Kestrel GX (Version: 1.2.1 as of this post) is an attractive photo editor that also helps organize photos into one or more databases. It supports many image formats including JPG and others but also Photoshop’s PSD format and RAW formats. Photos can be arranged into PDF albums to share easily with others. The usual edits like resize, rotate, flip, convert, remove red eye, saturation, rename and others are available but Kestrel GX lets you choose an external application (File —> Open In External Editor) for editing images.
Kestrel GX is perhaps mostly useful as a photo organizer. Not only it can be used to edit and search EXIF, IPTC and even GPS data associated with images but it can also be used divide images by rating, category and keywords and store them into their own database(s) managed by the program to view and also search for later.
Kestrel GX has print capability that includes a few ways or templates to print and also a slideshow (View —> Slideshow) with 163 transition effects. To top it all of it does both image and text watermarks (File —> Watermark Images) too. Kestrel GX is one of the most complete photo applications out there and is free for personal and educational use only. It requires Windows XP and up.
