How to fast denoise a photo without effort
Posted On April 9, 2021
Photographers may come across such an issue when taking a photo. After shooting a scene, you will see tiny and dark spots in your photo. These spots create grainy photos and are referred to as noise in digital photography. There are some reasons leading to it. You raise the ISO level to capture more light when you are shooting in the low light. The high ISO makes the sensor of the camera group pixels together, which results in a gritty and noisy look. In short, the higher the ISO setting is, the more noise you will have in your photo. Long exposure is another cause of noise. As the exposure becomes longer, the sensor of the camera gets hotter. The heat contributes to noise in the final photo. Underexposure is also a contributor to noise. If you take an underexposed photo, you will find the noise is noticeable in the darker regions of the photo. The uneven grainy look resulted from the noise dramatically lowers the quality of your photo. If you are experiencing this problem and wondering how to denoise a photo, please continue reading this article. In this article, I'll show you three methods to remove the noise from a photo using noise reduction software.
Method 1. Remove the noise from a photo with Photo Effects
Overview of Photo Effects
As the name implies, Photo Effects is a piece of professional photo effect software. With a variety of parameters and decorative objects, it lets you enhance the quality of your photos to make stunning photos with ease.
You will be greeted by a simplistic window after you launch the program. This window consists of three panels. A collection of predefined effects are located in the left-side panel. When the photo is loaded into the program, you will see small preview thumbnails of these predefined effects. The middle panel takes up most of the window. This is where you can preview the effects applied to the photo. You can compare the original photo, zoom and pan the photo, and discard all changes you make. There is an assortment of adjustment parameters in the right-side panel. You can change the exposure compensation, exposure compression, lightness, saturation, and contrast. You can adjust the shadows/highlights, dynamic range, tone mapping, and white balance. Other parameters you can adjust include local contrast, vibrance, channel mixer, soft light, and vignette filter. You are also given the possibility to reduce the noise level in the photo and sharpen the photo.
On the whole, Photo Effects is a simple yet powerful photo effect app that offers a comprehensive photo editing suite. It allows you to quickly process your photo using built-in fine tuners and add special effect to your photo. If you wish to improve the quality of your photo, Photo Effects is a great go-to option.
