How to Scan Old Photos for Digital Restoration

Why Scanning Quality Matters

AI photo restoration is only as good as the input it receives. A high-quality scan captures the actual scratches, fading, and grain of the original print. A poor scan adds its own artifacts — compression noise, uneven lighting, perspective distortion — and the AI can't distinguish original damage from scanning error.

Spending ten extra minutes on a proper scan can be the difference between a mediocre restoration and one that makes your family emotional.

Flatbed Scanner vs. Phone Camera

You have two main options for digitizing old photos, and the difference in quality is significant.

Flatbed Scanners

A flatbed scanner is the gold standard. Even an inexpensive consumer flatbed from Epson or Canon will outperform a phone camera for photo scanning. Here's why:

  • Uniform lighting — the scanner's built-in light bar moves evenly across the photo, eliminating shadows and hot spots.
  • Precise resolution control — you set the exact DPI, and the scanner delivers consistent pixel density edge to edge.
  • No perspective distortion — the photo lies flat on glass, so there's no warping or keystoning.
  • Consistent color — the sensor reads color values directly without being affected by ambient room lighting.

If you don't own one, check your local library. Many public libraries offer free scanning stations.

Phone Camera

Sometimes a flatbed isn't available, and your phone is all you have. Modern phone cameras are surprisingly capable, but they introduce challenges that you need to manage carefully. We'll cover phone scanning tips in detail below.

Recommended DPI Settings

DPI (dots per inch) determines how many pixels your scan captures per inch of the original photo. Higher DPI means more detail, but also larger file sizes.

Standard Prints (4x6, 5x7, 8x10)

300 DPI is the minimum. This gives you enough resolution for AI restoration and reprinting at original size. For enlargements, scan at 600 DPI.

Small Originals (wallet photos, ID photos, passport photos)

Small photos need 600 DPI or higher. At 300 DPI, a wallet-sized photo captures so few pixels that the AI has very little to work with.

Large Prints (11x14 and above)

300 DPI is sufficient. The physical size means you're already capturing millions of pixels.

When in Doubt

Scan at 600 DPI. Storage is cheap, and you can always downsample later.

File Format: PNG and TIFF Over JPEG

This matters more than most people realize. File format affects every restoration you do with that scan.

  • PNG — lossless compression. Every pixel is preserved exactly as scanned. This is the best default choice for most people.
  • TIFF — also lossless, and supports higher bit depths. Best for archival purposes, but files are larger and some web tools don't accept them.
  • JPEG — lossy compression. Every time you save a JPEG, it throws away detail to reduce file size. Those compression artifacts become permanent noise that the AI has to work around.

Always scan to PNG or TIFF. You can convert to JPEG later for sharing, but start lossless.

Handling Fragile Photos

Old photos can be brittle, curled, or stuck to album pages. Handle them with care:

  • Wash your hands or wear clean cotton gloves. Oils from your skin can stain the emulsion.
  • Don't force curled photos flat. Place curled photos face-down on the scanner with a soft weight on top, but don't press hard enough to crack the print.
  • Never peel stuck photos apart. Scan them as-is rather than risking a tear. You can crop the restoration later.

Scanning Negatives and Slides

If you have the original negatives or 35mm slides, these are often better sources than prints. Negatives contain more detail because the print itself introduced grain and resolution loss. You'll need a scanner with a transparency adapter — scan at 2400-4800 DPI for 35mm film to capture the full detail potential.

Phone Scanning Tips

If a flatbed isn't available, these tips will close the quality gap:

  • Use diffused natural light near a window. Avoid direct sunlight and flash — both create glare.
  • Hold the phone directly above the photo, parallel to the surface. Any angle introduces perspective distortion. Use a stack of books or a phone mount for stability.
  • Use the highest resolution available. Shoot in RAW format if your phone supports it.
  • Turn off flash — it creates a bright hot spot in the center.
  • Try a dedicated scanning app like Google PhotoScan or Microsoft Lens. They capture multiple exposures to remove glare, auto-crop, and correct perspective.

Organizing Your Scanned Files

Before scanning a shoebox of photos, set up a simple system. Create folders by decade or event, and name files descriptively: grandma-rosa-wedding-1962-001.png beats IMG_4829.png. Keep a simple text file noting who's in each photo and the approximate date.

Next Steps: Restore with PhotoFlip

Once your photos are scanned properly, head to the restore tool to begin restoration. A high-quality scan paired with AI restoration can produce results that look better than the original print did on the day it was developed.

After restoring, take your photos further:

  • Face restore — sharpen blurry or damaged faces, especially in group photos where individual faces are small
  • Colorize — add historically accurate color to black-and-white photos from any era
  • Upscale — increase resolution up to 4x so small scans become print-ready images

Upload your scan, and you'll see the restored version in seconds. The better your scan, the more the AI can do.
