Like most artists, I like to take a sketchbook with me everywhere. My hubby thoughtfully bought me a Nintendo art program that has been wonderful!!! My little handheld Nintendo has a camera attached to it, and with the program, I just snap a photo, and it becomes my reference. It has a graph that can be placed over the photo to help with drawing, and the program has a pencil and paint brushes. You can even add 'water' to the paint to make washes and thicken the paint for heavy brushstrokes. This is my painting of a raccoon that I photographed in my backyard. While I cannot make a 'hard copy' of my painting, I get lots of practice in when I am traveling, and I can try out new color choices and work on my drawing skills. I am constantly amazed by the technology being produced daily in this world!!!
