Quick Answer: Lightroom AI Denoise is Adobe's AI-powered noise reduction feature designed to remove grain from high-ISO RAW photos while maintaining natural details.
To denoise a photo in Lightroom Classic, open your RAW image, go to Develop > Detail > Denoise, adjust the AI Strength slider, and click Enhance to generate a cleaner DNG file.
High ISO photography often comes with unwanted noise, grain, and loss of fine details, especially when shooting in low light, at night, or with fast shutter speeds. Lightroom AI Denoise provides a convenient way to clean up noisy RAW photos while preserving important textures and details.
In this guide, we'll show you how to use Lightroom Denoise AI step by step, explain the best settings for different photos, and discuss its limitations. You'll also learn when Lightroom's built-in denoising tool is enough and when a dedicated AI image enhancer may be a better choice for batch processing, JPEG enhancement, or additional upscaling.
What Is Lightroom AI Denoise and Where to Find It?
Image noise is the grainy texture or colored speckles that often appear in photos taken with high ISO settings, low light, or underexposed conditions. Too much noise can hide fine details and reduce overall image clarity, especially in night photography, wildlife shots, and other challenging shooting environments.
Lightroom AI Denoise is Adobe's AI-powered noise reduction feature designed to remove unwanted noise while preserving important textures and details. Introduced in Lightroom Classic 12.3 and Camera Raw 15.3, it uses Adobe Sensei technology to analyze images and deliver more natural results compared with traditional luminance and color noise reduction sliders.
Key Benefits of Lightroom AI Denoise:
- Automatically detects and reduces image noise while preserving fine details.
- Works especially well with RAW files and high ISO photos, including images shot at ISO 12800, 25600, or higher.
- Provides one-click AI noise reduction without requiring complex manual adjustments.
- Helps improve low-light photos, night scenes, and older images with visible grain.
Unlike traditional noise reduction adjustments, Lightroom AI Denoise creates a separate enhanced DNG file instead of modifying the original photo. This keeps your original RAW file intact while providing a cleaner image with preserved details and a natural look.
Where Is Denoise Located in Lightroom Classic?
To find Lightroom AI Denoise, open your RAW photo in Lightroom Classic, switch to the Develop module, and open the Detail panel. You will find the Denoise button next to the traditional noise reduction controls.
Lightroom AI Denoise is available in Lightroom Classic 12.3 or later and Camera Raw 15.3 or later. If the Denoise option does not appear, check your Lightroom version, supported file format, and system requirements.
How to Use AI Denoise in Lightroom Classic
Once you know where to find Lightroom AI Denoise, the next step is applying it correctly. The workflow is simple: import your photo, open the Denoise panel, adjust the AI Strength setting, and let Lightroom create an enhanced DNG file with reduced noise and preserved details.
Step-by-Step Guide to Lightroom AI Denoise
Follow these steps to denoise photos in Lightroom Classic:
Step 1. Import your photo into Lightroom Classic.
Lightroom AI Denoise works best with RAW images, especially high-ISO photos captured in low-light conditions. Import your image and select the photo you want to enhance.
Step 2. Open the Develop module.
Switch to the Develop module, where Lightroom provides access to editing and enhancement tools.
Step 3. Open the Detail panel and select Denoise.
In the Detail panel, click the Denoise button. Lightroom will generate an AI preview showing how the noise reduction will affect your image.
Step 4. Adjust the AI Strength slider.
The Strength slider controls how aggressively Lightroom removes noise. Adobe sets the default value around 50, which works well for many images. Increase the value for heavily noisy photos or reduce it when you want to preserve more natural texture.
Step 5. Preview the result and click Enhance.
After adjusting the settings, preview the result at 100% zoom to check noise reduction and detail preservation. When satisfied, click Enhance to apply Lightroom AI Denoise.
Step 6. Check the enhanced DNG file.
Lightroom creates a new DNG file with AI Denoise applied while keeping your original RAW file unchanged. The enhanced image appears next to the original photo in the filmstrip, allowing you to compare both versions.
Best Lightroom AI Denoise Settings
Lightroom AI Denoise does not have a universal best setting for every photo. The ideal Strength value depends on ISO level, lighting conditions, and how much detail you want to preserve. Use the following settings as a starting point and fine-tune them based on your image.
For the most accurate evaluation, preview your image at 100% zoom. A higher Strength value removes more noise but may also reduce natural textures in some photos.
Besides AI Denoise, Lightroom also offers traditional noise reduction controls in the Detail panel for additional fine-tuning. These manual adjustments are useful when you need more control over the final look.
