Digital Art can generally be defined as art that has been created through digital means – more specifically, where the end result is a digital file that can be downloaded and viewed.
I typically use digital art as a means to an end, although I do make full digital pieces, too.
A good use for digital art in my work is as a way to quickly sketch or visualise colours that I will be using on one of my canvases; the use of 3D digital art also allows me to portray the composition of imagined scenes with more accuracy.
