Artist Reply: Hello Warren, Your guess is correct. Unfortunately I don't know how to take advantage of the many features on my camera, but I will keep trying to figure them out. Ideally with a subject like this one I would use a tripod and open the apeture more and slow down the shutter speed due to the lack of light and use a remote release to eliminate shake. Fortunately I have a lens with vibration reduction and a camera with pretty a good auto focus mode. All I have to do is be there and push the button. I think this one was a little under exposed but I'm not expecting to sell any for their quality but maybe a few for their uniqueness and maybe someone will buy some to help me buy some photo lessons. Thanks for your comments and have a great day, George
