  1. We buy the rolls of wire mesh. Cut the piece you want as a rain cover. Give it a light spray with WD40. You'll never see any water anywhere near the fixture. And most of the time, because the mesh itself is so small, you don't even need the spray. The laws of fluid dynamics keeps the water out by itself.
  2. That's okay John. As a dog companion who can make his dog move his eyes up, I can tell you first hand that they do. As I said, it's not as far as you can move yours. But then again, try to move yours up and notice how useless it is to do more than 10 degrees and hence, like a dog, easier to move your head than your eyes. And the picture is untouched. Fun stuff from dog companions http://en.wikipedia.org/wiki/Wikipedia:Ref...dogs_look_up.3F
  3. I saw Spider Man swing on a thread in a movie too. :) Dogs have mostly binocular vision so do not have much in terms of eye movement but they do have vertical and horizontal capabilities. If I hold my dogs head and someone moves a biscuit in front of her both up and to the side, my dogs eyes track so sorry to spoil the myth. Owls have completely binocular vision and tubular eye balls so can not move their eyes at all and must use the head to do all looking. Notice the attached picture. The dogs head is shifted upward slightly and that the eyes too have vertical movement as the whites below illustrate. It is not full movement in terms of degree like a human but definitely moving the eyes vertically.
  4. Guess you don't have a dog. Yes dogs can look up. They have binocular vision so their eye muscles are not as elastic as your for vertical moment but indeed the eyes move vertically in the socket. Since they have binocular vision dogs tend to use the head to aim the eyes rather than the soceekts but that does not mean htey can't look up. Mine does it all the time.
  5. Yes cats have shorter neural paths in their eyes so instead of seeing a pristine picture, they see more flicking of a TV screen with images from that screen mixed in. Sort of like shooting off speed at a TV set just real off speed. Cat videos prove that cats do indeed see the picture though as they will swat at elements in the video and sometimes run around to the back of the set to catch what ran away. But more importantly cats use smell and sound more than they do sight. Sight to them is about movement. One reason cats don't look at themselves in a mirror. I saw a documentary that said cats usually recognize your smell and hear your voice which is more the key as to why they approach you over seeing you first.
  6. Save your money. you can buy twice the roll of wire mesh screen for a 1/3rd the price at the Home Depot.
  7. Nice stuff but way long due to the music choice which is repetitive and doesn't help your cause. If you sent this to me I'd turn it off at about 48 seconds as I'd be bored (where I wanted to while watching it). Tip: Faster cuts, get out sooner. It takes but a second for me to see and know everything about a shot so holding on multiple angles of the same scene gets old real fast. Not saying shots should be 1 second in duration just that it takes very little time for a viewer to get it. As a guy who looks at a lot of reels and hires lots of people, I'd say show me enough to dazzle me, and make me want more. Your material has the ability to do that but your reel doesn't
  8. I never asked for a capsule. I asked for the powering module. It is technically called a "K6 Battery, or Phantom Powering Module for all K6 Series Microphone Capsules". Whether it runs on button batts as old Senheisser's used to or AA, it's basically a phantom power supply module.
  9. This camera four forms of marker, safety-zone, center mark, aspect mark and guide frame lines. The confusion is that you are looking at the "aspect mark ratio" as "the safety zone". The camera IS a 16x9 camera. You can turn on the "safety zone" which is a picture safety marker or the "aspect marker" which is a marker for the sides only. None of this has anything to do with how the camera records.
  10. Looking for the base power supply module
  11. "Neither HDCam nor DVCPro is a "broadcast standard." They are videotape recording formats that have nothing to do with broadcast, other than the fact that some - and I emphasize, some - programs are either recorded or delivered on them. " I deliver dubs to over 50 markets in the US and all HD dubs require both mentioned in my post exclusively. By standerd I was referring to delivery standards (wait before you say anything). And sometimes I am told to deliver even against the standards of the company or network. Take PBS for instance. Many PBS stations I deal with can't afford HDCAM even though they are a 1080 network, so want dubs only in DVCpro. Forgive me, as I am hung up in the world of commercials and sometimes don't think outside of that. In my world, SR is not the option nor the choice for distribution 90% of the time, but I agree with your assertions for long format program delivery. I take back what I said. "Compression does not affect the pixel size of the original material, although it does of course eliminate a certain amount of information by definition. " I agree with your point and am talking less about what you start with but what you end up with aka "it does of course eliminate a certain amount of information by definition" "If you take a 1920x1080 image into Photoshop, and export it as a JPEG image, it's still 1920x1080. Anything else is determined by specific settings in the encoder. " To bad no one in the station is using photoshop and rather has encoders :) And since I deliver mostly HDCAM I'm not delivering real 1920. Have you been to any cable head ends recently? Maybe Cablevision in NY, or Comcast, or even the new verizon Fios center down in NC? Or have you been to any local stations to see some of the set-ups used to compensate for cost? SR is a great format, but man even in the top 15 markets I've seen some pretty amazing work arounds in the transmission chain. When you see them you realize why things don't always look like they should. And also realize why you want to start with the best signal you can on the acquisition end. "There is certainly loss, and there is certainly what appears as noise added - as well as motion artifacts and various other very nasty things - but the image size is not changed." Not when you deliver a SR dub. But what happens to that signal from head end to local transmission is what I am more talking about and it would surpise you to