For you Lighting teachers out there that love the interplay of physics and light and perception. I assume you long ago knew the nature of "why the sky is blue" and that it has nothing to do with refraction as is often taught but rather through the process of scattering. But it seems we didn't get the full story! I had learned that the specific wavelength of blue was interracting with the spoecific size of the oxygen and nitrogen atoms resulting in the scattering but that turns out to be a simplification. Actually the range of scattering happens for all wavelengths shorter than blue, so the scattering would equally apply in the violet range. And as sunlight has roughly equal components of blue and violet the obvious question would be why the sky looks blue rather than violet! The answer to me was obvious as the explanation affects our well known theatre phenom of green and red light looking yellow....but it seems that there had been little explanation of the "why does the sky not look purple" problem in the world of physics. For those interested, MSNBC's website offers a pretty clear explanation at: http://www.msnbc.msn.com/id/8631798/ But for those who want a tad more info, long ago I came across a detailed explanation of the red + green = yellow illusion. The article gives a nice general explanation. From my own knowledge in this one here's a tad more info... Although it is now known that we have three color receptors in the eye matching what we call the lighting primaries of Red, Blue, Green, each of these receptors has a very specific sensitivity curve that can be graphed. If you mathematically add the graphs of the green receptor and red receptor sensitivities to the spectra you get a very interesting resulting curve with a clear additive peak right in the mid yellow range. Since "hue" can be defined as the "dominant wavelength" in the spectral response, we perceive the addition of these two response curves as yellow. It is fascinating to see the three graphs right above eachother: red response, green response, and the result of stimulating both cones. If there is a demand I could put these graphs online. Now we know the same thing happens in our perception of the sky. It's filtered through the specific idiosyncracies of the receptors in the eye. The article explains this nicely. As a photographer I have seen a similar effect (as I bet have you all) with slide film. Often a wonderfully deep rich blue/violet in a cyc or stage lighting, turns towards a far less saturated white (even with proper exposure) in slides. Obviously in that specific range of blue/violet the film's red other layers are responding thus diluting the saturation of the final photo.

RS-485 (the basis of DMX) with one transmitter at one end of the wire and one receiver at the other and good wire in between should be good for approaching a mile. >What happens if I add in a DMX repeater/optosplitter?

The wire length starts over at the splitter.

I'm a little skeptical of the Ocean Optics unit. I can't imagine that moving the lens 6" away from the reflector does anything good for the output of the fixture. I don't know anything about your facility or your needs, but these units are all fixture-specific. The advantage of a conventional scroller is that you can stick it on a PARcan or on a Source4, depending on the needs of the show.

For the time you're going to $pend running all that cable, is it worth thinking about going wireless for those two units? Or can you get a cheap show controller (Strand 310? -not so cheap but that idea) and preprogram the outdoor units and just let the controller autopilot during the gig. Streamline the show? But that means fewer toys! As Jerry said, RS-485 is good for the distance, and adding in a splitter/amplifier will help. Steve L. -- Stephen C.

I don't have a manual handy, but look at the standalone or demo modes that they have. You may be able to just program them once, and then they will just do their little dance all by themselves. The other thing is finding one of those little DMX playback boxes. You insert a loop of DMX settings, and it will sit there and play those back out until you shut them down. Jerry Durand makes one. Other folks also make them. Need a PC and the software to setup the program. http://www.interstellar.com/products.html --Dale ------------------------------ Message-ID: <42E02BE8.3060505 [at] StudioOneSB.com> Date: Thu, 21 Jul 2005 18:12:40 -0500 From: Richard Bakos Organization: Studio One Inc.

I have experimented with them for about one hour. I was operating them with a Strand 530 with no problems. What I did discover while playing was the reds were really nice when mixing Magenta and Amber to different degrees. Throwing the "extreme magenta" wheel in to the mix produced the best looking (saturated) reds I have ever seen while using a conventional fixture. (S4 750 watt) In the limited time I had playing I could not come up with a CYM combination that made a deep blue that was equally as impressive as the deep red. With limited time, I could not find that killer blue combination. When I return to the theater I will try again. I have not experimented with how it effects the optics of the source 4. From what I saw it still operated like a 26 degree unit. Gobos, shutters all worked fine. Are they worth it? Power Supplies are on board no extra box needed. I guess I would need to put a pencil to what I've spent on the Color Ram equipment (Scrollers and Power Supplies) along with 31 color gel strings over the years to know if they are worth their cost. From what I've seen so far they look like they are. The lenses assemblies, motors, glass color filters and housing are all top quality. Good looking, solid units. I was told the DMX components designed by Milton Davis at Fleenor. Ocean Optics also makes the dichroic glass for the VL 2 & 3000 units. So they know what they are doing when it comes to making color filters. If you have any questions about the SeaChangers I would be happy to look into them for you.
