Why Do Photos Get Grainy?

Before you learn how to repair grainy photos, it is important to find the exact reason why your digital photos may appear grainy. Some main reasons that may generate grainy images are:

  • Inadequate ISO Setting: One of the main reasons for grainy pictures is the high ISO setting on your device. ISO indicates the sensitivity of the camera’s image sensor to light. This as result, increases the visibility of noise or grain in the image.
  • Image Compression: When you save an image in any file format, it utilizes compression to reduce file size. This compression somehow discards some image data and leads to the loss of image artifacts, including graininess. Higher levels of compression can produce high graininess in the image.
  • Image Editing: Some image editing techniques, like an increase in exposure, shadows, or contrast, can generate noise in your photos. Aggressive editing or applying excessive sharpening can also contribute to the graininess of your image.
  • High Zoom levels or Digital Zoom:  Using high zoom levels can cause noise in your images. This crops your image and enlarges a position, which can increase the graininess in your digital photos.

How do I Fix Grainy JPEG Images?

Now that you are familiar with the reasons for your grainy photos, it’s time to avoid such issues and acquire clear and sharp images. There are several methods that you can apply to minimize graininess in your pictures. Some of them are:

Method 01: Use Low ISO 

Using higher ISO settings in a digital camera can manipulate the amount of light entering the lens and thus distorts the image. To avoid such a situation, you need to keep the ISO of your image as close to 100, if possible. However, when you need a higher ISO, try changing the aperture first and this changes the shutter speed (maximum 1/60 without a tripod/wall), as this will help in lowering ISO.

Method 02: Fix Grainy JPEG Images Using Photoshop

Many users found that using Photoshop is one of the simplest methods to fix graininess in their photographs. You need to follow the below-given steps to know how to repair grainy photos using Photoshop:

  • Launch Photoshop software on your device and open the image that you need to repair.
  • Go to Filter > Noise > Reduce Noise. Now, you will get a Reduce Noise pop-up window with various options: Strength, Sharpen Details, and Preserve Details, on your screen.
  • Adjust these settings until you find the image is fixed.
  • You can also click on the ‘Remove JPEG Artifact’ box to check the outcome as per the changes.

Once you are done with the above changes, click the OK button to save the edited image. 

Method 03: Use Adobe Lightroom to Reduce Noise

Lightroom is also a useful software application that you can use to reduce the graininess of your image. Here are the simple steps that you need to follow to fix grainy JPEG images using Lightroom:

  • Firstly, open the Lightroom app on your system and open the photo you need to repair.
  • Select the ‘Detail’ option in the right navigation pane.
