There are certain processes I have come to follow when creating a digital painting. First and foremost for me is to draw the individual elements. At one time I would have tried to set them on the same piece of paper and worked with them where they were, not allowing myself the freedom to rethink the layout of the final image. Because I struggled so much to find time to draw or paint, I had a bad habit of giving up on ideas if they did not work out right away. I am now thankful for Gimp allowing me to correct parts of an image without affecting the larger painting, much as word-processor allows a two finger typist to complete a large number of short stories. Another thought on drawing the initial images is that mine are always drawn freehand. Even if I struggle to get the image right, I still use my drawing. It is an integrity issue for me.
Once I have the drawings done, I scan them into the computer as a jpegs. As I have gotten more comfortable using Gimp, I have learned to keep the elements separate until I am ready to place them into the final picture. I take each image and make the drawings sit on a transparent background. Then I create a transparent layer above or below the drawing layer, depending on where I think I will have trouble working on the image. This is where I will paint the actual artwork. In addition, I will add another layer below these, which will become a temporary background that can be changed as needed to better see the painting I am working on.
Next comes the under painting. This is where I just put the basic colors on the image such as skin tone, hair color, or fabric color. I don’t work on details at this point; I just want to completely fill in the areas I intend to work on with their basic colors. After the under painting is done, I will begin the true creation of the individual pieces. The detail work is the longest part of any painting for me.
When I have the parts done as much as I can or want, I will copy them into a larger final image as different layers. I like to keep them in layers until the very end in case I need to adjust their position without affecting anything I have done on the background piece I placed them on. However, there comes a point in most images where I have to combine the layers into one to help with connecting them into one coherent picture. My current habit is to hold off as long as I can. At this point it is all about making adjustments around the parts to make them fit the larger image. Then I tinker with the painting until I am done.
