I find that painting something - usually scenery - can get those creative juices flowing.
I paint from many sources, and as I know I'm never going to be a "painter" - not being good enough for that - I'm not too precious about it. I paint from life, in other words I go out and pick a scene and paint it.
I also paint from... well, imagination. I may see a scene on a calendar that takes my fancy. Or I may find that one of the pictures I took with my digital camera is way too dull, but after jazzing it up with one of the "Paint" or "Photo" bits of software, I end up with something that could be fun to paint. Why not? It's not hurting anybody, and I enjoy it. FB
