Part 1. What Causes Digital Noise?

Digital noise is a common issue that can occur in photographs due to various factors. It is caused by using a high ISO setting, shooting in low-light conditions, or using older camera models. Understanding the causes of digital noise is crucial to address this problem effectively.

☞ Two Main Types of Photo Noise

• Colour noise: Colour noise manifests as unwanted coloured pixels scattered randomly throughout an image. These specks of colour can be distracting and make the image appear less sharp and clear.
• Luminance noise: Luminance noise appears as grainy or speckled patterns of brightness variations. It can make your image look rough and less refined, especially in areas with low light or high ISO settings.

☞ Possible Factors Causing Noise Photo

• High ISO Settings: Higher ISO settings amplify the sensor's signal, but they also amplify noise, especially in darker areas of the image.
• Low Light Environment: When shooting in dim lighting, cameras increase the ISO sensitivity to capture more light, which can introduce noise.
• Over-exposure: Prolonged exposure can cause the camera sensor to heat up, leading to increased noise, particularly in long-exposure photography.
• Incorrect/Excessive Image Processing: The algorithms used to process images can sometimes introduce noise, especially if they attempt to enhance details in low-light conditions.
• Smaller Sensor: Cameras with smaller sensors (like those in smartphones) tend to produce more noise compared to larger sensors (like those in DSLRs) due to less light capture.

Both colour and luminance noise resulting from the above reasons can degrade the overall quality of your photos, making them appear less professional and polished. Therefore, addressing this issue and reducing noise is important to achieve cleaner and more visually appealing images.

Part 3. How to Reduce Noise in Photoshop [3 Ways]

After walking through the overview of the 2 popular denoise techniques in Photoshop, now, let's begin to apply them to remove noise with Photoshop:

Method 1. Use Reduce Noise Filter - Basic Mode

If your image has noise all over it, the Basic Mode of the Reduce Noise filter can be a useful starting point and get the answer to how to reduce noise in Photoshop. This method can also be applied to sharpen images in Photoshop

• Begin by duplicating the image and converting it into a smart object. Then, open the 'reduce noise' filter, following the steps outlined in the earlier part of this tutorial. The filter will open in its default basic mode with various sliders.

  

• The primary slider is labeled 'strength,' you can adjust it to eliminate noise. Since the image contains a significant amount of noise, we will select the maximum value of 9 (the highest available is 10).

  

  The 'preserve details' slider complements the 'strength' slider by refining its effect. When reducing noise excessively, there is a risk of losing important details. Given the severe noise in my image, I will choose a value of 3%.

  

  You can employ the 'reduce color noise' slider if you observe any color noise in your image. In my image, some color noise is near the stars, so I will select 45%.

  

  It is important to exercise caution when adjusting the 'sharpen details' slider since setting it to high values may reintroduce noise. For my image, I will opt for a value of 8.

  

• After editing, click 'OK' to return to the canvas. The resulting image, after applying the 'reduce noise' filter, should appear as follows:

  

Method 2. Use Reduce Noise Filter - Advanced Mode

You can utilize the Advanced Mode of the Reduce Noise filter for more control over noise reduction and get the answer to how to reduce noise in image Photoshop.

• Duplicate the image layer by selecting it and pressing "Ctrl+J" (Windows) or "Command+J" (Mac).

  

• Convert the duplicate layer into a smart object by right-clicking on the layer and choosing "Convert to Smart Object." This ensures non-destructive editing.

  

• With the duplicate layer selected, go to the top menu and choose "Filter" > "Noise" > "Reduce Noise." The Reduce Noise dialogue box will appear.

  

• Set the zoom level to 100% in the Reduce Noise dialogue box to see the noise details.

  

• On the right side of the dialogue box, you'll find two options: Basic and Advanced. Select the Advanced mode for more precise noise reduction.

  

• In Advanced mode, you can remove noise per channel (red, green, and blue). Analyze the image and identify which channel has the most noise. Adjust the sliders for each channel to reduce noise selectively.

  

• Experiment with the sliders and find the balance between noise reduction and preserving details. Be mindful not to overdo it, as excessive noise reduction can result in losing important image elements.

  
• Once the noise reduction adjustments are satisfied, click "OK" to apply the changes.

Method 3: Use Camera Raw Filter

Another effective approach to reduce noise in image Photoshop is utilizing the Camera Raw Filter.

• Open the image you want to edit and duplicate it. Convert the duplicate layer into a smart object for non-destructive editing.

• Go to the top menu and select "Filter" > "Camera Raw Filter."

  

• Set the zoom level to 100% for accurate noise assessment in the Camera Raw dialogue box.

  

• Enable the "Before and After" view mode by clicking the small square icon at the bottom of the panel. This allows you to compare the edited version with the original image.

  

• Navigate to the "Detail" panel on the right side. Here, you'll find options for reducing noise and enhancing details.

  

• Adjust the "Noise Reduction" slider to reduce noise. Avoid pushing it too high to maintain a natural look. Move the "Detail" slider slightly to recover some lost details, but avoid reintroducing noise.

  

• If reducing noise affects the contrast, use the "Contrast" slider to restore it. Find the appropriate balance for your image.

  

Notes

Use the "Color Noise Reduction" slider for colour noise reduction. The "Detail" slider helps recover lost details, while the "Smoothness" slider softens areas affected by color noise. Experiment with the sliders until you achieve the desired result. Remember that the optimal settings may vary depending on the specific photo.
