I often take Work In Progress (WIP) photos as I paint. I do this mostly because it helps me to see how a painting is progressing and isolate things that need attention early. Viewing my work in the photo allows me to remove myself from it some what and view it through fresh eyes.
Here is a series of photos as my Christmas Faerie painting progresses. The finished painting is 8×10 inches and was painted with watercolors on Hot Press paper.
