Techniques on how to use flash lights.

In cave photography you can't be alone. You need help in your work. You need a friend, better if two, that have with them a flash. You call him flashman. He must do everything you tell him, becouse you make the photos and you are seeing what picture you want to take. He really must be your friend and in most cases he will hate you at the end of the day! It is important to know all the  methods used to illuminate caves with flashes. In many cases more flashes you use, the better will be the photos. Two methods can be used. One is the open flash method. It consists in having your camera in B position and on a tripod. In this position all the flashman let there flashes on and after that the B position can be closed. Another method  is to use a flash on your camera and have all flashman with slave flashes. When you take the picture all the flashes will light up simultaneously. This is the method I prefer, it is better controled by you. 

The pictures in this page show you all the methods to use in a hypothetical tunnel.
