"Paul Lawler" wrote in message hlink.net... "dude" wrote in message ... Would including a regular analog camera help at all for just getting the Martian sky color? They might have a heck of a time finding a 24Hour Photo on Mars to develop the film. An anolog camera can transmit to Earth. Or, like in the Voyager mission it could record it then transmit it back. This could all be done in analog if they wanted. But I'm sure they want the digital for more versatility. |

A "MarsDials" and a mini-DVD, provided by the Planetary Society, are attached to each rover and include colour-calibration targets for its "Pancam".

The MER team has taken a two-part approach to this problem. First, we calibrated the cameras before launch to determine how each filter will respond to sunlight reflected off Martian rocks and soils. Second, because we don't know how or if the cameras ' response will change after the turmoil of launch and landing on Mars, we carry with us a calibration "target" that has known grayscale and color properties. By imaging the target and getting its color balance correct, we will be assured that subsequent images of the landing site will have their colors properly displayed." Another big lie of the assclowns of the world exposed. Everything else is just nitpicking. Then what is the debate about? with color calibration doesn't that end the whole debate??? Mad ":scientist" isn't interested in debate, or science, or the truth. There is no debate. He just has a huge conspiracy chip on his shoulder. |

Your argument is identical with Hoaglands, but with opposite conclusions proving how much of a kook you are. No, this does not "prove" anything. Nor does your incessant yelling of, "kook" prove anything. |

Jay Windley wrote: "dude" wrote in message ... | | Would including a regular analog camera help at all for just getting the | Martian sky color? Possibly, but even regular analog cameras require color correction. There's a funny story about that from the old Star Trek series. They were doing makeup tests for the Orion dancing girl (the green chick) and the lab was unwittingly "correcting" her skin tone, infuriating the makeup artists. If you go back to the shot comparing the lander in the lab with the lander on the Mars surface, you can see that the strap is the wrong color in the onsite shot. You know it's supposed to be a certain color, and you can tweak the knobs until it comes out that color. But the problem is that the data that is supposed to render it the correct color -- that energy at 650 nm -- simply isn't there. Making the strap yellow (or whatever it's supposed to be) by the calibration chart biases the whole image uniformly. You haven't really accounted for that missing data. You've just adjusted the tint knob Another bit of movie magic: Back when we used blue screens to make traveling mattes, part of the process involved removing the blue film element -- which of course was perfectly white where the blue was and was thus useful in making the mattes. But to get the blue data back in the foreground image without spoiling the separation, the green component was printed with blue printing lights, and this approximated the original foreground colors. The green element would be black where the blue had been in the original scene, so it wouldn't print. But the colors would never come out exactly they way they were supposed to. You can't substitute green for blue without wrecking something. But it was deemed close enough for the general public, and you just knew not to allow certain colors in the foreground elements. | But since there is a palette can't they just calibrate the camera and go or | are you saying for the most accurate interpretations they would need that in | every shot? To be scrupulously accurate we'd need it in every shot, because the incident wavelengths can change over time. Light on earth changes wavelength between sunny and overcast for example. Most people just aren't that picky about exact color. It's only important if you're trying to get perfect visible light shots. That's what most of the public is interested in, but that's not necessarily what the scientists want to see. They're happy working with the raw elements. | Thanks for the informative response though, they can't accuse you of just | being a blind debunker now......... You're welcome. I may be wrong on occasion, but I'm not blind. You're still blind to the blue sky. Must be those pink filters causing you color blindness. |

I am not the one doing the disrupting, its the alt.astronomy kooks doing
so, and that is obvious to anyone watching the number of obsessive posts by these kooks.
