Tips

Choosing your base image

Your base photo is the large image the mosaic resembles from a distance. Every tile is pulled from your library, so the base sets the mood — not the individual snapshots. The best bases share a few traits:

• Low detail

  Avoid busy faces, fine text, or intricate textures. When the mosaic is built from hundreds of small photos, sharp local detail gets replaced by tiles — simple shapes and broad areas survive that process much better.

• Symbolic theme

  Pick an image that stands for the whole collection at a glance — a landmark from the trip, the graduate in cap and gown, the couple at the altar. It should summarize the story of your library, not document every moment in one frame.

• Recognizable silhouette

  Choose a subject with a clear outline — a profile, monument, tree line, or bold object on sky. Even when tiles cover the surface, viewers should still read the shape from across the room.

• Interesting colors

  Strong, varied color in the base gives the matcher room to place your library’s colorful shots. A flat or monochrome base can make the mosaic feel muddy; a base with distinct color regions helps every photo find a home.

• Interesting patterns

  Repeating lines, gradients, or graphic contrast make the poster eye-catching up close while the underlying theme still reads from afar — structure up close, meaning at a distance.
