Q: How do you shoot in how light?
A: Increase the aperture (lower the F number if not listed in fractions)
Q: What if that's not enough?
A: Well, lower the shutter speed, increase ISO, and if necessary, put the camera on a tripod.
Q: What if the object is moving quickly? Tripod is not going to help.
A: Then use a flash or flashes.
Q: What if no flashes are allowed?
A: Well...remember the panning technique I talked about a couple of days ago?
Q: What if the objects do not move in a strait line, but instead in many different directions and speeds?
