![]() The conundrum of reducing noise in a photo is that by smoothing out the jagged, spotty edges in an image, you lose the detail that those spots were representing. Tips for Reducing Photo Noise When Shooting It’s just a matter of not having enough light available to produce a clear, sharp image, so the sensor or film reproduces the image imperfectly. Luminance noise shows up not only in digital images but also in film photography, where it’s usually referred to as grain. The latter is unique to digital photography, and it’s the most unpleasant form. There are two main kinds of noise that photo-editing programs usually address: luminance (light) and chroma (color). Many cameras take a dark exposure immediately after a long exposure photo in order to better control noise. Night sky photographers and others who are interested in making photos with long exposure times will contend with heat buildup.

You'll see it in unedited raw format images as splotches of false color, along with a rough, grainy texture, evident in the image below. As such, we tend to think of noise as a problem for low light situations more than for brightly-lit scenes. Noise tends to show most when the sensor is set to a high ISO, the numerical measurement of light sensitivity. In fact, all digital photos have some noise, but the camera and photo software can usually remove most of it. Noise can sap photos of fine detail and harm color accuracy, but it's not impossible to remove. Conceptually it is not that different from film grain, especially since the false color aspect is relatively simple to remove with raw processing software. In digital systems, noise pops up in pictures in the form of false color and rough texture. You'll be amazed at how much better photos look after running them through the denoising steps below: They can turn even unusable shots into ones you can be proud of! These tricks can even be used on old photos from cameras with less-than-great noise characteristics-or even on scanned film photos with too much graininess-to make them look like you shot with a newer model. Here we’ll explain what photo noise is, how to avoid it when shooting, and how to nearly get rid of it in editing using either Photoshop or specialty photo-editing software that’s better at denoising photos than Photoshop. You’ve seen it before: a photo shot at night or in low light that’s distorted with a random pattern of speckles.
