Convert iPhone ProRaw film negative scans to positives online.
Negative Converter can open iPhone ProRaw DNG files from camera-scanned film and convert them to positive images locally in the browser. It is free, private, and works without a Lightroom or Photoshop workflow.
Can an iPhone scan film negatives?
Yes. An iPhone that supports ProRaw can photograph a backlit 35mm or medium format negative as a DNG file. Negative Converter then inverts the negative, corrects the mask, and exports a positive image without sending the photo to a server.
The scan quality depends on even illumination, focus, film flatness, and avoiding reflections. A copy stand, stable holder, clean light source, and manual exposure help more than any software correction later.
Recommended capture setup
- Use a clean, even light source behind the negative.
- Keep the film flat and parallel to the phone camera.
- Use ProRaw DNG if available to preserve tonal range.
- Expose so highlights are not clipped in the film base.
- Crop out the holder and keep the unexposed border if you want better mask sampling.
ProRaw conversion steps
- Capture the negative as an iPhone ProRaw DNG.
- Open Negative Converter and select the DNG file.
- Crop to the frame and use Auto Frame if the border is visible.
- Select Color Negative, B&W Negative, or Positive mode.
- For color negative film, sample the orange mask from the border or use auto detection.
- Use gray point sampling and color controls to finish the image.
Why use a browser converter for ProRaw?
Phone film scans are often quick tests or personal archive images. A browser converter lets you review and finish them without creating a full desktop editing session. Because Negative Converter processes locally, the ProRaw file stays on the device.
