Creating the perfect exposure and using shutter speed creatively

The aim this week is to work on maintaining perfect exposure. To tell if your image will be properly exposed you will need to use your exposure meter and adjust your aperture and shutter speed together to get that ‘little line’ to sit perfectly in the middle

Inside your viewfinder you should see something like this:

Last week you focused on what aperture your camera is set to:

These other circled numbers indicate what shutter speed you have your camera set to:

To find the perfect exposure you need to adjust your shutter speed and aperture together:

As you adjust make sure you pay attention to how low your shutter speed is going and avoid going below 1/60th of a second to hand hold an image you want to be sharp. Make sure you are thinking about what your depth of field will be as you adjust your aperture. Be wise about your image. Take your time to get the correct exposure for your situation before you start shooting! Use your LCD screen to see how well you are exposing your image. Adjust your settings if you are not happy.

How can shutter speed effect your image?

Shutter speed is the speed at which your shutter opens and closes and captures light. A fast shutter speed opens and closes your shutter very quickly, capturing the light and your image immediately. A slow shutter speed opens and closes more slowly and allows more time for the light to enter your camera.

Fast Shutterspeed / Slow Shutterspeed

A fast shutter speed will capture movement very sharply as it only gives the shutter a short period of time to read the image. The faster your image is moving the faster you need to set your shutter speed to capture it sharply. Using a fast shutter speed is also a great way to balance out your exposure on a bright sunny day when you want a shallow depth of field. (ie. you have your aperture wide open).

A slow shutter speed, together with a tripod or a propping your camera somewhere steady, will capture movement with a blurring effect. This is because the image will often move more quickly than the shutter opening and closing.

This can be helpful to give a sense of speed or a sense of movement. This can be helpful in low light situations as it allows the maximum amount of light to get into your camera. Giving you the best opportunity for a perfect exposure. It also helps isolate a moving image when used in conjunction with panning.

You should use Aperture and Shutter speed together to give you a correct exposure as well as the appropriate effect you want for your image.

This week in your photos you bring to class I’d like to firstly see you using shutter speed and aperture together to get a perfect exposure. It would also be great to see you use shutter speed to give you creative control. One purposeful fast shutter speed photo and one slow. If you choose to use a shutter speed below 60 blurring the subject to create a sense of movement make sure you use a stablizer or tripod of some sort. Be wise about what you shoot, does the shutterspeed you’ve chosen enhance the photo or detract from it. If you want take a photo that ‘shows’ movement but dont have a tripod, how about experimenting with panning, you can use a low but not overly slow shutterspeed 30/60 as long as your subject is moving quickly enough.
