Photo Scanner Buying Guide

Scanning photographs is a different job from scanning documents. The specs that matter, and the mistakes to avoid, are not the same — using a document scanner for treasured prints usually disappoints.

Why Photos Need Different Specs

Documents scan fine at 300 DPI; photos need far more. For prints, 600 DPI is a practical minimum and 1200 DPI lets you reprint larger. For negatives and slides, you need 2400–4800 DPI because you're enlarging a tiny original. Color depth (48-bit) and dynamic range also matter far more than for text.

Flatbed vs Dedicated Photo Scanner

A good flatbed scans prints well and, with a transparency unit, can handle film. Dedicated photo/film scanners produce higher quality for negatives and slides but cost more and are slower. For a box of old prints, a flatbed with an automatic feeder or a fast photo scanner saves hours.

Film, Negatives and Slides

To scan negatives or slides you need a scanner with a transparency adapter (backlight) — a normal flatbed that only lights from below cannot do film properly. Check the film formats supported (35mm, medium format) before buying.

Restoration Features

Look for dust and scratch removal (hardware-based, like Digital ICE, works better than software), color restoration for faded prints, and batch scanning to get through large collections.

FAQ

What resolution do I need to scan old photos?

For prints, 600 DPI is a practical minimum and 1200 DPI allows larger reprints. For negatives and slides you need 2400–4800 DPI because you're enlarging a very small original.

Can a regular document scanner scan negatives?

No. Negatives and slides require a scanner with a transparency adapter (a backlight). A standard flatbed that only lights from below cannot scan film properly — check for film support before buying.

What's the difference between a photo scanner and a document scanner?

Photo scanners offer much higher resolution, better color depth and dynamic range, and often film support and dust/scratch removal. Document scanners prioritize speed and OCR at lower resolution.
