Choosing software for lightening shadows depends on how much control you want versus how much "magic" you expect.

If you want a "one-click" solution where Artificial Intelligence (AI) analyzes the 3D space of your photo to brighten dark areas naturally, Luminar Neo is widely considered the best option. If you prefer professional control to recover details manually, Adobe Lightroom remains the industry standard.

Here is the breakdown of the best software for automatically lightening shadows.

1. Best for "One-Click" AI Automation

These tools use AI to "understand" the photo (e.g., distinguishing a person from a background) and relight it intelligently, rather than just brightening every dark pixel.

• Luminar Neo (Skylum)

  • The "Magic" Feature: Relight AI. This tool creates a 3D map of your image, allowing you to brighten the foreground (usually where the subject is) separately from the background. It creates a very natural look without the "halo" effect common in older software.

  • Best For: Users who want to fix a backlit photo (where the subject is dark because the sun is behind them) in seconds without learning complex editing.

• Topaz Photo AI

  • The "Magic" Feature: Adjust Lighting. This software is famous for sharpening and noise reduction, but its newer "Adjust Lighting" module automatically detects underexposed areas and balances the tones.

  • Best For: Fixing low-quality or blurry images that are also too dark. It fixes shadows, noise, and sharpness all at once.

2. Best Professional Automatic Tools

These are pro-grade tools that offer powerful automatic starting points but allow for deep manual refinement.

• DxO PhotoLab

  • The "Magic" Feature: Smart Lighting. This is arguably the best non-AI "automatic" algorithm. It analyzes the dynamic range (the difference between lights and darks) and automatically pulls detail out of the deep shadows while protecting the highlights.

  • Best For: Photographers who shoot in RAW format and want the highest possible image quality and detail recovery.

• Adobe Lightroom (Classic or CC)

  • The "Magic" Feature: "Auto" Button & Shadows Slider. While known for manual sliders, Lightroom’s "Auto" button (in the Tone panel) is surprisingly excellent at setting a balanced exposure.

  • Best For: Users who want a reliable standard. If the "Auto" button isn't enough, you can simply drag the "Shadows" slider to the right to recover details instantly.

3. Best Free & Mobile Options

You don't always need to pay for expensive desktop software.

• Google Photos (Mobile/Web)

  • How to use: Open a photo > Edit > Enhance (magic wand icon). If that's not enough, go to Adjust > Shadows and slide it up. It is incredibly effective for a free tool.

• Snapseed (Mobile - iOS/Android)

  • How to use: Go to Tools > Tune Image > Shadows. It allows you to selectively brighten dark areas with a simple swipe.

• Darktable (Free Desktop)

  • Note: This is a free, open-source alternative to Lightroom. It is very powerful but has a steep learning curve. It has a "Shadows and Highlights" module, but it is less "automatic" than the AI tools above.

Summary Comparison Table

Important Distinction: "Lighten" vs. "Remove"

• If you mean "Brighten a dark photo": Use the tools above. They recover details hidden in darkness (underexposure).

• If you mean "Remove a cast shadow": (e.g., a shadow of a tree branch across a face), you need Object Removal tools.

  • Luminar Neo represents this well with "GenErase" (Generative AI).

  • Photoshop is the king here with "Generative Fill."

  • TouchRetouch is a great affordable app specifically for removing these kinds of unwanted marks.

Recommendation: If you are willing to spend a little money for the easiest result, Luminar Neo is currently the leader for "automatic" relighting. If you want a free quick fix, try Google Photos first—it's likely already on your phone.
