how to photograph tonight's eclipse
Published Today at 9:36 a.m.
Over the Raleigh area tonight, a total lunar eclipse will be in the sky. Clouds willing, it will be a spectacular opportunity for some great photography. Folks with digital or film SLR cameras can use these settings:
BASIC SETTINGS
First of all, you will need to set your camera in MANUAL exposure mode. Automatic settings will not work. Every Digital SLR and SLR I have seen has this mode, and using the built-in meter will result in a huge waste of time. Like the old time photographers, just use manual settings. If you are not sure how to do this, read the camera manual or perhaps use Google to look up the model of your camera and read the instructions online.
Set your camera to ISO 100. The moon is brighter than you think!
A basic exposure of 1/125 second at f/5.6 while the moon is full and prior to the eclipse starting.
Change the shutter speed to 1/8 second within 15 minutes of totality.
Change the shutter speeding to 4 seconds throughout totality.
BRACKET your exposure on the shutter speed side. I recommend using half of the shutter speed (1/250) and then 1/4 the shutter speed (1/500) in the initial phase.
During the middle phase, 1/4th, 1/8th and 1/16th of a second.
Finally, 2 seconds, 4 seconds and 8 seconds during totality.
IMPORTANT:
A decent tripod is necessary. If you have a shutter release cable, use that. If not, use the camera's self-timer to fire the shutter hands-off. Any "shake" will make the picture blurry.
NEAT TRICK:
Use a short lens (35mm or lower) and a tripod and set the camera up to where the moon will arc across the sky but stay in the viewfinder. It will move right to left in a semi-circle above you, so center the moon in the middle left side of the viewfinder and leave it there. Fire the shutter using the settings every five minutes (be precise in this) and use the settings above.
Then, take your pictures and "stack" them using a computer program like "Image Stacker" and the final photo will show the progression of the picture as it moves across the sky. Image Stacker is a shareware application used for "star trail" photos, which is another really neat photo technique, but in the case of this eclipse it will work nicely. Or alternatively, use the camera's multiple exposure settings (look in the manual, it should have this) and do it all on a single frame.

Good luck and enjoy the eclipse!!!
