How To Fix Grainy Photos

Grainy, noisy photos are just a fact of any photographer’s life. They can happen regardless of what kind of camera you’re using and are especially common if your photography involves a lot of low light shooting.

Sometimes noise can make retro-looking effects that look great if done right. However, graininess can be a problem that should be addressed if it is possible.

Fortunately, most unwanted noise in photos can be easily fixed through several different software editing solutions, so don’t despair yet.

You can follow the steps and suggestions to avoid graininess and fix it if you do.

What Causes Grainy Pictures?

Graininess in digital camera shooting is also known as digital noise, or just “noise”, and it can be caused by multiple factors. Most of these revolve around the following:

  • Luminance noise: The single biggest cause of image noise is poor luminance, mainly from setting the ISO too high or wrong for a low light shot. All cameras can suffer this problem regardless of their price, but it’s especially common in those with less than exceptional ISO performance. The camera sensor will make any light signals it captures more prominent to compensate. This results in excessive noise.
  • Color noise: Color noise isn’t caused by lighting conditions so much as being a product of an overheated sensor. This can be seen in long exposure photos that were taken in low light, or in time-lapse photography. This is often seen in dark scenes and can be described as a form of blotchiness.
  • Sensor size: Grainy photos can happen in any camera if its capacity for light absorption is stretched to the limit or if its settings are improperly calibrated, but there is a definite connection between graininess and smaller sensors with lower resolution. Full format sensors of high quality have many millions of light-absorbing pixel to compensate for low lighting. These sensors also tend to have high ISO sensitivity.
  • Low exposure: An underexposed photo can be a very noisy photo and sometimes the graininess is caused by using the wrong exposure setting for your composition.

Filter noise can also happen if you’re using filters, and noise from any of these causes can also be worsened by improper focus or shooting photos from a distance.

These problems are usually simple and can be fixed with simple solutions. Make sure you focus your camera properly, and get closer to your subject whenever possible.

Preventative Solutions

Right off the bat, the best way to fix grainy photos is by avoiding them in the first place. This will save you time and effort later.

That’s right. Overexposing your photos is not only a problem in many cases, but it can also help to prevent graininess. To make this work, avoid raising your camera’s ISO settings, since doing this will just create the risk of more digital noise.

Instead, increase your exposure by one stop and use an increased aperture to take a photograph. This can be used to slow down your shutter speed, but this may not work well for low light shots of subjects moving.

Check out our guide on overexposure vs. underexposure.

Using a lower ISO

Using a low ISO will help you avoid having to fix grainy images.

Lowering your ISO settings won’t necessarily work if the ambient darkness of the scene you’re trying to capture is too deep, but lower ISO does usually mean less noise.

It is possible to lower the ISO by increasing the aperture and shutter speed.

Metering the shot onto the brightest possible object

Setting your focus to the brightest possible object in your composition and taking a photo with the camera metered to this particular luminous point can also improve brightness and reduce noise.

It can help the camera avoid overextending itself when capturing details from dark areas of a scene.

For more information, see our guide to metering.

Activating noise reduction

Not all cameras have a noise reduction setting built into their controls but, if yours does, it can be a handy in-camera tool for eliminating grainy photos.

The option to reduce noise will vary from device to device but try activating it and setting noise reduction to a low or moderate level to avoid detail loss

Taking photos in RAW

Take photos in Raw format to fix grainy image issues.

The RAW image format is much more versatile for correction and details than JPEG, which is compressed inside the camera to begin with.

Thus, if you’re unsure about the quality of the pictures you plan on taking, setting your digital mirrorless or DSLR camera to take both a RAW and a JPEG shot of your compositions is a useful tactic, for noise correction and for general versatility.

Working with more light

Even with a high ISO for your photos you can fix grainy image problems.

This is probably the most obvious preventative solution on this list but it deserves mentioning. If you want to avoid graininess in the first place, see if the photo scenarios you’re working in can be augmented by more light.

Some photographers hate using flash for their work (I’m definitely one of them) but other more subtle lighting devices like a reflector or soft box might work in some settings.

External flashes can be very useful, provided they are used properly and the light can be diffused so as to not expose too much.

Obviously, you can’t always work with more light. Sometimes, you have to make the most of the digital camera you have. This is why you need to fix grainy photos or noise in post-production.

Fixing Graininess With Photoshop

If you still have noise in your photos, your next step is going to be a software fix. Let’s start with fixing grainy photos in Photoshop, one of the best-known photo editing programs in existence.

Step 1: To reduce noise in Photoshop, you need to launch your edition of the software, select and import the photo you think looks grainy, and then zoom in by 100% with the magnifying lens to confirm how much noise is in the details of the photo.

Reducing noise in photoshop lets you fix grainy photos and save photos that you thought were lost.

Step 2: Click on the Filter menu at the top of the Photoshop application and drop down to Noise. Next, select Reduce Noise. You will see a pop-up window with sliding controls to do this.

There will be three sliders available: one to reduce noise and one to sharpen details. One is for preserving details. Tweak each of these to the left or right until you you’ve sharpened your photo as much as possible.

Step 3: If you still don’t like the Photoshop noise reduction you see, open the Shake reduction tool by clicking on Filter > Sharpen, and then select Shake Reduction. You can use this tool to check if blur caused from a slight shake at the time the photo was taken is possible. If so, you will be able to sharpen your image.

Using Lightroom To Repair Grainy Photos

Lightroom is Photoshop’s leaner cousin from the Adobe family of software products. While the two programs look very similar, Lightroom offers more image manipulation tools.

For reducing noise in Lightroom and cleaning up high ISO, you’ll only need to use a small selection of this program’s tools.

Step 1: Open Lightroom and import your photo to open it up. To the top right of the photo, you’ll see several menu options. Click on Develop.

Step 2: On the right panel, you’ll see several options. Scroll down to Detail and click on it. In here, you’ll have several slider options for photo sharpening and noise reduction.

Step 3: The sharpening and detail sliders can also be adjusted to clean up your photo, but for noise reduction, the sliders for Luminance, Detail, Color and Contrast will adjust the levels of noise caused through these respective characteristics.

You should keep in mind that setting these values at lower levels can cause you to lose fine visual details.
