Open source, has one of the most interesting features of a large quantity of brushes (brush), with additional storage that can be downloaded separately.
The graphical interface is not equal to that of its competitors-especially-Phierha, but if nothing else is very simple (the graphics of different brushes, however, is really nice).
MyPaint for a tutorial is also available in English, which helps to understand how it works (http://mypaint.intilinux.com/?page_id=3).
At the time of the rescue plan is not protected: if you draw and you accidentally close the window, will be released without asking to save (be careful not to accidentally lose a few hours of work). There are other better things: for example, I could not merge the layers (perhaps before adding more).
Good program, with great potential, but it is still a bit street to be equal to the best.
It’s another program of the highest quality, the kind of Paint.net, which can be used free of charge even for commercial purposes. Fast, light and intuitive, so that you can use instantly without reading a line of instructions, with great user interface but also powerful. It almost on the level of Paint.net, or almost (for those looking for a light program and could also be more immediate.)
Unfortunately, there are categories in which to find high quality free software is very difficult and others-like this-where applications are a lot of value.
Although it was only a demo version is fully functional (maybe certain programs such as this were called free demo version).
Of all the programs to create landscapes that I know, Autostitch is the easiest and most automatic (as well as Microsoft ICE is actually very easy), since he has very few options, and that is not no need to configure: you just put pictures in a folder, click Start and the program will automatically create a panoramic image in JPEG format.
The results are quite good. It’s true that, if you get a little test-Hugin you get a better result, but the simplicity of AutoStitch is difficult to match.
