well... there can be the case when $200/hour is a reasonable price >> if a camera guy supplies all the equipment + light
of course, I am talking about the pro equipment
... every producer knows that you don't need much to shoot amateur videos, but the case is different if you want to shoot Glam Porn as good as possible.
+ an experienced and skilled cameraman will save you loads of time + money where inexperienced one can destroy it all..
I suppose it is all about the budget of the project.
