DPI stands for “dots per inch.”

It’s a way of measuring how much detail appears in a scanned or printed image. In general, higher DPI means a sharper and more detailed photo.

Why DPI Matters

DPI can affect:

• Print quality
• Image sharpness
• Zooming capability
• Photo restoration flexibility

Higher DPI can help preserve more detail when digitizing old family photos, especially if you plan to print, enlarge, or restore them later.

What DPI Can You Get With Photomyne?

With Photomyne, scan quality depends on several factors, including your phone camera, lighting conditions, and how the photo is captured.

For the highest-quality results, it’s best to scan one printed photo at a time and let the image fill most of the camera frame.

Under good conditions, Photomyne can reach roughly 400–800 DPI equivalent quality when scanning individual printed photos.

Scanning multiple photos at once is much faster and great for large collections, though each image will contain slightly less detail.

Does Higher DPI Always Mean Better Quality?

Not always.

Many old printed photos were originally low resolution, so extremely high DPI may not reveal significantly more detail.

The condition and quality of the original print still play a major role in the final result.

Final Takeaway

DPI measures how much visual detail is captured in a scan.

With Photomyne, families can create high-quality digital photo archives directly from a smartphone, with enough resolution for sharing, photo books, digital preservation, and everyday printing.
