Once again, altering time changes how your audience sees the everyday. Getting in close on the moon also allows them to see details they might not otherwise see.
Hints for shooting the sun/moon.
When shooting the sun, shoot it directly only at sunrise/sunset when there is a haze in the air to mask its full power, or shoot on overcast days.
If you must shoot on a bright sunny day, use a neutral desnity filter to cut down on the brightness so that you can actually see the orb.
When shooting sun or moon, be aware they do move and not straight up and down. Get familiar with their paths. Zoom in a close as you can and shoot about five minutes and check the direction. You can then place them in the appropriate corner of your screen, allowing room in the direction they are traveling.
