Differences between versions. Which is right for you?

Imatest is available in two versions.

  • Imatest Studio, with everything individual photographers need to test their cameras, lenses, and printers.
    Studio is only available to individual photographers.
  • Imatest Master, the full-featured industrial-strength version for engineers and scientists who develop and evaluate imaging systems.
