At the moment I am wondering if Gimp is good replacement for Photoshop.
I have now played around with gimp but I find that user interface still needs some improvement. But on the other side I most probably need some time to adopt.
I'm using Gimp, for the money - $0, I get exactly what I want and need, but yes it takes a bit of getting used to, especially if you're coming from the Photoshop world. They are both great, the free factor does it for me.
I tried to getting used of new UI in Gimp but somehow Photoshop still beats it with better tools and UI too. But I will give Gimp more chances and I just hope that Photoshop will someday get real alternative.
But for sure ... I think alternative is web based.
