I am in France with an new arca-swiss disovery and I have a couple of quick, i.e. dumb, questions.

I have figured out the controls except for one thing. How do I get the camea back into position for horizontal photos? Presumably it revolves, but I can't figure out how.

Also, I need to increase the tension on my ballhead, a B1, because this camera is too heavy for the current tension. I don't have the instructions with me on increasing tension. Can someone tell me how to go about it?

Thanks.
