How to Edit True Bayer RAW Photos in Lightroom

Editing a true Bayer RAW file is different from editing a standard JPEG or an Apple ProRAW file. Because the file contains pure, unadulterated sensor data without computational enhancements, it requires a different approach in Adobe Lightroom.

Step 1: The Starting Point

When you open a Bayer RAW DNG in Lightroom, it will likely look flat, slightly noisy, and perhaps a bit dark. This is normal. It means you have the maximum amount of data to work with.

Step 2: Exposure and Contrast

Unlike ProRAW, which already has Smart HDR applied, you need to manually establish the contrast curve.

1. Adjust the Exposure slider to set the overall brightness.
2. Add Contrast (usually +10 to +30) to bring the image to life.
3. Carefully lower the Highlights to recover sky details and raise the Shadows to reveal darker areas.

Step 3: Managing Noise (The Organic Way)

Bayer RAW files retain the natural noise of the iPhone sensor. Many photographers love this film-like grain. If you prefer a cleaner look:

1. Go to the Detail panel.
2. Apply Color Noise Reduction (usually around 10-20) to remove color blotches in the shadows.
3. Apply a small amount of Luminance Noise Reduction (10-15), but be careful not to overdo it—aggressive noise reduction creates the "plastic" look we are trying to avoid.

Step 4: Color Grading

This is where Bayer RAW shines. Because the colors haven't been pre-baked by Apple's algorithms, they respond beautifully to grading.

1. Adjust the White Balance using the Temp and Tint sliders. You have complete flexibility here because the white balance wasn't locked in at the time of capture.
2. Use the Color Mix tool to isolate and enhance specific colors (e.g., deepening the blues in the sky, or warming up skin tones).
3. Apply a cinematic Color Grade by adding warmth to the highlights and a cool tone to the shadows (Teal & Orange).
