How to Repair a Grainy Photo?

How-to-Repair-a-grainy-photo

Are you also a victim of grainy photos which contain spots, lack colour, and sharpness? Don’t worry, there are ways you can fix grainy photos, even if the noise is in abundance.
Noise is one of the common challenge faced by the photographers and editors, whether professionals or amateurs. Most of the time it does not affect the picture quality but when you zoom in, the photo appears to be grainy with small dots all over it. Irrespective of the camera, shooting in low light or at high ISO can often ruin your pictures. But thankfully, this visual distortion can be repaired at the editing stage of the photos.

Why are your Photos Grainy?

There can be one or more reasons that make your photos grainy. These include various photography aspects like ISO, shutter speed, camera specifications, camera exposure or aperture. Below are the prime reasons why your pictures turned grainy:

Light condition – In absence of enough light the pictures turn grainy. For example if your shot is taken at sunset or in a poorly lit room, you were not able to manage a proper low aperture and higher ISO ratio or if you turned on the flash. In such cases, your photos get grainy.

ISO – A simple rule is that greater the ISO of your camera, more the noise or grains in the picture. Increasing ISO is often a necessity when shooting in low light or at night.
It is for you to decide to what extent the noise is tolerable so as to not spoil the sharpness and overall quality of the image.

To put it in simple words, ISO in photography is the sensitivity of your camera’s imaging sensor to the light. If you are using high-end professional cameras, they are designed to produce minimal or negligible noise even at higher ISO of 3000 . Some latest digital cameras are also able to manage picture quality with least noise up to ISO 1000.

Camera type – If the grainy photos problem is persistent with your specific camera, this means your camera has a small sensor. It is not sensitive enough to capture in low light conditions. This is usually a complaint with some point and shoot cameras, low-end DSLR, and smartphone cameras.

3. Reduce noise with Lightroom


Lightroom: Develop module window

Lightroom developed by Adobe is also a photo editing software that comes with photo noise reduction feature.

  • Open the image in Lightroom application
  • Go to Develop module of Lightroom
  • Open the Detail Panel. On the left pane under Noise Reduction you will see Luminarc and Color.
  • Start with Luminarc and adjust the given noise reduction bars – Detail and Contrast, until you get satisfactory grainy image correction. Similarly adjust the sliders under The changes can be viewed on the right pane. Once done save the edited photo.

Lightroom is effective in repairing the grainy and sandy corruptions of the photos. But the drawback is that the correction is applied to the whole image and not just the grainy area on the photo. This might disturb the original settings of your photo.

4. Fix grainy photos using Plugins

If you are already using some photo editing application, buying plugins for noise reduction can be considered. Plugins significantly reduce noise and fix grainy photos. The good part of using plugins is that you can apply the correction only to the selected grainy parts of the photo and not the whole image. Some plugins are even capable of repairing severely damaged pictures. Some commonly used plugins by the professional photographers include Noise Reducer Pro, Noise Ninja, Neat Image, NoiseWare, Photo Ninja, and Topaz DeNoise etc.

You have to experiment and intelligently play with the settings to obtain the acceptable picture quality.

If you are willing to spend a little more, plugins can also be of use to repair grainy photos.
