I don't get the digest, but I bet it's because people like me use the traditional two-dashes-and-a-space separator before our signatures. In a single message, it lets certain newsreaders drop off the signature lines - a useful thing when you're reading Usenet, for instance, and people have long .sigs. For Internet old-timers, it's considered a courtesy. But some modern newsreaders respond by rendering everything below the separator in a lighter-colored font. This is not a problem in single messages, but it sounds as if your newsreader sees one of those triggers in the digest and interprets everything below it - including other people's messages - as part of a .sig file. If I'm correct, then you'll see everything below this message in light grey. -- Pat Kight kightp [at] peak.org ------------------------------ Message-ID: Date: Fri, 29 Jul 2005 11:19:03 -0400 From: Delbert Hall Reply-To: Delbert Hall Cc: joechamp [at] gmail.com (Joseph Champelli) Subject: Re: list reading problem (question) In-Reply-To: References:

Actually, as an "old man" in this business, I'd be just as happy if the technology would stop changing until I collect my pension. Just pointing out that there are some pretty cool things we can do with these projectors- think of, for instance, a scene that takes place underwater, or perhaps a rainfall effect, or a wash of swirling colors. Just one more tool in the arsenal, but one worth some experiment, I think. Anyway, I've eliminated the 7V we had in the grounds when the houselights were on, I need to find something else to drive the sound guys nuts. And thanks for the explanation of LCD v. DLP.

It's basically a 4000 lumen LCD XVGA projector, in a motorized yoke, all contollable by DMX channels. Using the latest buzzword: convergence, that is with media/video server systems. And just looking at the their website, High End seem to have added something called "Digital Eye Technology" as an option, to be able to capture, at least rudimentary, images with these projectors to be used as further sources within their media server system. The article seems to claim being able to capture images that could at least be used as "gobos". Hmm. Smile for the projector!!!! Or am I reading too much into it? On the other hand, a few years ago, some one posted an abstract claiming to be either a Varilite patent, or patent pending, on the use of LCD elemants as shutters and/or gobos in lighting fixtures.

Following this came the "LCD" version of oil projectors (and other optical wizardry), GE's Talaria systems. Also along the way, there sprang up another system that became known as the "Image Light Amplifier", or ILA. One version used lasers as the light source and could be capable of incredible resolution, at the expense of very slow updates to images, like a new frame every few seconds or so. Some of this technology, and people ended up at Ampro's high end light valve division, which bought/merged with the Eidophor stuff, which has since disappeared. The other version of the ILA went towards using CRTs to control arc light sources, which was developed by Hughs. JVC got involved, and now it seems to be their baby. Recently, the CRTs were replaced by LCD panels, and the technology seems to be called LCoS, liquid crystal on silicon. Sony, among others is starting to also use this technology. As an adjunct observation, in the B&H Photovideo catalogue I got last summer, the most expensive video projector I saw listed in print, (not necessarily the most expensive they might sell, nor exist) was a three CRT unit!! Apparently, at the latest Infocom, some one was showing a very tiny video projector, using LEDs as the light source. The output was only in the range of 50 to 80 lumens, which is very limiting for applications at the moment, but at least the idea is being worked on.

In the digital domain, I don't entirely agree with you. The dynamic range of digital cameras remains inferior to film; merging multiple images taken in rapid succession and nearly identical except for exposure settings, simulates the wider range of film. Done right, the composite image will have the tonal and dynamic depth we expect from a good quality photograph, and replicate reasonably what we see with our eyes. Many of the best lighting designs demand this treatment when recorded with a CCD, otherwise detail in light areas will be lost in digital 1s, and detail in dark areas will be lost in digital 0s. Bracketing is necessary sometimes. In my opionion, anyway.

Maybe things have finally started to change in the last few of years. It has been a while since I last researched to best assistive hearing system for a venue. It would be great if loops became the default standard in the US. Unfortunately, I cannot justify it for our local theatre, as I have never encountered a patron that has or knows what a T-coil is.
