How to digitise film negatives with your phone
You don’t need a film scanner to rescue old family negatives. A phone, an even light source and a free converter will get you excellent results in an afternoon.
What you need
- An even, bright light source. A light box or LED tracing pad is ideal. A tablet or laptop showing a blank white screen at full brightness works well too.
- A way to hold the film flat. A negative holder, two strips of card, or a piece of anti-glare picture-frame glass laid on top.
- Your phone, ideally on a small tripod or propped on books so it sits parallel to the film.
- Cotton gloves and a blower brush to keep fingerprints and dust off the film.
Step 1: Set up in a dark room
Turn off overhead lights so they don’t reflect off the film. Mask the light source around the negative with black card. Stray light reduces contrast and makes colours washed out.
Step 2: Position the phone
Hold the phone exactly parallel to the film so the frame isn’t distorted. Fill as much of the screen as you can with one frame, but leave a sliver of the clear film border visible. You’ll use it later to remove the orange mask accurately. Avoid using digital zoom; move the phone closer instead, or use the 2× lens if your phone has one.
Step 3: Camera settings
- Turn the flash off and disable HDR, “scene optimiser” and beauty filters. They fight against the conversion.
- Tap to focus on the film grain, then lock exposure (press and hold on most phones). The film border should look bright but not pure white.
- If your phone has a Pro or RAW mode, use it and keep the ISO low.
Step 4: Convert to a positive
Open the negative to photo converter, drop in your photo and choose Colour or B&W. Then:
- Click Pick film border and click the clear orange edge of the film. This gives the converter the exact colour of the film base.
- Click Pick neutral grey and click something that should be neutral, like a white wall, grey pavement or cloud.
- Fine-tune with Brightness, Midtones and Warmth, then download at full resolution.
Troubleshooting
| Problem | Fix |
|---|---|
| Photo looks blue or cyan | Use “Pick film border” on the clear edge, then add a little Warmth. |
| Flat, low contrast | Block stray light around the film; increase Contrast slightly. |
| Rainbow patterns (Newton rings) | The film is touching glass. Use anti-glare glass or a holder that keeps a gap. |
| Dust spots | Blow the film clean before shooting; clean the light box surface. |
| Image is mirrored | Use the Flip button. You photographed the emulsion side. |
Finishing touches
Scans straight from a phone can be large. Use the image compressor before emailing them to family, and remove the metadata if you’re sharing them publicly.
