"Cheer up!" they said, "It could be worse!" So I did, and it was.

Dwight, here's a question for you. Your DVD includes a picture - colorwheel.jpg - that I've seen elsewhere with the same color rendition. It seems to show color filters that are yellow, magenta and cyan, the subtractive secondaries, as opposed to the red, green and blue additive primaries. I'm confused. Didn't the apollo system work as an additive color system just as the NTSC system does?

Dwight, did you notice this exchange on the "NASA WEBCAST 2009" which is on your books DVD?
Reuters Reporter: "Why didn't you use the original set (of tapes) that you used to fake this landing in the first place"
Dick Natzger, NASA Engineer: "Use the original set?"
Reuters Reporter: "I'm just trying to make a joke"
Ha ha...

ka9q the reason for the "negative" colors is because it is reflected off the filter color. I had a filtered light for the living room and the actual color of the filter was always anti to what it really was when I held it under a light. When I looked through it to the same light I would see its real filter color. If you scan the photo into photoshop and make it into negative, you'll see the familiar red blue and green. It has to do with the filter's absorbtion/reflection characteristic.
Ginnie you know even though the joke fell flat, it did raise an interesting question - why didnt they just use the same "set" if it was filmed on a set? Why try searching for 6 six years for those tapes?
Funny thing is, the ENTIRE hoax community only suggested things were afoul re the tapes AFTER the tape serach team announced what they were looking for. No one. Not one hoxer believer ever remotely suggested the SSTV tapes would yield a better image prior to this.

Re the hoax "community" (strange word since they agree on very little) I think they make a big deal about the tapes only because they knew they can't have them. If they had been found they simply would have labeled them as fakes.
Most of them don't even know how and why those tapes were made, what they contained, and what value they would have today if they'd been preserved.
Recently over on Youtube, a few of us had the fun of informing a few hoaxers complaining about a lack of stars in Apollo pictures that Apollo 16 returned plenty of them. Not only do they show stars, but a few include the earth, and best of all the pictures were taken not at visible wavelengths but in the ultraviolet that doesn't penetrate the earth's atmosphere. Not good enough, they complained, pictures of stars would be easy to fake...

the reason for the "negative" colors is because it is reflected off the filter color. Ah so! That made perfect sense as soon as I read it, so why didn't I think of it before? Many passive electronic filters reflect stopband components as they lack any dissipative components (i.e., resistors) to absorb them. I don't know much about optical filters but it stands to reason that they could do the same to their unwanted input wavelengths.

OK everyone. It is official this coming Thursday I will appear on www.spacevidcast.com as a special guest. The site has a countdown clock until the show, so you can set your clocks accordingly. Also the start time is listed in UTC format so you extrapolate the time for your area.

Q. What can be seen on Spacevidcast and has four eyes and three chins?
A. Dwight and a skinny interviewer.
(I swear, the devil made me do that.) ;D

I hope I don't forget to watch tomorrow night!

That was a fun interview, Dwight! ...and... I forgot all about it! Told you about my memory lapses... and I was watching "American Chopper: Father vs. Son" instead!
