Sometimes the photos you take will not be clear, but it will be blurred or contaminated or there is not enough light. In this article, Sadesign will help you overcome the above defects by denoising in Photoshop extremely simply.
What is noise in photoshop?
Noise is a grainy image phenomenon if you take pictures in a low-light environment. The image with noise when looking at it will not be smooth, lose its beauty and not be beautiful. But you do not need to worry because there is still a way to fix this phenomenon with Photoshop in the simplest way.
Noise will be divided into the following 3 types:
- Random Noise: this is the form of noise when you take pictures with fast speed, high ISO (light sensitivity) and Noise will be distributed randomly.
- Fixed Noise: Noise will appear when you take pictures in an environment with high temperature, and the time the photo is taken.
- Banding Noise: Noise will appear when the photographer increases the light in the dark areas, and then the noise will have a striped appearance. In addition, banding noise is also highly dependent on the sensor manufacturing technology of the manufacturers.
2 ways to remove Noise with Photoshop very quickly
Method 1: Eliminate Noise with Lab color system
This way has one advantage that you can do it right on Photoshop without having to install any additional applications. However, it will have to go through many operations.
Step 1: Open photoshop software and upload the edited image by: File => Open or you can drag and drop that image into the software.
Step 2: You will convert the image to the Lab system so that you can reduce the Noise on the areas of the Lab color system by: Image => Mode => Lab Color.
Note: In case you have many layers, Photoshop will optionally ask you if you want to change to Flatten image or not? This is the option that will help you merge all the layers together. For the purpose of noise reduction, choose Don’t Flatten!
Step 3: Open the Channel tab (next to the Layer Tab) > Select the Lightness channel and do the following:
Choose Filter => Noise => Despeckle to make the image smoother.
Step 4: At Channel Lightness, select Filter > Noise > Reduce Noise and adjust the parameters (depending on your photo, you can change the appropriate parameters)
Step 5: Switch to Channel a => Filter => Blur => Gaussian Blur
Step 6: In this step you will make noise on channels a and b. And adjust the parameters to balance from about 0.5 – 1 pixel.
Note: because this is a blur parameter, if you set it too high, your image will be blurred. And you do the same for channel b.
Step 7: Return to the layer tab > convert the color system to RGB and you’re done.
Method 2: Use the Noise Reduction Plugin in Photoshop
With this method 2 will help you manipulate faster and simpler, but its disadvantage is that you need to install more applications to do it.
Step 1: Download the plugin at the homepage and log in with your email to download the plugin immediately.
Step 2: Install the Noiseware Plugin on your device
Turn on the downloaded file and install it => Next => Next => Install => Finish
Step 3: After you have installed the plugin automatically in photoshop when you open the application.
Next, you just need the image you want to denoise in Photoshop and access the Plugin according to the following instructions: Filter => Imagenomic => Noiseware.
Step 4: It is an automatic function with self-adjusting parameters, you can also change the parameters if you are not satisfied with the photo in the left column. You can also view the simulation in the Preview pane. After adjusting the noise reduction parameter to your liking, just click OK.
Note: the layer or the image that you need to remove the Noise will be changed without the duplication of the layer, so if you want to restore it, you need to open the history pane.
