Here comes the sun. This is easy enough to see if you are standing in the right place.
But it gets challenging if you try to look up at the sky while in an upright position. Very risky, actually. It was worth it.
You can be a contortionist if you try to photograph the reverse side of the cloth as it approaches the cloth beam. This is not as risky, especially in a carpeted room, as you are closer to the floor and don't have as far to fall.
No contortions necessary when photographing the top side. More blended overshot and rosepath.
In the Department of Books, I just finished reading The History of Love by Nicole Krauss. Moving, funny, surprising, suspenseful.
