Ambereh is a basic drawing application with the advantage of having the possibility of sharing your work while chatting with your co-workers and applying changes that everybody can see.
It's surely not Photoshop, nor even a bad copy of it, but that's not its purpose. It is not a professional photo editor but a tool to share ideas on logos, for example, or simply a kind of dashboard for creative having to work from different locations. Define a local port and connect to a computer in the relative menu at the top of the program's page and start to work on a drawing with other people.
The application can only work with bitmaps and this is really a big limitation considering that this format is not so widely used anymore. The features are just the basic ones you can find in all the other drawing editors such as anti-aliased brush, custom bitmap brushes, opacity control, smudge and blur. Furthermore this program is free and open source.
Ambreh's simplicity makes it an interesting tool for brain-storming sessions with your colleagues as you can make changes to an image that everybody can see live and chat at the same time.
