller than the focal length of the camera, as this will then cause camera shake.

correct exposure – what aesthetic look/ approach you want
