Why does NASA have to "colorize" its photographs?

First thing: They aren't "colorized". Second thing: the Venus surface
pictures were not taken by NASA. You seem incensed by any suggestion that you are looking for some sort of "conspiracy", but it is your own fault. You persist in taking an argumentative stance, pushing for something anomalous where there is no anomaly. RM "Flying _Naked_People" http://www.rcip.com/nerdgerl/email.htm wrote in message ...

NASA even **admits** their photos are colorized! Are you insane? No. You are confusing "colorization"---where a black and white image has color artificially and arbitrarily added to it by hand, more or less like someone might tint an old photo---with NASA's use of color enhancement, where the colors in an exisiting color image are manipulated---enhanced---to bring out certain features. For instance, by increasing the contrast in a photo, features can be seen that would be otherwise invisible. Colorization and color enhancement are two quite different processes. You seem incensed that I ask questions you can't answer. Who says they can't be answered? A little more research plus a phone call to Charles Vick (the leading authority on the Soviet space program, who, fortunately, lives only a few miles from here), revealed this: The Venera spacecraft were constructed of pretty much the same materials as most other Soviet spacecraft---and US spacecraft, too, for that matter. These materials included (and I've added their melting points in degrees F) stainless steel (2550), aluminum (1218), copper (1981), titanium (3263), tungsten (6150), various lightweight copper, magnesium and aluminum alloys (all with melting points well over 1000), silicon (about 2605 depending the compound), quartz (for the camera windows---2912) and assorted ceramics. There was no film in the cameras---they were video. As has been pointed out to you already (and repeatedly at that), the main protection to the spacecraft was not the materials used in its construction but the special cooling system built into it to shield the instruments. And even that managed to last only a few minutes. I hope this answers your question. RM |

Once upon a time (Sun, 07 Sep 2003 00:47:50 -0000)
Flying _Naked_People took a deep breath and said: Why does NASA have to "colorize" its photographs? *All* the space agencies / organisations which take pictures from space colorize the pictures taken (if they are in greyscale). Or, in fact, only some of the images. Anyway, this is done for several rather good reasons: 1) PR value. Grayscale images = boring, color = interesting. They sell better. They interest the public and the press more. They make a person's imagination flow more. 2) Seeing images in "kind-of-real-color" gives the scientists a "kind-of-real-life" experience of the imaged areas. Makes the imagination flow again and interpretation easier. 3) Combinations can reveal more details than individual separate images. See below: Two images taken from the same area in two separate wavelengths reveal much detail even individually... --------------------- --------------------- | | | CCCCC | | XXXXXXX | | AAAAAAA CCCCC | | XXXXXXXZZZZZZ | | AAAAAAACCCCBCC | | XXXXXXXZZZZZZ | | AAAAAAACCCCBCC | | ZZZZ ZZZZZZ | | AAAA CCCBBCC | | ZZZZ ZZZZZZ | | AAAA CCCBCCC | | ZZZZ ZZZZZZ | | AAAA CCCBCCC | | ZZZZ ZZZZZZ | | CCCBCCC | --------------------- --------------------- ....but combining them shows many more units which can not be recognized from individual images. --------------------- | NNNNN | | MMMMMMM NNNNN | | MMMMMMMPPPPqPP | | MMMMMMMPPPPqPP | | OOOO PPPqqPP | | OOOO PPPqPPP | | OOOO PPPqPPP | | PPPqPPP | --------------------- The only thing often forgotten about these images is that when you see one, it looks natural... but in fact it is often a combination of pictures taken in wavelengths we can not see. For example, if the camera isn't equipped with a red filter but "sees" only in IR - the "red" we see in the image is in fact taken in the IR band. And so on and so on... But it is often close to the real thing. Educated guesses, you know...
