Many of us know what the noise can do to our pictures, but what is noise in photography? Noise is bad enough when it comes to photographs, but when you’re talking about digital photos this is even more important. When a picture is taken with an electronic camera, there are hundreds, sometimes thousands of different noises that could affect the quality of the photo. This is why it is important that you learn how to eliminate noise so that your photos have the clarity and color that they can offer. Learn what these noises are so you know what to avoid so that you take better photos in every situation.
Noise is unavoidable when taking digital photos. Even when the setting on the camera is manual and the camera is working properly, a flash is going to result in some noise. This noise is common and is something that just about every photographer will deal with at one time or another.
Digital noise reduction starts with eliminating the light that causes the most problems in a photo. This is typically the sunlight. In order to eliminate the sunlight you can use a simple filter that allows you to darken the background or focus on a bright object so that the background is the same as the subject being photographed. This is common with landscape shots and people like this look really good. If you are using a ring flash, use the slowest speed so that the background doesn’t catch the ring and cause a lot of digital noise.
Another source of digital noise is lighting. Be sure that the location you are shooting at has clean lighting and use an inexpensive tripod if possible. Lighting in itself is not a problem but when you are trying to capture movement it can be a problem. The flash from your camera may also be affecting the photos so try to aim the flash for the furthest away lights so that the noise isn’t as noticeable.
Other than eliminating the sources of the noise you will want to make sure that your image is as clear as possible. Digital photography is great and gives you the chance to capture beautiful shots, but you have to be able to control the noise to make those beautiful shots come out clearly. Keep in mind that you don’t want to be overly controlled as it can cause your photo to come out flat. Just remember that you aren’t trying to make a print; you are just trying to take clear pictures and keep the noise to a minimum. You will find that there are some techniques that help minimize the noise. There are also software programs available that will help you do it.
It all boils down to the human element. If you can control your exposure, focus and use your zoom then you will have no trouble eliminating digital photography noise. Remember that you are in control. You can choose a shutter speed that doesn’t affect the resolution or even leave the shutter open so that more light is able to go through to the photo. You have the right to choose whatever settings work best for you and the end result is a clear and crisp photo.
