This guide focuses on maintaining the integrity of archival assets for high-resolution output and historical preservation.

• Resolution & Format: Scan at a minimum of 600 DPI (1200 DPI preferred for small snapshots) and save as uncompressed TIFF files to avoid artifacting.   

• Color Profile: Capture in 24-bit RGB even for black-and-white photos to preserve the full tonal range and subtle chemical shifts in the original paper.   

• Physical Alignment: Ensure the scan bed is cleaned with a microfiber cloth; align the image to the grid to avoid digital rotation, which can degrade pixel clarity.

• Bit Depth: If your hardware allows, scan at 16-bit to provide the maximum “headroom” for colorization and contrast recovery.   

• Handling: Use archival gloves when handling original prints to prevent oil transfer; do not use “Auto-Fix” or “Dust Removal” scanner software, as these algorithms often blur fine historical details.

Scanning Concepts

• The “600 DPI” Rule: When you open your scanner settings, look for “Resolution” or “DPI.” Set it to 600. This ensures your photo stays clear even if we need to print it at a larger size.   

• Disable “Auto-Enhance": Many scanners try to “fix” the photo automatically. Please turn these features off; they often hide the very details we need to restore.   

• Glass & Dust: Wipe your scanner glass gently before you start.  A tiny speck of dust on the glass can look like a major blemish on a person’s face once the photo is enlarged.   

• No Scanner? Use Your Phone: If you don't have a scanner, you can take a photo of the photo.

  • Lighting: Place the photo near a window for natural light, but avoid direct sunlight or “hot spots” from lamps.

  • Angle: Hold the phone directly above the photo—not at an angle—to avoid distorting the shape of the image.

  • Flash: Keep your flash OFF to prevent glare and reflections.

• Sending the File: When emailing or uploading, always choose the “Original Size” or “Actual Size.” Sending a “Small” or “Medium” version shrinks the file and loses the quality we need to work our magic.