know how much digital degrades. I know I was just at teh hub of a large station group in the midwest and was told by the head guy, "we have it set up this way now, but hope to get it set up better sometime in the future is we can get the company to give us the money we need. But no one at home has complained... (he smiles and laughs)" "And, once again, HDCam isn't a part of this equation." Thanks again. I work too much in the commercial world and did say some things that do not apply to long format program distribution for a few (not the majority of network delivery). I take them back, but only for the few major networks that require SR delivery like CBS. Most all cable networks like discovery require only HDCAM and only get that, and many times footage was never acquired on anything but HDCAM if that. And if it was direct to a 900 or 950 it might be 1920 by spec but lacks in terms of methods of recording (unless as y And many of the older programs now seen in syndication never made it to SR originally. It's not the 1920 that is the problem but the compression and less than stellar way of recording in a camcorder unless as you say it uses an outside recording medium. But then again, my whole discussion involves the useless use of numbers as if they mean anything in the end. Is 1400 HD? Is a camera that has SD chips pixel shifted really HD? Is if half HD if it isn't 1920? Is 1920 true HD and more importantly does it matter that most all TVs that folks own don't and can't make full raster HD nor need to or that 10 out of 10 people can't see the difference of a 720p set from a 1080p set? Nope, cause HD is made in the mind and perceived by the brain and the numbers alone can't explain why the brain does that. In fact higher numbers often mean little to viewing. But folks sure want to find some kind of numerical nirvana with numbers alone.
  12. It will not make much of a difference. Both will look good and none of the specs you mention will really affect how it looks or should I say looks different in your scenario.
  13. Here's a marketing secret (spoiler involved): Actually you are on to some very deliberate self marketing methods I've accomplished over the years. By me being very vocal and somewhat gruff and flippant, with a heck of a lot of life experience sprinkled in for validity, I have basically created two kinds of people who know my name. Those that 'hate' me because they can't stand my practical and somewhat selfish, self-important look at life, and those that 'like' me for my knowledge, valid, and realistic view of the world. Really both sides are just the same thing with people interpreting them differently. Here comes the marketing part. The beauty is that whether you hate me (my persona on the web, I'm really a pretty fun guy to hang out with), or you like me, most everyone always wants to read what I say. I have very deliberately used some tricks of marketing and subliminal somatic advertising to create the persona I have on the web. It's really no different than those ads we all know where some guy screams at us on TV or the radio or does things a bit offbeat in an ad. One key is that we see it over and over and while we either love or hate the persona created, it makes us remember the brand, like it or not. We may not shop there cause we hate the ads, but we sure are curious about the store. Crazy Eddie and JGE Appliances if you grew up in NY come to mind. B)
  14. You're on to it. What you are referring to is saccadic movements. REM sleep is one form. But in that case your brain is “looking ‘ at a lot of images so the movement is far greater. There are five types of eye movements that allow you to see in a normal day and saccadic movements has a specific purpose. Microsaccades are 20 arc second involuntary moments of the eye. You cannot detect them. Without them you could not see well. The reason is that your rods and cones respond to differences in luminance. If you are standing in a room and nothing is changing as you stare at something your rods and cones would start to be over stimulated so the eye vibrates slowly to keep minute photon variables to reexcite the receptors in your eye so the data is over sampled and you can see. The over stimulus you avoid is sort of like flipping a hot potato between two hands to be able to hold it as the never get over stimulated if you tried to hold it in one hand too long. Visually it's sort of like radar where an object is scanned over and over at multiple angels to know exactly where it is and clearly detect the edges. So it helps is keep and image sharp as we use tiny variables in what receptors see to keep it fresh in your mind and not over stimulate the receptors too much. And we use saccaddes as radar to tell us the distance of two objects in view as we scan rapidly between the two giving our brain a 3D map so it can judge distance. In a way you could say that our eyes actually do compress time and space as these fast pulsations send information but not all information to the brain. Once again, the similarity to how TV works and even the blade of a projector can be made with these movements and their purpose. But the speed is not a constant and can vary much lower to your number to much higher depending upon the situation. In a way you can see its affect. Pick two objects in a room. Try to stare at an object and do a slow pan to another object. Notice how it’s really choppy like panning a film camera too fast… you can’t see a smooth pan as your eye must stop and rescan the field of view in order to evaluate if anything is important and keep it in focus. Also you might not notice but when you are curious about what you are looking at you tilt your head around to try to give the brain a slightly different impression of it for evaluation. And a few people do not have the ability to make these tiny movements with their eyes so do it with the same tiny head movements instead. This also helps your ears retune to hear slightly differently and to help evaluate the mystery. And finally, it's these movements that give your eyes about 20 stops of range as opposed to the six or seven they'd have looking at a static image without the re-stimulation of your eyes receptors. Hope I didn’t just give camera manufactures an idea. :) It’s sort of like not having an iris so you have to constantly move the camera so the pixels don't burn in. Doing so makes for less light on the receptors which send these pulses to the brain giving you the ability at creating a sharper image.
