Aperture
What is aperture priority?
Ok the most common mode you will probably end up using is Aperture Priority. Basically you are setting how big the centre of the lens opens up to let light in. Now what your camera does is keeps the shutter open for as long as it needs to in order to get your photo to the set exposure. Clearly if there is a very small aperture, then less light will make it to the sensor and you will need a long shutter speed.
Sometimes you will want this if you are taking photos of waterfalls or lakes, or city scapes etc as it can produce some interesting and amazing effects. By making your aperture as large as possible, you are letting in as much light as possible and therefore you will tend to have a quicker shutter speed, which is what you want for hand held photo taking such as this zoomed in shot of a butterfly below using a 300mm zoom lens on a Nikon D90.
