Some of the background problems that photographers are most likely to encounter are the subject of noise that is disturbed when taking pictures. This is a very common problem, especially scenes taken in real life. Sometimes when you click, there is a head or someone’s face poking in. The result is that the image of the person or thing you’re about to focus on is distracted by these uninvited ingredients. In addition, when taking photos, the photographer does not notice scenes or other objects in the background. Therefore, when I look back, I saw that a person had a tree or a pole growing, or a roof or a wire hung across the middle of the head. In addition, the subject’s focus is on lines, but there are even darker lines and lines in the background, opposing the idea of the main subject’s lines and lines. Here are 9 tips to help overcome background noise errors when taking photos
1. Check the background before shooting.
It sounds nothing special, but this seemingly simple problem everyone has. Therefore, it is best before you prepare to take a photo, take some time to look at the background of the background to see if there are any problems with colors, lines or objects that can distract attention. into the main subject or not.
Actually this is just a very simple trick, but not everyone remembers. If you are taking portraits, ask the model to move slightly to the left or right. Sometimes by translating a little, you can push unnecessary objects or objects out of your background.
3. Change the shooting angle.
If many objects cause interference in the background but cannot move the subject, consider moving yourself to another angle. You can either move left or right by yourself, or up to take the sky as a background or from above to take the ground as a background. All of these can help eliminate jamming objects from the frame.
4. Use the lens to blur the background.
One of the most effective methods of removing noise from the background is to use the lens itself to blur the entire background. Keeping the aperture large (the smaller the f-number) down to f / 4 or f / 2.8, you will make the subject stand out more on a completely defocused background.
5. Use focal length to blur the background.
Another way to do this is to use a long focal length lens (telephoto lens). Long focal lengths tend to shorten the depth of field. Although the effect of the telephoto lens is sometimes not large enough to be realized and there is a lot of controversy surrounding this effect, the fact is that, due to the longer focal length, the subject will be “full” in the frame. than. Therefore, when combined with a large aperture, the background is more blurred and the subject stands out.
6. Place people or things to capture in front of an open space background.
Placing the subject in front of an open space background with objects in the distant background will further render them blurry. Imagine, photographing the subject against a background of a brick wall compared to the background of a distant field, you will immediately see the background blur effect on which background is more effective.
7. Let the object “fill” the frame.
One of the equally effective ways to eliminate background noise is to frame the object to shrink (by zooming or by moving) so that the main subject will cover most of the frame. This method can both eliminate effective noise, and can create some other impressive impressive effects.
8. Create your own background.
Sometimes you will find yourself in a situation where you cannot find a background that suits your own intentions. At that time, think about preparing your own background. The background may be a single-color fabric or compact colored cardboard, you can bring a backpack and mount it on the wall to change the color when needed.
If shooting in a studio is simpler, because you can buy as many background backgrounds as you want. If you have to shoot indoors, pay attention and may need to clear all the furniture at a certain angle to reduce the need to shoot so that the furniture will not disturb the subject.
With the advancement of technology and software, post-image processing is also one of the effective techniques to eliminate background noise. Depending on the level and software you use, there are various techniques to remove the background, change the background, remove the noise object or change the total background to black and white while keeping the main object as color. The creativity now depends entirely on your skill level.
