How to remove the "noise in the photo" in Photoshop

How to remove the "noise in the photo" in Photoshop

In this lesson we will figure out step by step, how to reduce the noise in Photoshop, using the plugin Noiseware Professional. 

This method of the struggle with the digital noise can not be compared to standard possibilities of the Photoshop.

The struggle with the digital noise is the most relevant to the images made with the help of the compact digital camera and with the high values of ISO or long exposures. With your permission I will not return to the definition and causes of the appearance of the digital noise, I wrote about it in the article "Digital noise in the photograph".

 

How to remove noise effectively in the Photoshop 

 

With the reduction of noise in the post-processing mode, the final result directly depends on excellence of processing algorithms, because the wrong recognition of noise results inevitably in the loss of small details, so eventually we can see "the plastic effect".

 

Effective method of struggle with the noise

 

At the time, I had a question, how to remove noise in the Photoshop, while preserving the maximum of details. As a solution I propose to apply the plagin Noiseware Professional, which installs in the Photoshop. 

 

For understandable reasons, I can not give you the downloading link to the plagin, but I will tell you what I did.

 

Go on the Google and type a query "to download Imagenomic Noiseware Professional", the first three answers are working, it’s checked. So download and install the plagin, if you have the questions with the installation, ask me for a help.

 

Then download the photo to the Photoshop and go on!

 

Step 1

 

After installation of the plagin "Noiseware Professional", call it using the panel Filter

Filter > Imagenomic > Noiseware Professional

 

In the opened panel of the plagin Noiseware Professional we well make the following settings, corresponding to the plan of our composition. 

 

First let’s study 3 modes which are used for the editing of different plots.

 

1.Landscape - the algorithm of editing is optimized for landscape theme, photos of nature.

 

2.Night Scene - this mode allows to struggle optimally with the digital noise in the photos made at night, where higher values of ISO (sensitivity matrix) were used with a long exposure.

 

3.Portrait - this mode is optimal for such scenes, where people are present, because it provides the best recognition of skin color.

 

 

Step 2

 

As the main element of our scene is a person, the most appropriate mode for editing is the Portrait mode.

 

Go to Settings > Portrait

 

Pre-installed "Portrait"  has showed an excellent result in the automatic mode.

 

If we are satisfied by everything, validate the result by pressing the button OK.

 

Step 3

 

Fine tuning of plagin Noiseware Professional 

 

The mode of noise reduction, optimized for a portrait shooting, did a great job, but if you want to improve the result for a certain composition, I propose you to delve into fine tuning of plagin.

 

If the scene, that we edit, contains a high level of digital noise, after the reduction of noise we will probably need the compensation with the help of the following settings. 

 

In the settings panel we activate "Detail", which is responsible for the detailing of the composition.

In the group Detail Enhancement there are settings which help to optimize sharpening and contrast of details of the composition.

I emphasize that the settings values may vary for different compositions, but in this case we have such kind of settings.

 

Option Frequency allows to control the intensity of influence on the noise grain diameter ( high - fine grain, low - large grain), for easier understanding I drew deliberately a rough analogy. This settings section is almost never used by me, but in order to inform you I post a screenshot.

 

With the help of settings Tonal Range, we can produce a fine setting of noise reducing filter with shadows, midtones and highlights.

 

The last instrument Color Range gives us a possibility to control the noise in a color range.

For example : in our case yellow color has a minimum level of noise, so we reduce the intensity of the influence of the filter only on the yellow color.

Step 4

 

When it’s necessary to save individual settings under its own name, perform the following action :

 

Call the panel Save Custom Filter Sittings by the combination of CTRL+C and in the field

name - set our name and press OK.

 

Then, after receiving the necessary result with the help of these settings, press the button OK

 

In completing of the editing we save our file

File > Save As 

 

 

Evaluate the result of editing of the file with a wittingly high value of noise after Noiseware Professional. 

 

Noise reduction is based on a work of the plagin - Noise Professional 

The next image demonstrates the possibilities of  the build-in algorithm of noise in the Photoshop - Reduise Noise

With the reduction of the noise in the next image we also use the plagin Noiseware Professional.

To sum up :

In this lesson I showed you how to struggle effectively with the noise in the Photoshop, receiving a result, superior to the build-in algorithms of noise reduction. 

 

It is important! The main rule we should stick to : never delete the noise completely, because you have a risk to receive a plastic effect.
