For the last couple of years Aviary has been steadily rolling out a slew of web-based image editing tools. With only a handful of exceptions these tools have been completely free to use. Ten days ago Aviary announced a change to that policy and is now giving free, unlimited, access to all of their editing tools. These tools include a vector editor, color editor, image editor, effects editor, image markup tools, screen capture tools, and sound recording and mixing tools. Embedded below is a fast-paced overview of Aviary's image editor.
Applications for Education
Aviary probably won't replace Photoshop in commercial settings anytime soon, but for schools Aviary could be a great way to introduce students to the principles of image editing, markup, and vector editing. Aviary's sound recording and mixing tool that they offer is an excellent free alternative to Garage Band that I've used in my classroom.
