VERDICT

Should I use ImageJ?

Open-source, Java-based scientific image analysis platform - imagej.net

Worth it. Adopt ImageJ if you do scientific or microscopy image analysis and can tolerate a learning curve. Skip it if you need vendor support, polish, or general-purpose photo editing.

Confidence

Medium. Based on 20+ public sources including G2 reviews, Reddit threads, security forums, and official documentation. Several snippets were truncated, limiting verbatim quote depth.
