How to get rid of the noise from a digital photo
Posted On June 4, 2021
As a photographer, you may come across such an issue. You take a shot of a scene and the photo ends up being grainy. This is so-called noise in digital photography. This result is caused by different factors. When shooting in a low-light situation, you will raise the ISO level. The high ISO will tell the camera's sensor to group pixels together to capture more light. Grouping pixels results in a noise photo. If you shoot a long exposure, your camera will get hot and the heat will produce noise in the photo you get. When a photo is underexposed, the noise in the dark parts of it will become more visible. Then, how to cope with such a problem? Thanks to the development of photo post-processing technology, we have photo effect software that is able to iron out this issue. If you are looking for reliable photo effect editors to help you get the job done, please continue reading this post. In this post, I will introduce you to two software tools you can use to get rid of the noise from your photo.
#1. Photo HDR
As the name implies, Photo HDR is a piece of professional software to make HDR photos. But what Photo HDR is capable of doing is more than that. Bundled with a wide range of easily-accessed parameters and decorative objects, it enables you to enhance the visual aspects of the photo to get gorgeous photos.
Fire up the program and you will be welcomed by a sleek and clean window. Once three photos of the same scene with different exposures are imported into the program, they will be merged into one single HDR photo. Click on "Next" and you will be taken to a new window. This is a window where you can adjust the effect of your photo. The window is divided into three panels. A set of preset effects are located in the left-side panel. You can see the small preview thumbnail of each effect. The middle panel takes up most of the window. It is a preview area where you can see the result of making any adjustment to the photo in real-time. A variety of parameters are located in the right-side panel. You can change the brightness, contrast, and saturation to adjust the exposure. Moreover, you can modify the local contrast, compress the dynamic range, and tone-map the HDR photo. What's more, you are given the possibility to increase the sharpness of the photo, denoise the photo, and use Lab adjustment to boost colors. Furthermore, it is possible to add a graduated filter effect to the photo. Vignette filter, vibrance, and soft light are other parameters.
All in all, Photo HDR is a powerful photo processing app with two functions. Firstly, it combines differently exposed photos to quickly make a HDR photo. Secondly, it allows you to enhance the photo quality with one-touch adjustment. Owing to the minimalist layout and intuitive settings, Photo HDR can be easily mastered by both novices and experts. If you want to make your photos look great, Photo HDR is definitely what you should go for.
Now, let's dive into the part of how to reduce the noise in a photo with Photo HDR
How to use Photo HDR to reduce the noise in a photo
- Throw your photo into the working space saying "Drag and Drop Your Photo here". You can also import the photo by clicking on the "Add" button. To remove the imported photo, click on the "Remove" button next to the "Add button".
- Click on "Next". Go to the right-side panel and scroll down to the "Noise Reduction" section". Click on the "Noise Reduction" button to activate the function of adjusting the parameter. The parameter in this section is gamma. It is used to vary the strength of the denoising effect across the range of tones. As the value is decreased, darker tones will be affected by the denoising effect. As the value is increased, brighter tones will be affected by the denoising effect.
- Drag the slider to adjust the effect until it suits your needs.
- Press the "Save as" button to export the photo to a desired location.
Tests indicate Photo HDR does a great job of reducing the photo noise. Since it is a piece of commercial software, the free version leaves a watermark to the exported photo. To get a changed photo without the watermark, upgrade the free version to the pro version. Perhaps you want a free application. That's why I will introduce PineTools to you in the following part.
PineTools is one of my favorite online image manipulators. With the help of it, you can edit your image in an around way. Let's say, you can lighten and darken the color of the image, change the color saturation, resize the image and flip an image horizontally and/or vertically. Let's see how to remove the noise from a photo with PineTools.
