Since there isn't much happening with the planning for my trailer or trip, I decided to do a page on photography.
Many of us has seen beautiful moons in our travels, but have been disappointed in the results when trying to photograph it.
- Set your ISO to the lowest value possible. Typically, this will be 100.
- Set your aperture to f: 16.
- Use the "Sunny 16" rule to determine your shutter speed. The Sunny 16 rule is used to estimate exposure for bright sunlight. According to the rule, when the aperture is f: 16, the correct shutter speed will be the ISO of the camera. Although you are shooting your photograph in the dark, the light coming from the moon is reflected sunlight - it is quite bright. So, if your ISO is 100, choose the shutter speed as close to 100th of a second as possible.
- Although a tripod will help, if your shutter speed is over 100th of a second & you are reasonably steady, and don't have a real long focal length lens (over 200mm or say 15X) you can probably get away with a hand held shot.
- Even with a tripod, if your exposure ends up longer than a couple of seconds, the moon will move far enough during that time to blur the image. To make long exposures you will need a astronomical mount that is capable of tracking.
- You don't need to wait for a full moon - you will often have more interesting images when you can view the terminator of the moon because it accents the mountains & valleys.
