So for all the artists of whom I am watching and for those whom I am not, what materials do you use to make your art, how exactly do you get the image on the computer before submitting it? I now how to submit art but I've always wondered how has artists been able to put their work on the computer without taking a picture of it or scanning with a printer if the light could damage the work? Example: a painting of acrylic oil or a pencil drawing.

Some really helpful answers would be great. Thank you.
