Using Aperture Priority

So is your camera still set on AUTO? YES, then it’s time to make that next move into the amazing world of photography by just simply turning the dial round to (A) Aperture Priority.

Ok, I’ve done that you might say now what does it do? Aperture Priority basically allows you to control the amount of light which gets through your camera’s lens and therefore captured by the image sensor within the body of the camera. The amount of light is controlled by a function known as F/stops, and the range of f/stops will all depend on the lens you have fitted, kit lens normally range from around f/4.5 – f/22 with the more expensive lens starting at least say f/1.2 So which number does what?

The thing to remember here is the lower the f/ Stop number the more light the camera will let in, the higher the f/Stop number the less light the camera lets in.

So you’re now possibly thinking to technical for me, I’m going to switch back to AUTO and not worry about them. Well please don’t switch back to Auto, Trust me as you start to learn more about using Aperture Priority you will soon see that these f/stops just simply control two things, like I’ve already said the amount of light, and the second thing they do is control the depth of field within the image (will discuss depth of field in a later hints and tips)

ISO100, 12mm, 1/10sec f/9

ISO100, 12mm, 1/10sec f/9

As you can see by the above image an f/stop of f/9 has allowed in more light than the same image taken below using an f/stop of f/13, The reason for this, is all due to the speed in which the shot was taken. As by using Aperture Priority you are allowing the camera to control the shutter speed, which is great as a beginner because you only have one camera function to think about at this stage.

ISO100, 12mm, 1/15sec, f/13


So hopefully this simple break down into the world of Aperture Priority, will make you think about turning that dial away from Auto and over to (A) give it go, and once you do you will never switch back to AUTO.
