Tree of Life was created in Adobe Photoshop 5.
I pulled from my experience of painting and working in the darkroom. By creating the entire art piece with just three Photoshop tools. Paint Brush, Dodge, and Burn Tools.
By focusing on tools that I understood (in the real world), I quickly grasped the abilities and limitations of working with digital tools. Since then, I have become a Photoshop Master - with a vast knowledge on all of the tools.
