How To Blur The Images Background In DSLR
Hello photographer! In this article, I will show you how to blur the background in DSLR photography. Blurring the background of an image is a great way to make it look more professional and less like your everyday snapshot. Blur also helps bring attention to your subject, which can help tell a story or express emotion.
Blurring backgrounds isn’t as hard as you might think either! This technique requires a DSLR camera, basic manuallyaperture settings (f-stops), and patience while experimenting with different backgrounds and angles.
Why Would You Want Blurry Backgrounds
Blurred backgrounds are eye-catching, look professional, and create an emotional connection with your audience. Professional photographers use this to place focus on their subjects while also reducing the distraction of other elements in the image. This technique can be used for practically all forms of photography but is most often seen in portrait work.
First, you need to choose your background. I like picking one that has some texture, so it looks more attractive when blurring. A smooth surface can look out of place when blurred, so picking a subject with texture is essential. Also, try not to choose too busy or distracting of a background.
The photo (and the viewer) should be drawn to your subject, not distracted by everything else in the image. I like using natural light when blurring backgrounds because it produces more appealing results than strobes or flashes.
To achieve maximum blur, you will need to use relatively low f-stops (higher aperture number, e.g., f/16 or f/22). Keep in mind that the lower your aperture number is, the harder it will be to focus – specifically if your subject is further away from you. If you find yourself struggling to keep a sharp focus on your subject while using low f-stops, try switching to a manual guide and focusing on an area of your subject that you want to be in focus on.
Depending on how fast or slow you wish your subject to move, you will also need to play around with different shutter speeds. For example, if I am photographing someone walking, I would select a lower shutter speed, so the whole person is in focus and properly exposed while the background is properly blurred. On the other hand, you can select a higher shutter speed to capture action shots without blurring your subjects.
Try experimenting with different f-stops and shutter speeds until you find what works best for your photo! Blur isn’t something that can be achieved overnight. It will take some practice and patience before achieving pleasing results.
What Affects Background Blur
Triggering Your Camera
There are two ways to trigger your camera: wireless and wired. I prefer using a wired remote as it begins the camera as soon as you press the button on the small compared to waiting for the signal to be transmitted from a wireless remote. A standard, unmodified DSLR will not fire unless it receives a ‘half press’ signal from your wired remote (some cameras can be programmed to fire without a half-press). If you do not have a wired remote, you can also use the timer mode to shoot instead.
A slow shutter speed yields blurred results, while a faster shutter speed will capture movement in images. The best type of blur is a complete, unfocused background with a sharp subject.
A shorter focal length can create more background blur because it has a wider angle of view. A 50mm lens will have less blur than an 18mm lens.
The lower your f-stop (e.g., f/2.8), the greater the blur you will achieve with the same shutter speed and focal length.
Distance From The Camera
The closer you are to your subject, the more blurred the background will be. If you want less blur, move further away from your subject. This also applies to adjusting the focal length of your lens (the wider it is, the less blur).
Lowering your ISO increases shutter speed and reduces image noise. This also decreases the chance of getting blurry images.
Not only will a lens with a larger aperture produce more background blur, but a higher quality lens can be sharper and have better color reproduction than lower quality lenses. Remember to use prime lenses rather than zoom lenses when photographing people because prime lenses are made for taking photos of people rather than landscapes. Zoom lenses are not great for taking pictures of people because they’re too “zoomed in” and lose the impact of your photo when photographing people.
How To Use Depth Of Field To Blur The Images Background in DSLR
Depth of field, also known as “DOF,” is the area of a photo that’s in focus. Depth of field can be used to your advantage when it comes to controlling what parts of an image are sharp and which parts are blurred.
When using depth of field for portraits, you want to have a narrow depth of field so that the subject is in focus and the background is out of focus. This draws attention to your subjects and blurs the busy or distracting backgrounds, which can be very useful if you take a photo of someone against an unappealing background.
When photographing landscapes, you want a wide depth of field so that everything from near to far is in focus. This should be done when taking pictures of landscapes because you want to capture everything you’re seeing.
To control the depth of field, you will need to adjust your f-stop (f/2.8 is wider while f/22 is narrower). You can also change your focal length (zoom in or zoom out) and distance from your subject (closer or further away).
Ways to Blur the Background Using Your Camera's Settings
1. Aperture Priority Mode
Aperture priority mode, also known as “Av,” is when you choose the aperture. Your camera automatically adjusts the shutter speed for you using either an in-camera light meter or by allowing you to manually input a shutter speed (depending on which camera model you’re shooting with).
2. Shutter Priority Mode
Shutter priority mode, also known as “Tv,” is when you choose the shutter speed and your camera automatically adjusts the aperture for you using either an in-camera light meter or by allowing you to manually input an f-stop number (depending on which camera model you’re shooting with). The shutter speeds for photographing moving subjects range from 1/500th of a second to 1/4000th of a second.
3. Manual Mode
Manual mode lets you control the aperture and shutter speed yourself (without relying on your camera’s built-in light meter). To properly expose an image, choose an f-stop number (f/2.8 is wider while f/22 is narrower). Then, use your camera’s light meter to help you figure out what shutter speed you should be using.
4. Program Mode
When in program mode, you can control either the aperture or shutter speed but not both. This mode allows your camera to do all of the thinking for you when it comes to exposure. You should usually use a shutter speed that’s either 1/60th of a second or 1/125th of a second in this mode.
5. Image Stabilization Mode
Turn on camera image stabilization when you’re dealing with low-light situations and your shutter speeds are starting to get too slow for hand-held photography (1/60th of a second or slower). Image stabilization modes will tell your camera to use slower shutter speeds, especially when you have the camera held out in front of you while taking a photo.
Now you know the tricks of blurting images background in DSLR, and hopefully, these tips will result in more successful photos for you! Good luck and happy shooting!
Q. I have a Nikon DSLR camera. How do I create that "classic blur" background effect?
A. It’s straightforward to apply the classic blur backgrounds effect on your photos when you own a Nikon DSLR camera. All you need to do is make sure that your lens has an f/2.8 or lower aperture setting, then just set the camera’s shutter speed to be 1/60 of a second or slower.
Q. What is aperture priority mode?
A. Aperture priority mode, also known as “Av,” is when you choose the aperture and your camera automatically adjusts the shutter speed for you using either an in-camera light meter or by allowing you to input a shutter speed manuallyto input a shutter speed manually(depending on which camera model you’re shooting with).
