How to scan color negatives on a flatbed scanner

Negatives are often the only surviving record of photos that were never printed — or printed once and lost. Scanning them is a little more involved than scanning prints, but it can recover images you've never actually seen. Here's how.

Why negatives look orange

Hold a color negative up to the light and it looks orange and inverted. The inversion is expected — a negative reverses light and dark, and every color becomes its opposite. The orange cast is the film base: a mask built into color negative film that has to be removed when you turn the negative back into a positive. Get the inversion and the base removal right and natural color comes back; skip the base and everything looks tinted.

The steps

1. Use a scanner that backlights film

   Prints are scanned by reflected light, but negatives are transparent and must be lit through. You need a flatbed with a transparency unit (a light in the lid) or a dedicated film scanner. A standard flatbed without one can't properly scan film.

2. Handle and place the film clean

   Hold negatives by the edges and dust them gently — scratches and specks are magnified at this scale. Lay the strip flat, emulsion-side down, ideally in a film holder so it stays level and in focus.

3. Scan at high resolution

   A negative frame is small and will be enlarged a lot, so scan far higher than you would a print — 1800 to 3200 DPI is a good range. Save as TIFF or high-quality JPEG.

4. Invert the orange film base

   Turn the negative into a positive and neutralize that orange mask so the colors read naturally. CapCrop detects the orange film base and inverts toward natural color for you, so you don't have to hand-tune curves frame by frame.
