There is a thread about how to mark gels which made me think of this questions. When putting gels in lighting instruments I have always put the open end up to the top of the instrument. Never really gave it a thought until I worked with one company that insisted that you should always put the open end down and you were an idiot if you didn't. In the greater scheme of things I don't see it makes a lot of difference but curious if it has been taught one way or the other.
My thought was it may have come from rock and roll and trusses with PARs. I also have worked with another company that insisted on not using the retainer clips on his PARs.
