Correcting Lighting and Exposure
Fix underexposed, overexposed, and backlit photos with AI-powered lighting adjustments that recover lost detail.

- 1Diagnose common lighting problems by reading a histogram and identifying clipped highlights or shadows
- 2Use AI exposure correction to recover detail in shadows and highlights simultaneously
- 3Apply local lighting adjustments to fix uneven illumination across different areas of the frame
Fixing underexposed and overexposed images
Lighting problems are the most common issue in casual photography. Backlit subjects appear as dark silhouettes, indoor shots without flash come out murky and underexposed, and mixed lighting creates images with some areas too bright and others too dark. The histogram is your diagnostic tool: a graph pushed entirely to the left indicates underexposure, pushed to the right means overexposure, and gaps in the middle suggest low contrast. Understanding the histogram helps you identify the problem before choosing a fix.
Dynamic range recovery techniques
AI exposure correction goes beyond simple brightness adjustment by analyzing different regions of the image independently. When you boost exposure on an underexposed portrait, traditional tools brighten everything equally, blowing out the sky behind the subject. AI correction recognizes the subject separately from the background and applies different exposure adjustments to each zone. It can pull shadow detail out of a dark foreground while keeping a bright window background properly exposed, effectively simulating the HDR technique that professional photographers use.
Contrast adjustments for different subjects
For unevenly lit photos, such as a room with bright windows on one side and dark corners on the other, use local lighting adjustments. The AI identifies distinct lighting zones and lets you balance them so the entire scene appears naturally lit. Increase shadow recovery gradually rather than applying maximum correction, as pushing too hard introduces noise in the darkest areas. A good rule of thumb is to recover detail until you can see texture in the shadows, then stop before the image starts looking flat or noisy.
Key Takeaways
- ✓Read the histogram to diagnose whether a photo is underexposed, overexposed, or low contrast
- ✓AI exposure correction adjusts different image regions independently, similar to HDR processing
- ✓Recover shadow detail gradually and stop when texture is visible to avoid introducing noise
