Many people ask me if there is a secret to getting sharp photos. I often respond that it is a combination of a few factors. These factors include shutter speed, aperture and f-stop, using a tripod and distance to subject. These things work together to create a sharp image. Once you learn how to work these things together you can say goodbye to blurry images.
Blurry images can be caused by camera shake. Camera shake is the movement of the camera when you take the photo. You may have noticed that when you are shooting in low light, there is a little bit of blur throughout your image. This is due to the shutter speed slowing down and accidentally recording the movement of camera when you press the shutter button down.
There’s an easy way to fix this. Blurry images due to camera shake are preventable. What you need is a tripod. In low light situations the shutter will slow down. It slows down so that you can capture as much light as possible. If you move the camera when the shutter is open your image will usually be blurry. If you hold the camera very still you will see that this problem may go away entirely. A great way to keep the camera still is to use a tripod. A tripod will prevent blurriness duty camera shake.
Shutter speed and sharp photos go hand-in-hand. The quicker your shutter speed is the less likely you are to accidentally blur your image. If you do not have a tripod then simply photograph your subject at a faster shutter speed. This requires using the camera in manual mode. Using the camera in manual is by far the best option because it gives you the most control. Remember, the camera doesn’t take photos, you do.
Sharpness in photos is also attained by using the correct f-stop. Your f-stop is a numerical representation of your camera’s aperture. Your lens determines what f-stop range your camera has. The higher the number f-stop means the sharper your photo will be. This is because it controls your depth of field. Depth of field means that area of your photo that is in focus. If you try and take a photo with something in the distance and you use a low f-stop number such as F2 .8, you will find that not everything in the scene is sharp. The best way to get good sharpness in your photos is to use the right aperture for the scene. The more that your subject is in the distance the higher the number you will need. The close your subject is the small the number you may use.
If you have a DSLR camera you will have the ability to interchange lenses. Interchanging lenses is a wonderful way to have more control over getting sharp photos. You will see that on the side of your lens there is a small switch or slider controls automatic or manual focus. If you find that the camera is unable to focus on your subject, due to low light or distance, you can always switch your focus to manual focus.
Let’s take the example of photographing a subject at night time. Sometimes the camera will struggle to see the subject when you use auto focus. If there is not much light the camera won’t be able to see what it is supposed to focus on. If you are able to see the subject well you can simply switch your focus to manual. Turn the focus ring on your lens to bring the subject into clear focus. You may find that you get a sharp image this way.
These are just some of the things that you can do to get sharp photos. You will find that the more practice you do the better your photos will look.
