There’s nothing worse than realizing that your images have dust spots after you’ve taken them. To avoid this issue, you can use this simple checking for dusty sensor steps to check for dust on your camera sensor and clean it before you take photos.

Technique for Spotting Dusty Sensor

One popular method involves taking a photo of a plain white paper and reviewing it for dust spots. However, this method may not show all the dust spots, particularly the tiny ones. Therefore, it’s best to use a more efficient technique to check for dust on your camera sensor.

First, set your camera to manual focus and focus the lens to infinity. You don’t need to focus on the paper. We want the sensor to capture a blurry image.

Next, set your camera to the lowest ISO setting or Auto ISO and select Manual Exposure mode. Set the shutter speed to around 1 second and the aperture accordingly to make a slightly overexposed image (about one stop). This will allow you to take a brighter photo to spot the dust easily. Then, point the camera at the white paper, and while moving the camera up and down, take the picture.

Moving the camera will create a blurry image of the paper, making any dust spots on the sensor more visible. If you can’t see any spots, zoom in on the image and scan for smaller ones. This technique will help you identify any dust spots on your camera sensor before you go out to take photos.

In upcoming articles, we’ll discuss how to automatically and manually clean the sensor and use Lightroom or Photoshop to remove dust from photos. If you have any questions, don’t hesitate to contact us.
