If you are new to operating a camera, here are 10 things you must know about it.
1. Shutter speed: The shutter speed tells you about how fast your shutter is opening and closing. The longer it’s open, the lighter you’re letting in. If you have a slower shutter, you can capture motion blur; with a faster shutter, you’ll stop the motion.
2. Aperture: Aperture, or f-stop, refers to how wide the opening of your lens is. The wider it’s open, the more light it will take in. With a wide aperture, your lens blurs the background; with a small aperture, your background is more in focus.
3. Iso: ISO refers to how sensitive your sensor is to the light that’s coming in. The higher your ISO, the brighter your image. With higher ISO, you’ll see more noise or grains in an image than you do with lower ISOs. So you’ve got to decide which settings you’ll be using to make your picture brighter or darker. When you let in more light with one, you have to let in less light with the other to get the same exposure.
4. Exposure: You’ve probably heard the term exposure when people talk about photography, but what does it mean? Well, it’s referring to how well lit your picture is. So when we talk about getting a “good” exposure, it really depends on which elements of your picture you want well lit. If you’re going for a silhouette, you’re looking for a good exposure of the sky, but your subjects are actually underexposed. If you want your subjects’ faces brightly lit against a bright sky, you’ll have to overexpose the sky so you can get a good exposure on the subjects. You need to decide which part of your picture to expose before you can figure out which aperture, shutter, and ISO to use.
5. Automatic mode: With your camera on Auto, you won’t be able to choose any of the exposure settings because your camera will do it all for you. It does this by taking in light across the entire picture and guessing a proper exposure. This is most likely the mode people will choose when they have no idea how to operate the camera, because it takes no effort or knowledge at all. But there’s no way for your camera to realize that a bright sky is throwing off the light meter, or that you are trying to capture a silhouette, so automatic rarely gives you the best picture. For the most control over your light settings, it’s best to use Manual mode.
