A small studio with one focus: your images

Prismatic Software makes programs that each solve one clear problem: process a stack of photos, find duplicates, build a mosaic. Since 1999, and never with ads.

No ads

No toolbars, banners, data collectors or “helpers” in the installer.

Tiny footprint

Installers range from a few dozen kilobytes to a few megabytes.

Nothing without asking

Our programs show you results; what happens to your files is your call.

Clear documentation

Manuals and articles on how processing, comparison and mosaics actually work.

How it all came together

From the first mosaic experiments to a toolkit for an entire photo archive.
