The SLR Camera
Camera - SLR (Single Lens Reflection) What you see is what you get. - Images enters lens and is reflected to the view finder
Parts - Body - Lens - Flash - Tripod/ Monopod
There are two factors that you will be concerned with:
Focus : To ensure picture is sharp Light metering : To ensure that picture is not too dark/bright.
Focus
There is a switch to change to manual focusing. Its more difficult as the eye is not very accurate. (Cockeye) Sometimes it comes in handy - Fast - At your own control
Easy focusing. Just hold’ shuttle release’ halfway down Usually focus at the centre of the picture More Accurate (Camera not so cockeye; unless otherwise using lousy camera) Slow Noisy
Light Metering
Ability to measure amount of light Indicates if picture is under/over expose to light Parameters to be adjusted to ensure enough light enters the camera
Parameters
Aperture The size of the slit (hole) that the light comes through the film f/x where · If x is small means larger aperture · If x is big means smaller aperture
Large Aperture Smaller number e.g. 4.5, 5.6 More light goes through the camera For night shoot/dim lighting, taking pictures of close up face
Small Aperture Larger number e.g. 32, 22 Less light get through For bright/strong sunlight, landscape
Shutter Speed The speed that the shutter opens and closes The duration of time the shutter is left open
Measures as 1/x seconds
Fast speed for fast moving objects e.g. boy running 500m, speeding cars 2000 * Note less light gets to the film
Slow speeds for very dark situations, objects must be extremely still. E.g. Buildings *Note more light gets to the film
Any speed below 45 is slow; use a tripod to prevent camera shake With Thanks to Mr. Roshan for the above notes.
