AI-Powered Noise Reduction in Lightroom: A Game Changer for Underwater Photography

Copywrite - Robert Herb Photography

You're not alone if you’ve ever captured an incredible underwater moment only to find it riddled with unsightly digital noise obscuring your shot's beauty. As underwater photographers, we often navigate complex conditions such as low light, high ISOs, and the persistent challenge of backscatter, all of which contribute to grainy, noisy images that do not do justice to the stunning marine life we seek to document. 

 

For years, we’ve relied on manual noise reduction techniques in Lightroom, delicately balancing the fine line between reducing noise and preserving the minute details that make underwater photography so captivating. Manual adjustments often require a keen eye and endless tweaking to achieve that perfect balance; it’s a meticulous process that can test the patience of any photographer. 

 

However, Adobe’s introduction of the latest AI-powered Denoise tool revolutionizes noise reduction. Unlike traditional noise reduction methods, which can sometimes blur details or create unnatural image artifacts, the Denoise AI leverages advanced algorithms to intelligently eliminate noise while maintaining sharp details and vibrant colors. This represents a significant breakthrough for underwater shooters, who understand how crucial it is to retain the essence of their subjects in challenging photographic environments.

 

In this article, I’ll guide you through five effective noise-reduction techniques tailored for Lightroom. Each method is accompanied by precise steps, handy keyboard shortcuts, and expert tips designed to elevate your underwater photography. Whether you’re a seasoned pro or just starting out, these techniques will empower you to enhance the quality of your images and make the most of every underwater adventure.

Why AI-Powered Noise Reduction Is a Must for Underwater Photography

In earlier versions of Lightroom, noise reduction tools were relatively basic, utilizing straightforward sliders for adjusting luminance and color noise. These controls allowed photographers to minimize grain appearance in their images, which was particularly beneficial in low-light scenarios. However, while these tools achieved some smoothing, they had significant drawbacks. One of the most notable issues was the tendency to blur fine textures. This blurring effect was especially problematic for marine life images, as it could render natural details, such as the intricate patterns of fish scales or the delicate features of corals, to look overly smooth and artificial. As a result, the realism and vibrancy of underwater photography were often compromised, prompting a demand for more advanced noise reduction methods that could preserve the integrity of fine textures while effectively reducing noise.

How AI-Powered Denoise Stands Out:

✅ Removes noise while preserving fine details (scales, coral textures, fish eyes)
✅ Works best on high-ISO RAW files (ISO 1600+)
✅ No third-party plugins needed; now seamlessly integrated into Lightroom
✅ Generates a new DNG file with improved clarity

If you’ve been struggling with noisy underwater shots, AI-powered Denoise in Lightroom Classic is the solution you’ve been waiting for.

1. Using AI Denoise for High-ISO RAW Images (Best for Deep Water & Low Light Shots)

Adobe’s Denoise AI is perfect for high-ISO images shot in dark or murky water. Unlike older noise reduction methods, AI Denoise keeps fine details intact, making it a must-use tool for deep wrecks, caves, or night dives.

How to Use AI Denoise in Lightroom:

1. Open your image in the Develop Module (D)
2. Scroll to the Detail Panel
3. Click Denoise
4. Adjust the Denoise Amount Slider
• 🏊 50-70% for deep water shots with heavy noise
• 🌊 30-50% for mild noise reduction
5. Click Enhance—Lightroom will process the image and create a new DNG file
6. Compare the before/after result

📌 Shortcut Tip: Press Z to zoom in and inspect details before applying Denoise AI.

2. Classic Noise Reduction (For Moderate Noise Without AI Processing)

If your image doesn’t require complete AI-powered processing, you can still reduce noise using Lightroom’s traditional noise reduction sliders. This method is excellent for images with mild noise where AI denoising might be overkill.

Steps to Apply Classic Noise Reduction:

1. Enter the Develop Module (D)
2. Open the Detail Panel
3. Under Noise Reduction, adjust:
• Luminance Slider (Start with 25-40 for light noise)
• Detail Slider (Increase to recover texture)
• Contrast Slider (Fine-tunes results)
4. Adjust Color Noise Reduction if needed
5. Compare before/after

📌 Shortcut Tip: Hold Alt (Option on Mac) while moving the Luminance Slider to see how it affects the image in real time.

3. AI Super Resolution + Noise Reduction (For Extreme Crops & Large Prints)

Ever taken a shot that was slightly too far away? Maybe a shark in the distance or a shy octopus? Super Resolution AI, combined with Denoise, can help.

How to Use AI Super Resolution + Denoise:

1. Right-click your image in the Library Module
2. Select Enhance (Ctrl + Alt + I / Cmd + Option + I on Mac)
3. Check Super Resolution
4. Apply AI Denoise
5. Click Enhance. Lightroom will create a high-resolution DNG file

📌 Shortcut Tip: Use F for full-screen mode to inspect details before and after processing.

4. Mask-Based Noise Reduction (Targeted Adjustments for Backgrounds or Selective Areas)

Not all parts of your image need the same level of noise reduction. Masking in Lightroom lets you apply noise reduction selectively, perfect for reducing noise in darker backgrounds while keeping your subject crisp.

How to Apply Selective Noise Reduction:

1. Open the Develop Module (D)
2. Click the Masking Tool (Shift + W)
3. Select Select Subject or Select Background
4. In the Noise Reduction Panel, increase the Luminance Slider
5. Adjust the Detail & Contrast sliders to fine-tune the effect
6. Click Done

📌 Shortcut Tip: Press O to toggle the mask overlay to see which areas are affected.

5. AI Noise Reduction in Lightroom Mobile (For Editing On-the-Go)

Editing your underwater shots on your phone or tablet? Lightroom Mobile now includes AI-powered noise reduction, making it easy to clean up images before sharing them on social media.

Steps for AI Noise Reduction in Lightroom Mobile:

1. Open your image in Lightroom Mobile
2. Tap the Detail Panel
3. Use Noise Reduction AI or manually adjust Luminance & Detail
4. Fine-tune with Texture & Clarity
5. Export your final image

📌 Shortcut Tip: Press the Before/After icon to see how noise reduction affects the image in real time.
