Each of these key elements (ISO, shutter speed, aperture) controls the overall brightness of the exposure but has a different effect on the visual character of your image. Whether you shoot in Full Auto or Full Manual, someone (either the camera or you) has to make some decisions about what ISO, shutter speed and aperture to use. But how do you know whether you want low ISO and long shutter speeds or wide apertures and a faster shutter? We’ll map out the key factors that will guide your decision making process so that you always know what to do.
The first step in the process is understanding exactly how ISO, aperture, and shutter speed actually control the amount of light in your exposures. What are these three things actually doing to make the image brighter or darker? How do you know what ISO to use?What is under-exposure and over-exposure? What are whole stops and partial stops? How much light do you really need to let into the camera to take a picture in any situation?
Before you can make any decisions about how much light to let into the camera, you need to know exactly how much light you actually have available to you. For this you need to understand metering, which is simply measuring the light. Most cameras have light meters built-in, but there are several ways to measure the light and different methods work better for different situations. Learn all about the differences between reflective metering and incident metering, using external hand-held meters, and the various spot, average, and matrix metering modes in your camera.
Understanding Shutter Speed
Shutter speed affects the brightness of your exposures but it also affects the visual style of your image by altering the way that time is recorded. This session is all about learning how shutter speed can be used creatively to freeze a moment in time or to convey a sense of energy and movement in an image.
Understanding Depth of Field
Besides controlling brightness, aperture has an affect on the amount of background and foreground blur in your images. This background blur effect is called Depth of Field and it’s one of the most creative tools available in photography. But, aperture is only one of several key factors that control depth of field. This session is about truly understanding how depth of field works and how things like aperture, focal length, focus distance, and the size of your sensor affect the amount of background / foreground blur you can get in your images.