  15. The fragrance you smell is called RTX9338PJS otherwise known as "just cooked bacon cheeseburger-like fragrance. Good advertisers understand the fact that smell is the number one sense that makes you buy. Nike knows you’ll pay for their brand and pay more at their store in NY due to the very light fragrance they pump into the air conditioning system. I think the point of what I am presenting here is that subliminal advertising is all around you. The ear buds on Ipods for instance. Or the brown eggs in the supermarket. But it's not the myth that our culture has made it based on flashing frames. The public perception of subliminal advertising is akin to the stories and mythology told of vampires. Almost believable and if someone tells you a story, you might actually wonder if it's true. There are plenty of films where filmmakers put in flash frames. The Exorcist had them thirty five years ago and I'm sure plenty of others. I'd say it's more the filmmaker living the promise of the myth than based on anything else. Occasionally TV ads have some subliminal gimmick as I mentioned KFC did a few years back. But that too, is really more to call attention to the ad than to really delve into your subconscious. If it really was subliminal, we wouldn't be talking about it. I've never worked for any of the major advertising agencies to have anyone suggest some secret sort of ad other than a joke. I've never been in a creative meeting where we locked the door and presented some sort of secret code to inject into an ad. As I said, injecting frames into a film or ad does nothing to convince you to buy a product. But I also said that every day you are exposed to subliminal advertising. I was just involved with creating a scent and having it put in every dealership of a major auto group. It reinforces the company’s brand, and helps influence people to buy cars. How about the smoking warning on cigarettes and all the money spent on those creative ads 'designed' to make you stop smoking... nope, sorry, they actually make you want to smoke. When put under what is called functional magnetic resonance imaging (fMRI), the area of the brain that craves lights up when smokers are exposed to those warnings just as they are when shown a person smoking a cigarettes. Did you really think the cigarette companies would volunteer to spend millions doing ‘non smoking’ ads to put themselves out of business? Just before the UK banned cigarette advertising a company started a major campaign showing the company logo against a purple swatch of cloth. After the ban, they removed the logo, but still bought billboards with nothing but the purple swatch. And while the ads were not blatant, they sold cigarettes. Go look at the logo of any fast food company and notice the red and/or orange in the logo. Both colors stimulate hunger. So yes, every single day you are bombarded with subliminal advertising, but it's just not the stuff you expect because it's not based on some cultural myth created by a guy trying to sell projectors so he told everyone that flashing popcorn made people buy more. Truth is, you can't influence people to buy something they don't want. But you can remind them of what they like or use somatic memories to make them associate your product with something good in their life.
  16. Here's a fact based on extensive recearch. Flashing frames on a TV screen has no effect on anyone. If someone wants to monitor it, good luck. It's a waste of time.
  17. No one ever monitored subliminal advertising in the US. As the few examples I gave along with others done over the years show, there is usually a more deliberate form done, an assumption that something is (backwards record albums). But fear not, all the research shows that much of what one could do on TV in the form of subliminal advertising has absolutely no effect on you. None of the major agencies I've worked with every had a subliminal ad lab in the back room. It's more myth than reality. It's myth that captures or imagination more than reality driven by the notion that the prospect of something flashing on a screen for an instant could drive us to do something we have no control over. It scares people. It's the reason why the 50's experiment raised feathers. It was the cold war and we were already terrified that something was going to invade us. Often our minds make things far worse than they ever could be. I work with a number of groups that do all sorts of fun stuff regarding trying to talk to your reptilian brain. But none of it will change your life. Maybe make you remember a product, but never make you want something you don't want or need. So have another sip of that Coke. Then go out and buy Pringles. :)
  18. I'll see if I can help. This is NOT an F900. It's a less expensive video camera made more for TV/doc shooting. It has the same basis as the F900 in terms of electronics without the range. It has adjustable gammas as do all professional video cameras. It's 10 bit as opposed to 12 bit on the F900. It has less range than an F900 in terms of exposure/contrast and simpler handling of both low and upper exposure. I could continue but I think you get the point. It's a camera designed for the market below episodic TV. Still makes a nice picture though. Has many of the same menus as a 900 designed for engineering and proper camera adjustment.
  19. Both cameras have similar menu structures. You can try some 900 settings that will work quite well or give you some looks you can further tweak. Here's one opinion: http://petergray.org/F900paint.html
  20. It still has to be synced and is still affected by the electronic shutter when in default 1/48th at 24p
  21. Not blaming you as much as reminding people. I am amazed how easy it is for opinion to turn into fact. Science is itself very limited. Currently less than 20% of all medicine has any scientific basis behind it according the US GAO. Point is most of what doctors do is no better or worse than any other treatment, yet we believe the dogma of allopathic medicine as if fact, and many times even when what a doctor tells us goes against how we feel. Watch the news and see such stories presented as 'wine helps prevent heart attacks', yet the science in no way says that is true, but everyone believes it, just as they say high cholesterol causes heart attacks even though there isn't a shred of science to show that to be true. Amazing how fact is born and feeds more myth that becomes dogma. Makes lots of money for some.
