An acronym for Optical Multi-Channel Analyzer, OMA for Mac acts as a photometric image processing and display software. Though this app's framework is rather old, its main features can still come in handy.
Feature-rich: OMA for Mac offers a wide range of features including camera and digital I/O control, 2D vector field processing, macro scriptability, basic and complex image processing, Particle Image Velocimetry (PIV) processing routines, and the ability to display photometric images with custom color maps, all of which work as intended.
Plenty of macros: The official Web site of the software features many free macros and sample OMA images created by other users.
GNU Public License: OMA for Mac's full source code is available for download. However, you need to register if you plan to modify it.
Outdated programming language: The most recent version (version 3.0) of the app was built using Carbon framework, a relatively outdated language especially in the context of running applications on Mac OS. A new version is in the works, though. It will be Cocoa-based and will employ C++ image class.
No 64-bit mode: The upcoming version of this software will run in 64-bit mode and is expected to offer better performance.
While OMA for Mac features a photometric image processing and display software that can still be useful to some, this app feels outdated, overall. It needs to be updated to properly compete with other similar applications. So wait until the new version.
