Digital art is an art form in which traditional painting techniques such as watercolor, oils, etc. are applied using digital tools by means of a computer, a graphics tablet and stylus. I use Wacom tablet for my digital artworks. It is great tool to experiment with using either Photoshop or Artrage studio the two I am familiar with.
Very recently I have started doing digital art on the photos which I take. I am enjoying using my mobile to add digital enhancements to the photograph (water, reflections, birds, rocks, trees, plants etc.)
