It took a while to adjust to Gimp, after having been first trained in Adobe Photoshop. Once you stop treating it as a Photoshop replacement/free-libre open source copy of the Adobe image editor, you soon realise that it stands up as a fantastic editor regardless. I've been using it for nearly a decade now, and loving every minute.
"GIMP is an amazing image editing software package similar to Adobe Photoshop, but licensed as free and open source. The latest version of GIMP (2.8) has been downloaded over 6.5 Million times in just two months, so this is a huge community of skilled & dedicated users.
GIMP Magazine features the amazing works created from this world wide community. Photography, digital arts, graphic arts, design, tips & tricks, step by step tutorials, master classes, help desk questions, book and product reviews and so much more are showcased and explored in this quarterly publication. This publication is available for free and is licensed Creative Commons CC-AT-SA 2.5."http://gimpmagazine.org/
