OK, a somewhat realted question, what part of the
ERS actually inverts the
image. I have heard that it is the lenses, and I have heard it is the
reflector. I was then convinced on the
reflector idea because it makes an
ellipsoidal shape, which has 2 focal points. the forst
focal point being the
bulb, and the other being beyond the shutters/
gobo/
iris slot therefore, the beam crosses after the shutters/
gobo/
iris, thus inverting it. (the
iris of coarse doesn't matter, since it is...an
iris...)
But, then, I was walking around with a
lens tube, and looked down, and saw my feet in front of me. (36 degree) I was holding it at about the same height as to where we
drop our
electric down, and focus them on the
ground. If my feet were inverted, and the
reflector is also inverted, it would just cancel out. So, I guess my real question is, where are all of the focal points in an
ellipsoidal (particularly S4, if it matters).
(a diagram like propmonkey's showing the path of light would be helpfull)
Another random question, we also have a lot of Source 4 Pars, and when you look through the
lens at the
bulb, it looks green, yet they all give off white light, and the bulbs are regular
HPL's (with the little pokey thingy to lock it in...you know what I'm talking about...). I have tried to take the
lens out, but I'm not entirely sure how (all the tiny screws holding the front together looked important, and I didn't want to tinker without knowing what I was doing.) So, unless the
reflector, or something down there is green, then why in the world does it look green down there, and why the heck did
ETC decide to have the
lens spread the beam out like an oval, and have it be rotatable...
Anybody who can answer these questions gets browny points...
