Others call this creating artwork from Chaos. Every artist that uses this software involves themselves in finding shapes and form in the chaos they create in Alchemy. It's a continuous process of putting shapes on top of each other until a visual inspiration and interpretation pops up from the chaos that is created.
Watch a sample by David Revoy how alchemy was used to create a beautiful digital artwork using Alchemy to start of the creative process.
As you have watched on the video above, David Revoy used free downloadable softwares for the whole art and design process. These are Alchemy, GIMP, and MyPaint. This just shows you that you don't need expensive software to make awesome artworks just like what you've seen above.
If you are interested in trying out Alchemy, check out their website to download the software. It's free!
