I've always brined my cams, haven't had any issues before. I am interested to try dry salting as it should be quicker.
I would guess that it has the same result. Dry salting is not quicker in one sense - I generally salt my cams over about 48 hours. But it is a lot quicker and easier in another sense - I put 1/4 of the salt on the top, and let it sit for 12 hours; flip and put 1/4 of the salt on what was the bottom but now is the top, let it sit for 12 hours; repeat twice more. On the last flip & salt, I go ahead and put it in a ripening box in the cave. It doesn't matter if it is more or less than 12 hours, and only takes a couple of minutes to do the salting, so this way I am not tied to the cheese the way I would be if it were in brine - waiting for just the right amount of time to take it out.
So, just to be clear: I make a set of cams one evening; let them continue to drain until the following evening. Then I salt one side. The next morning, I flip and salt again. That evening, flip and salt again. The next morning, flip, salt, and put in the ripening boxes in the cave.
