During the next full moon get out your tripod . . .
A full moon offers a surprising amount of light. All you need is a subject that you want illuminated, a tripod, and the ability to focus your lens manually. Here are some pointers:
1. Set your camera to Aperture Priority (Av or A).
2. Set your aperture f-stop number to the lowest (f4.5 f2.8 etc) if you want stars to be relatively still. If you want the stars to be streaking, go to higher f-stop numbers like f16 or f22.
3. Set your ISO to the lowest number possible such as ISO 200 or 100.
4. Set your lens to manual focus.
5. Place your camera on a tripod and compose your photo. Use your flashlight if you need help seeing the surroundings. You can also use your car headlights to illuminate the area to get a really accurate composition.
6. With your car headlights or flashlight on, use manual focus to accurately focus on your primary subject. This step is important because your autofocus will probably fail when you turn off your flashlight or headlights when you are ready to take the shot.
7. Turn off the lights and take the photo. Because your exposure will be quite long you don't really need to use a remote shutter release (however its always best practice to use one).
8. Wait awhile until you hear your shutter close, and the image pops up on your rear screen.
I took this photo of my classic early 70's Chev camper back in 2003 using Fuji Provia slide film. The only illumination was the full moon.
