How to Blur Background in DSLR Nikon D5300

If you want to take your photography skills to a new level, you can try blurring your background. This technique emphasizes the most interesting elements of your shot, and it’s easy to do on a Nikon D5300 DSLR camera.

To start, you’ll need a Nikon D5300 DSLR and a lens with an aperture range of f/2.8 to f/22 (i.e., it has a wide opening that allows more light in). A 24mm is ideal. On the upper right side of the body is the power switch and shutter-release button, which looks like a small metal circle with an arrow pointing up into it.

The dial lets you select shooting modes including “auto” and “scene” as well as exposure compensation values between minus five stops plus five stops (which should be enough for most situations). You can also use manual focus when taking shots at close distances or with subjects that move quickly because auto-focus isn’t always reliable for these types of shots.

Change to aperture priority mode

Change the AF/MF switch on the lens. You can’t change your camera’s aperture setting unless the camera is in manual focus mode.

Point the camera at your subject. To achieve maximum blurriness of your background, you should make sure that any foreground objects are not closer than 3-4 meters (10-15 feet) to you because they might interfere with the depth of field and blur even more than you want them to.

Also, it is important that you do not point the camera at more distant areas of interest when setting up your composition because they will be even more blurred than objects closer to you and it will ruin your image composition altogether.

Choose an appropriately large aperture

Choosing the right lens and setting an appropriate aperture.

  • The first thing you want to do is choose a lens with a large maximum aperture. What’s the point of setting your aperture to its minimum if it’s only f/22? Most modern-day lenses have a maximum aperture of f/2.8 or larger. If yours doesn’t, consider renting one instead. When shopping for used lenses at camera stores or online, pay attention to their listed maximum aperture values.
  • Switch to Aperture Priority mode on your camera and set the lowest available number (the largest aperture). This will ensure that you are using the widest possible aperture when taking pictures.

  • Set your ISO as low as possible without increasing the shutter speed beyond 1/200th of a second for handheld shots or 1/30th for tripod-mounted shots (or even lower if you’re using an extremely long telephoto lens).

Change the AF/MF switch on the lens

The AF/MF switch controls if the lens is in auto-focus mode or in manual focus. The A setting means that the camera will decide what to focus on. The M setting means you will decide what to focus your shot on. Most lenses have an AF/MF switch that allows you to choose which mode you want to shoot in.

Point the camera at your subject

Look through the viewfinder and point the camera at your subject. Your camera will focus on whatever is in the center of your frame. If you have the AF option engaged, you’ll notice that the autofocus (AF) image in the viewfinder lights up to confirm that it has found something for you to focus on.

Press the shutter button halfway

  • Press the shutter button halfway.

When you press the shutter button halfway, your camera focuses on whatever it’s pointed at and also varies other settings like exposure, flash, and white balance. The camera will take a picture when you press the shutter button completely.


There are four main factors that affect your ability to get a nice, blurry background. The larger the aperture, the blurrier the background, but there’s a trade-off: very large apertures will result in less of the image is in focus (“shallow depth of field”).

You can also reduce the depth of field by placing your subject further away from you or by getting as close as possible to your subject and zooming in. Finally, if you increase your ISO too much, then you’re going to start seeing digital noise when you take photos in low light. That same noise is going to be more noticeable when you zoom into 100% of an image.
