Why Are My Photos Grainy?
Why are my photos grainy? The streets are bathed in a golden glow that makes you just want to be photographed. But when you review your photo later, you see that the sky is black and the shadows look grainy. Read: why my photos are grainy This is a common problem and can be difficult to fix, which is why we’re here to help.
Why does digital noise occur?
Contents
Every digital camera has a sensor that replaces the old film. These sensors receive light and convert it into pixels in your final image, via tiny photo diodes. Sometimes these pixels measure the light received by the sensor incorrectly, especially when your sensor gets hot. The result is digital noise, speckles on your photos that give an overall impression of graininess.
High ISO

You or your camera may not want to detract from the scene with the flash and may instead compensate by increasing the ISO. ISO determines the sensitivity of the sensor. A higher ISO can capture more details in dark photos without having to use the flash. With newer camera models, you can enjoy reasonably high ISOs with little noise in your images. But as a rule of thumb, in general, the higher your ISO, the more noise your camera produces. The easy fix is to lower the ISO. The lower your ISO, the less noise your photo will have. But sometimes that is not possible. So here are some tips to help avoid grainy photos while keeping ISOs high:
Over used
This is one of our favorite photography tricks. Overexposing an image can really reduce the amount of noise you’ll get. You can always edit the images in post-production, but give it a try and you might find it’s your new favorite trick too!
Use noise reduction
Thankfully, many higher-end cameras now offer noise reduction settings. In this setting, your camera looks for unusual pixels and corrects them. It reduces noise by softening the image, but be careful: you may lose small details as a result.
Introducing more light

But brightening your image will help reduce shadows and any potential noise. You can introduce a new light source, whether it’s a lamp or a flash, to improve the lighting in your area.
Enthusiastic post-production
There are a few things you can do in post-production that can increase noise in your images. Some things you can do in your digital production program that will emphasize graininess include:
- Zoom and crop
- Increase the ball
- Increase exposure
- Increase sharpness

Camera quality
If the low-light quality of your images is really bothering you, it might be time to upgrade your camera. Older cameras or those with small sensors may not be able to take high-quality, low-light images. Newer, higher-end cameras often have larger, more sensitive sensors, which means they can perform much better in low-light situations. Large-sensor DSLRs or compacts are usually the best choices, especially if they have a full-frame sensor like the one on the Canon EOS 5D Mark III or Sony Alpha A7. that can bring more light to the sensor.
