I have been trying some existing light photography, and have learned some things that work and some that don't. In addition to the constellations, I tend to photograph things that are lit, even if dimly. You will note that the light source in this picture is red -- astronomers always use red lights when observing, because red affects night vision the least.
Last night I was searching for photographic targets on the gravel road that runs through the camp, when I came upon the snack shed (also lit only in red light). So I set down the tripod on the grass off the road, and was focusing on the building when I noticed a man walking towards me, with a camera around his neck. As he got closer he saw me standing there and said, "Geeze. Every time I want to take a picture, a photographer is already there!" and then he walked away. Now:
- It is a long road, and the side of the road is wide, so there is a lot of room for many people to take photographs at the same time,
- If my spot was the only one that would do, I would have been finished and gone about 30 seconds later, leaving this perfect spot of all spots all to him, and
- He was doomed to fail, anyway, because it was totally dark and he did not have a tripod. No vibration reduction technology is going to handle that one!
