2 No Stars 1.Should photos from the Moon show stars? 2.Cameras can expose either dark subjects or bright subjects but can rarely expose both. The surface of the moon only reflects about 8% of incoming sunlight. However, compared to the sunlit surface of the moon, stars in space are dim.

3 No Stars 3.? 4.A. A series of slides that are designed to mimic the surface of the moon will be projected onto a screen and photographed using a 35mm digital camera mounted on a tripod. The room will be dark. The photos taken will be compared to the original slides to see if any stars have disappeared.

4 No Stars 4.B. Materials used during the experiment: Olympus 35mm digital camera, tripod, computer, projector, screen 5.Data and Observations…

20 Crosshairs 1.Why do crosshairs sometimes disappear behind objects in NASA photos? 2.Most of the missing crosshairs fall behind bright white objects. Bright objects in dark scenes can “overexpose” film because the camera shutter stays open too long.

21 Crosshairs 3.? 4.A. A series of slides that are designed to mimic the surface of the moon will be projected onto a screen and photographed using a 35mm digital camera mounted on a tripod. The room will be dark. The photos taken will be compared to the original slides to see if any crosshairs disappear.