- Luminance: Reduces brightness noise but may soften details at higher values.
- Color: Removes color speckles caused by high ISO shooting.
- Detail and Contrast: Help restore texture and edge definition.
For most high ISO RAW photos, start with Lightroom AI Denoise and adjust Manual Noise Reduction only if needed.
Lightroom AI Denoise Results: Before and After Examples
Lightroom AI Denoise is especially useful in situations where photographers need to shoot at high ISO settings, work in challenging lighting conditions, or preserve details from noisy RAW files. The following examples show how AI Denoise can improve common photography workflows.
1. Wedding Photography: Reducing High ISO Noise from Wedding Portraits
This wedding portrait was captured outdoors during a late afternoon ceremony using a Canon EOS R6 with a 50mm f/1.2 lens at ISO 12800. In the low-light environment, the photographer used a wide aperture to create a soft background blur while raising the ISO to maintain proper exposure. However, the original RAW image showed visible noise in shadow areas and skin tones, affecting the overall portrait quality.
After applying Lightroom AI Denoise, the image became cleaner while preserving natural skin texture, facial details, and the smooth background blur. The reduced noise helped create a more refined wedding portrait without making the image appear overly processed.
For photographers processing hundreds or thousands of wedding images, Lightroom AI Denoise’s batch workflow can also help speed up noise reduction before further adjustments.
2. Wildlife Photography: Improving Noisy High ISO Animal Shots
This wildlife photo was captured in a dark zoo environment using a Sony A7s with a Leica 50mm APO lens at ISO 64000. Due to the extremely high ISO setting, the original image contained heavy luminance noise, especially in the dark background, which affected the visibility of fine fur details.
After applying Lightroom AI Denoise, the image showed a significant improvement. Background noise was reduced while maintaining natural textures, and details in the squirrel’s fur appeared cleaner and more defined without an overly smoothed look.
However, noise reduction cannot fully restore details that were never captured. For heavily cropped wildlife photos or images that need higher resolution output, additional AI enhancement may be needed after denoising.
3. Astrophotography: Cleaning Up Noise in Night Sky Images
This Milky Way photo was captured at night using a Sony A7 III with a 20mm wide-angle lens at ISO 6400 with a 20-second exposure. To capture enough light from the stars in a dark outdoor environment, the photographer used a high ISO setting, but the original RAW image showed noticeable luminance noise and color noise across the sky, reducing the clarity of faint stars and the Milky Way details.
After applying Lightroom AI Denoise, the image showed a cleaner night sky while preserving star details and natural textures in the landscape. The reduced noise helped improve overall clarity without making the stars or sky appear artificially smooth.
Lightroom AI Denoise Tips and Troubleshooting
Lightroom AI Denoise is designed to simplify noise reduction for RAW photos, but some users may encounter issues with availability, processing speed, or batch workflow. The following tips can help you get better results and troubleshoot common problems.
Why Is Lightroom AI Denoise Not Working?
If Lightroom AI Denoise is unavailable or fails to process your image, check the following possible causes:
- Unsupported file format: Lightroom AI Denoise works best with RAW files from supported cameras. Some formats, such as JPEG, TIFF, or already processed images, may not support AI Denoise.
- Outdated Lightroom version: Make sure you are using the latest version of Lightroom Classic or Lightroom with AI Denoise support enabled.
- GPU acceleration issues: AI Denoise relies on GPU processing. Update your graphics driver and check Lightroom’s Performance settings if processing fails or becomes extremely slow.
- Insufficient system resources: Large RAW files require significant memory and GPU resources. Close unnecessary applications and try processing the image again.
- Already processed images: AI Denoise is designed for original image data. Images that have already been heavily edited, exported, or converted may not produce optimal results.
If Lightroom AI Denoise still does not work, try creating a new Smart Preview, updating Lightroom, or testing with another supported RAW file to identify whether the issue is related to the image or the software.
Can Lightroom Denoise Multiple Photos?
Yes. Lightroom AI Denoise supports batch processing for multiple RAW photos. To denoise multiple images, select the photos you want to process, go to Photo > Enhance, enable Denoise, adjust the Strength value, and click Enhance. Lightroom will create a new enhanced DNG file for each selected photo. Processing time depends on your computer’s GPU performance, image resolution, and the number of photos selected.
Note that Lightroom’s traditional noise reduction controls in the Detail panel can also be synchronized across multiple photos, but they work differently from AI Denoise and do not use Lightroom’s AI processing.
Batch processing is useful for large photo collections, such as wedding, wildlife, or night photography shoots. However, processing time depends on your computer’s CPU, GPU, and the number of selected images.
