As this was my last visit of the year, I decided to linger a bit longer rather than the usual go in get some record shots of any changes and out again. I also wanted to see how my new Sigma 16mm/f1.4 DC DN/C lens handled the rubbish lighting at the museum.  There are at least four different types of light bulbs used and if you correct the white balance on one you get a weird colour cast on another. As the camera and lens do not have image stabilisiation built in, I started out by using the rule of thumb of the shutter speed equaling the the length of the lens. In this case 16mm on a crop sensor equals 24mm so I started the shutter speed at 1/20th second and gradually reduced it down as confidence grew. I left the IOS on AUTO with the maximum set at 6400.  In the order taken.
