I know some of you will think these are very basic and boring...but I promise you, you will learn something new!!! You can always learn new things! We will be doing all this on manual.
Photography is all about recording light. In order to record light, you need to know how to tell the camera how much light to record. Understanding photography exposure allows you to give correct instructions to your camera. After all, your camera is just a tool, you are the artist.
Exposure is made up of Light and Time.
Light- how much, controlled by aperture (f/stop)
Time- how long, controlled by the shutter speed (SS)
Apreture-(f/stop) it opens and closes, it controls how much light is allowed to come in and strike the film or digital sensor. It's an adjustable opening inside the camera lens that works very similar the iris in your eye.
When the aperture opens wide (like your eye dilating), more light is allowed through the lens to expose the film. When the aperture is narrow (like your pupil in bright light), less light reaches the film. Aperture works in conjunction with shutter speed and film speed to determine the total amount of light that reaches the film. Aperture size also affects depth of field.
Aperture is measured using F-Stops. F-Stop numbers represent a fractional formula representation of the amount of light allowed to pass through the aperture. In simpler terms, F-Stop numbers get bigger as the aperture gets smaller, just like shutter speed numbers get bigger as the time the shutter is open gets smaller. Each increasing F-Stop number roughly represents a halving of the light reaching the film.
Whole stops in aperture:
f/1.4
f/2.0
f.2.8 for the purpose of lessons we will do whole stops
f/4.0
f/5.6 the size of the aperture decreases as you go up.
f/8.0
f/11
f/16
f/22
http://en.wikipedia.org/wiki/F_stop, gives you a picture.
The larger the number, the smaller the aperture.
Lesson#1 OUTDOORS
I want you to use your light meter. Study light and shadows. Pick your subject and determine the light it is in. Set your Shutter speed and ISO to 200.
Here's how to read your light meter.
