Image processing software, that can modify and manipulate common photograph formats in a number of interesting ways with plugins and advanced controls.

ImageJ is an image editor made in Java, which allows it to run on any operating system that supports the platform. As it is free software, its user community is large and often shares various improvements made to the program. Its main highlight is the creation of macros, as this makes it possible to automate the execution of several tasks with the press of just one button.

If you use several computers with different operating systems, having a portable image editor capable of working on all of them is very important. ImageJ is a good choice in that respect, because it presents this functionality and has several editing resources as well as create macros.

ImageJ's interface isn't exactly intuitive for those who don't know English or aren't used to programs that require extensive use of the upper menus. Having said that, it is worth mentioning the general options found in these menus.

The first impression of ImageJ is what it lasts: it is not a very friendly program. This happens not only because of its look, but also because of its interface. It is extremely simple and has very few buttons to help the user (despite having several keyboard shortcuts).

Given the fact that it has open source and several resources for developers, ImageJ is a full plate for anyone who knows how to change it satisfactorily. After all, the possibility of creating macros is interesting to automate the execution of several tasks with the press of just one key. In addition, another nice feature for developers is that it runs in Java, which allows running it on any OS.
