Some people are technical learners, able to learn with a mathematical approach. Some others, including myself, don\u2019t take to that technical approach very well. When I make an exposure, I begin with the subjective idea or the impact I want to create, and then think about the technique that will produce that impact, a moment later. But I would never have been able to make decisions about how to create an impact if I didn\u2019t pay attention to the technical ways of making a shot.<\/p>\n\n\n\n

If we take a look at how an image is made in the camera, there are a few things we have to think about in the process of making that image. We have to think of the available light, the sensitivity of the camera sensor, the amount of light being let in, and the speed at which the camera is able to capture what\u2019s in front of the lens. To really get down to the basic technicality of making an image, you have to start with these four things.<\/p>\n\n\n\n

Why is shutter speed important anyway?<\/strong><\/p>\n\n\n\n

Available light is the quality and amount of light that is reflected off your subject. The sensitivity of the camera sensor is indicated by the term ISO. The higher the number of the ISO, the more sensitive the camera sensor becomes. That means a high ISO helps the camera see with less light available. The amount of light that you let in through the lens is controlled by the aperture, or the size of the lens opening at the moment of capturing the photo<\/a>. Finally, these three things combine to produce the shutter speed, or how fast the camera can capture the image with the amount of light it has available.<\/p>\n\n\n\n

There are some basic relationships we can glean from the above information.<\/p>\n\n\n\n
