As a developer for Photoshop (and now Aperture) I rarely spend time in other host graphics apps. There are other purchasable ones, like the Corel Painter Suite, but they generally don’t publish a good API that plugin developers like Digital Anarchy (that’s us) can hook into. There are also a bunch of free image editing apps. For our customer model, they simply fall short of what Photoshop can do and none are widespread enough for us to support. Which makes sense since these free apps are not trying to be Photoshop, just act as an alternative for folks who aren’t doing graphics for a living and don’t want to invest money into graphic manipulation. Having said that, I occasionally run into a summary list of free Photoshop alternatives. Thought it would be interesting to post a list that I found on Downloadsquad.com through a friend’s blog, pirandello.wordpress.com.
