Cassini raw images
Don't know if I missed that this is already posted he Seems they
finally came to senses and publish the raw images from Cassini as they become available http://saturn.jpl.nasa.gov/multimedi.../raw/index.cfm |

Should come in handy when they start doing time-lapse on the ring spokes. OM -- "No ******* ever won a war by dying for | http://www.io.com/~o_m his country.

Anybody know if they took some or were they in the dark at that point? Or too close/fast to get a decent picture with those light levels? |

A color picture can't be a raw image. All pictures are somewhat black-and-white taken through some filters. Combining the right raw pictures produces a color image. |

First images should be being recieved within an hour, though, if I read this timeline correctly... Incidentally, I have pdf files listing the timeline for SOI, and one listing an overview one over the next month or so; these cover "tour sequences" SO1 and SO2. Is there a detailed one for any later sequence yet, or is that still dependent on how they tidy up this orbit? (I note we get a nifty Titan pass tomorrow, too) -- -Andrew Gray |

A color picture can't be a raw image. All pictures are somewhat black-and-white taken through some filters. Combining the right raw pictures produces a color image. Yeah, grayscale R, G & B or L, A & B or any off a plethora of others. So what was your point? If they sent RAW r, g & b channels it would be cake to combine them to form color images. If they in fact DID take color pictures (spare me the diatribe about multiple CCDs or CMOS, I know all that). |

Not sure if this will help but if you go to http://saturn.jpl.nasa.gov/news/press.cfm and download the PDF "Cassini-Huygens Saturn Arrival", on page 39 there's a diagram that charts the first couple of orbits, taking it through 15 January 2005. No timelines, though. -- bp Proud Member of the Human O-Ring Society Since 2003 |

AIUI, they select a filter setting, grab the frame, send that image, rotate the filter wheel, grab, send, rotate, grab, send, for as many "channels" (actually wavelenght bands) as they choose. Since these are RAW images, the work to make the color image is a post-processing step. The MER images work the same way, IIRC. /dps |

It's going to be trickier in this case; their speed of approach to the rings during the photo shoot meant that the three images needed for the color image weren't of the same view or scale, so they are going to need to manipulate them to create a theoretical view as if all of the three filtered exposures that were shot 60 seconds apart had been taken simultaneously: http://spaceflightnow.com/cassini/040701science.html Pat |
