The moon was full and there were no clouds, so I decided to take a photo. It is very simple. Put your camera into manual mode and set the ISO to 100, aperture to f16, and shutter speed to 1/100 of a second. I took five shots varying the exposure about 1 stop at a time, but they were all overexposed. I went back and took some more with the shutter speed of 1/1000 of a second, which is 10 times faster. They were still overexposed. The problem was that my very smart camera decided that the shot was underexposed and increased the ISO to 6400. I had to check the manual to find out how to turn off that feature. In the end it worked just as it was supposed to.
